Let's say there's a type. T where T: struct♪ How do you get his memory address?

unsafe private void SmthMethod(T* a) {} //ошибка
unsafe private void SmthMethod2(T a)

{

fixed(T* b = a) { } //ошибка

I've been thinking long, but I think I've learned the challenge, and that's the solution:static void Main(string[] args) { int[][] myArray = new int[10][]; Random rndGenerator = new Random(); int count; Console.Write("Введите число элементов массива: "); while (!int.TryParse(Console.ReadLine(), out count) || count <= 0) { Console.Write("Неверный ввод, попробуйте еще раз: "); } for (int i = 0; i < myArray.Length; i++) { myArray[i] = new int[i < myArray.Length - 1 ? 10 : count % 10]; } for (int i = 0; i < myArray.Length; i++) { for (int j = 0; j < myArray[i].Length; j++) { myArray[i][j] = rndGenerator.Next(-30, 45); } } for (int i = 0; i < myArray.Length; i++) { for (int j = 0; j < myArray[i].Length; j++) { Console.Write(myArray[i][j].ToString().PadLeft(3, ' ')); if (j < myArray[i].Length - 1) Console.Write(", "); else Console.WriteLine(); } } Console.ReadKey(); } ConclusionВведите число элементов массива: 93 -1, 21, 14, -29, -14, -1, -22, 30, -27, -22 -22, 22, 32, 12, -24, 19, -16, 41, 23, -4 -10, -23, -2, -29, -23, 11, -7, 38, 23, 18 -13, -3, -10, 11, 20, 35, 5, 7, -2, -6 -30, 43, 16, -4, -8, 28, 32, 24, 12, -6 21, 1, 7, -9, -18, -8, -7, 12, 39, 20 -24, -15, -23, 0, 36, 26, 2, -10, 37, -15 -17, 22, 13, -1, -5, -9, 5, -29, 23, -7 23, 14, -5, -2, 42, 30, 34, 43, -1, -3 11, 38, 13

I add group code.The idea is to group objects by JMPM_ProductoID and JMPMD_ModificadorID. With that grouping all objects will have those two things in common.For that, only the objects that have detail are filtered and the others are ignored.Then you have to choose one of those objects, in this case the first and the detail of this object add the sum of all the details of the objects of this group.At the end you have a collection that has only one object per JMPM_ProductoID and JMPMD_ModificadorID.Then the collection is added to the objects that had not been included for having no detail.var data = llena(); // crear lista con objetos que tienen detalles var registroConDetalle = data.FindAll(d =>d.JMPMD_MesaProdmodDetalleLista.Count > 0); // crear grupos por JMPMD_ModificadorID y JMPM_ProductoID var grupo = registroConDetalle.GroupBy(g =>new { g.JMPMD_MesaProdmodDetalleLista.First().JMPMD_ModificadorID, g.JMPM_ProductoID }); // de la nueva colección agrupada seleccionar el primer objeto //y guardar en su detalle la suma de JMPMD_Cantidad var objetosFusionados = grupo.Select(g =>{ var objeto = g.First(); // elegir el primer objeto // guardar en su detalle la suma de JMPMD_Cantidad de este grupo objeto.JMPMD_MesaProdmodDetalleLista.First().JMPMD_Cantidad = g.Sum(e =>e.JMPMD_MesaProdmodDetalleLista.Sum(de =>de.JMPMD_Cantidad)); return objeto; }).ToList(); // de la colección original recuperar los objetos que no se incluyeron // por no tener detalle y que coinciden con el id de los objetos fusionados var objetosNoIncluidos = data.Where(d =>objetosFusionados.Select(d1 =>d1.JMPM_Grupo).Contains(d.JMPM_Grupo) && d.JMPMD_MesaProdmodDetalleLista.Count == 0).ToList(); // agregar los objetos no incluidos objetosFusionados.AddRange(objetosNoIncluidos); // agrupar para impresión y actualizar totales var resultado = objetosFusionados.GroupBy(r =>new { r.JMPM_Grupo }).Select(o =>{ var total = o.Sum(d =>d.Cantidad); o.ToList().ForEach(e =>e.Cantidad = total); return o; }).ToList(); // impresión de resultados resultado.ForEach(re =>{ re.ToList().ForEach(r =>{ Console.WriteLine("Padre:"); Console.WriteLine("Grupo: " + r.JMPM_Grupo); Console.WriteLine("Cantidad: " + r.Cantidad); Console.WriteLine("ProductoId: " + r.JMPM_ProductoID); Console.WriteLine("Hijo: "); Console.WriteLine("MesaProdmodDetalleLista: " + (r.JMPMD_MesaProdmodDetalleLista.Count == 0 ? "0": "")); if (r.JMPMD_MesaProdmodDetalleLista.Count != 0) { Console.WriteLine("\t-ModificadorID: " + (r.JMPMD_MesaProdmodDetalleLista.Count == 0 ?

Sometimes it's good to just shut up and shut the TS.Object.keys(extra).forEach(key => { // @ts-ignore this[key] = extra[key] }) But in your case, instead of the conditions and the bulkhead, it's more logical and easier to use.Object.assign(this, extra) http://www.typescriptlang.org/play/#code/C4TwDgpgBAyg9gYwJYEMA2UC8UUDsQBQoksAogPJY74EFK7AQBOAZigtAIpQDeBUAqAHohUALQAaMQQC+BBGhQBnJVG59BUMAFcARmiQIoSiHAD8ALjLkA3P0E79h44lRpLsV+jv2BCOLhKwEzaCMBwTAAUYChMKAC2SlacAHQAJDFxiQCUvL6aUP6BwLxQwEjAaBAShQGMDDUAJiiMACpI8dVQSI01Kf0QAB7BKFAyVJkJSnYFgkgsUJFDI7kaswUi4mJQ5ABK+es7ugBWEGEpykpIAOa4kcAAFkhKNctx2Qfrm2Lbe5+zm3IJzOwBSAGsICAlEthu8UiwIqR2A9IhCQFgAHx5Q6aTa40QAAWASjEN1wEQg-w2ok0j2eAG00QBdKhvFCMyFMqn4sYfQ5yTRyOS4BIQJQxDhqbGCb6-faaIZgCIlYjQDKxKZUbgAMmls3KlQgVjwIBm6yK9WAxvwZtmzTaHSN1FNVJ61pdgvysp28plokVyu6DGYbEl6qyqmWEFwjVU6i9NMEBqq7ttwkTfjq0atzrTeME9og7U6qYTBTdubLQqAA a little code

Thus, in order to achieve this objective, we should first adopt a class that we will indicate our application as a source of data for the link (see annex).DataContext♪ Let it be an empty class with a name ♪ MyDataClass:public class MyDataClass { } Okay. Then we need to create a simple class for one element on our list. Let it contain some sort of thing. string by name Name and a collection List<string> by name Films♪ First class. Category:public class Category { public string Name { get; set; } public List<string> Films { get; set; } } Okay! It is now possible to create in an earlier class. MyDataClass empty (at present) ObservableCollection<>♪ Call her. MyCategory and let it initialize. Our class will be like this:public class MyDataClass { public ObservableCollection<Category> MyCategory { get; set; } = new ObservableCollection<Category>(); } Okay, the floor's on the way, there's still the design of the elements, and it's all connected. Let's get started! ♪ MainWindow At the beginning, we will create ours. MyDataClass:public partial class MainWindow : Window { private MyDataClass MyData; } Then after InitializeComponent(); We need to initialize this class and ask how DataContext♪ Also, let's just fill all this inaccurate test data:public MainWindow() { InitializeComponent(); MyData = new MyDataClass(); DataContext = MyData; MyData.MyCategory.Add(new Category { Name = "Боевики", Films = new List<string> { "Фильм 1", "Фильм 2", "Фильм 3" } }); MyData.MyCategory.Add(new Category { Name = "Комедии", Films = new List<string> { "Фильм 1", "Фильм 2", "Фильм 3" } }); } Well, it's almost finishing. There's still a visual element. ♪ WPF Consider each element to contain a lot of others (for example, we can put a picture in the button, text or something). In our case, we can redesign the cell template from the element. ListBox on the one that contained a text field and another ListBox:<ListBox ItemsSource="{Binding MyCategory}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Name}"/> <ListBox ItemsSource="{Binding Films}"/> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> I've already indicated the data for the connection, namely:Basic ListBox indicated ItemsSource="{Binding MyCategory}"that linked him to our collection. MyCategoryTextBlock - He was told where he should take the text. Text="{Binding Name}"♪ I mean, a tied collection. MyCategory contains elements of a type Category That's where we pointed out. Name and finally got attached.Internal ListBox - Well, it's clear, we gave him our list. Films♪Well, let's get started. The result should be as follows: If you move on. Binding, in this case, if you change the collection of any elements, you'll probably not have a visual update. A lot of people are scared. BindingHa. I'll write it right away! It's easy, it needs to be implemented. INotifyPropertyChanged where something can change. In our case, it's class. Category♪ We'll put a few lines in it:public class Category: INotifyPropertyChanged { public string Name { get; set; } public List<string> Films { get; set; } public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); } Now we have to rewrite what might be renewed, like the name:private string name; public string Name { get => name; set { name = value; OnPropertyChanged("Name"); } } That's all, now our interface will update the Ima field (Name) in line with the changes in the collections. MyCategory♪ It's better to use the lists. ObservableCollection As she knows how to report data change.What you need is just an example of how to place. ListBox inside another ListBoxbut I thought it would be useful for you to find out how all the data ended up tied up and how to use it, because it's the basis and the "s." WPF♪ Trying to write everything as detailed as possible in order to clear it. I hope so. Good luck!

Why Arrays implements IEnumerable but does not implement IEnumerable<t>?</t>

Array definitely implements IEnumerable<T>. Try it bool isIEnumerableGeneric = EpisodesList is IEnumerable<Episode> and will see that the result is true.The reason for the describing behavior is due, according to I understood https://msdn.microsoft.com/en-us/library/system.array.aspx , is that the implementation is only "disponibilized" (provided) in runtime and therefore interface generic does not appear in "declaration syntax" of class Array. Trecho taken from the documentation: Starting with the .NET Framework 2.0, the Array class implements the System. Collections.Generic.IList, System. Collections. Generic.ICollection, and System. Collections. Generic. IEnumerable generic interfaces. The implementations are provided to arrays at run time, and as a result, the generic interfaces do not appear in the declaration syntax for the Array class. In addition, there are no reference topics for interface members that are accessible only by casting an array to the generic interface type (explicit interface implementations). The key thing to be aware of when you cast an array to one of these interfaces is that members which add, insert, or remove elements throw NotSupportedException. Which translates to Portuguese is:From the .NET Framework 2.0, the Array class implements the System.Collections.Generic.IList, System.Collections generic interfaces. Generic.ICollection and System. Collections. Generic. IEnumerable. Implementations are made available for runtime arrays, and as a result, generic interfaces do not appear in the Array class declaration syntax. Additionally, there are no referenced topics for interface members that are accessible only when performing cast from an array to a generic interface type (explicit interface enhancements). The important thing is to be aware that when you do cast from an array to one of these interface is that the memebros that add, insert, or remove elements launch NotSupportedException.

The tree structure here is easy to understand, considering the abstract syntax tree of the type.given under Shape Typedata Shape = Rect Double Double Shape For example, Rect 1.0 3.14 I think. The wooden structure corresponding to this section is as follows.Rect ├── 1.0 └── 3.14 This is a translation of a rectangle with a length of 1.0 and 3.14.Rect The constructor receives two arguments, so the tree structure has two nodes.More Tree Typedata Tree = Empty | Leaf Int | Node Tree Tree Examples of tree structures in this section are:Node ├── Leaf │ └── 100 └── Node ├── Leaf │ └── 200 └── Leaf └── 300 This is a tree with three leaves. NameNode (Leaf 100) (Node (Leaf 200) (Leaf 300)) HomeNode Constructors Leaf Note that the number of arguments is different in the constructor.In addition, the example is also included in the "walk-through Haskell" that is referred to. http://walk.northcol.org/haskell/adts/ In this way, al data types are generators that produce wooden structures according to a specific rule, and they correspond to one tree structure according to the rule.

The code has several problems, and the main one is what Bacco talked about in comments. How there are no keys in the command block the if will only selectively run the first line after if, the rest will always be executed. Lesson to be learned: always use keys, even if you only need a line and avoid confusion.There were some small problems, and others more serious like the fact of accepting typing of invalid values and letting leak memory of the streams.using static System.Console; using System.IO; namespace ConsoleApplication1 { public class Program { public static void Main(string[] args) { string[] names = new string[6]; WriteLine("Escolha:\n1 - adicionar\n2 - Visualizar\n 3 - Sair"); var valor = 0; if (!int.TryParse(ReadLine(), out valor)) WriteLine("Opção inválida"); if (valor == 1) { WriteLine("Escreva o nome do autor/grupo, nome do CD, ano de edição, nome da editora, total de tempo e número de faixas: "); for (int i = 0; i < 6; i++) names[i] = ReadLine(); using var sw = new StreamWriter(@"C:\Users\gabri\Desktop\trabalho.txt"); for (int i = 0; i < 6; i++) sw.WriteLine(names[i]); } if (valor == 2) { WriteLine("FICHEIRO .txt: \n"); using (var reader = File.OpenText(@"C:\Users\gabri\Desktop\trabalho.txt")) { string line; while ((line = reader.ReadLine()) != null) WriteLine(line); } ReadKey(); } if (valor == 3) WriteLine("Adeus"); } } } See "almost" https://ideone.com/7zgvDE .

You need to calculate the average outside for So:double _numero = 0; double _promedio = 0; double _contador = 0; Console.Clear(); Console.Write("Ingrese la cantidad de números que quiere promediar: "); _contador = double.Parse(Console.ReadLine()); for (int i = 0; i < _contador; i++) { Console.Write("Ingrese los números: "); _numero += double.Parse(Console.ReadLine()); } _promedio = _numero / _contador; Console.Write($"\nEl promedio es: {_promedio}") Console.Write("\n\nPulse Enter para salir..."); Console.ReadKey();

You can do this: public class Conteiner<T, U> where T : B<U> where U : A { T[] list; public T this[int index] { get { return list[index]; } set { list[index] = value; } } public void Set<K,N,M>(Conteiner<T, U> conteiner) where K : Conteiner<N, M> where N : B<M> where M : A { list[0] = conteiner[0]; } }
