According to MSDN http://msdn.microsoft.com/ru-ru/library/ttw7t8t6.aspx :

The Operator foreach repeats a group of imported operators for each element of the set or collection of facilities that operate the interface System.Collections. IEnumerable or System.Collections.Generic.IEnumerable(Of T).

Just an example.

// Создаем массив и его инициализируем
string[] fruits = { "apple", "pear", "orange", "mandarin" };
// Проходим подряд по множеству значений массива и присваиваем fruit значение

// очередного элемента

foreach (string fruit in fruits) {

Console.WriteLine(fruit);

}

// Или пробегаем индексы от 0 до lenth - 1 и выводим значение элемента по индексу

for (int i = 0; i++; i < fruits.length) {

Console.WriteLine(fruits[i]);

}

For System.Random:Method Next() returns int and need to be clearly accommodating. byte:byte value = (byte)rnd.Next(); Or, in case of don't want to use the type-approach, the option with the method NextBytes:var buffer = new byte[1]; rnd.NextBytes(buffer); byte value = buffer[0]; Interval can be requested by overloading the method Nexthost two int Number: minValue (included) and maxValue (not including)Option to work for UnityEngine.Random:byte value = (byte)Random.Range(0, 256);

The name of the establishment you have at first $ee['Establecimiento']; and inside foreach You got it. $gg['Establecimiento'] Inside the foreach You can create a if<?php foreach ($establecimiento as $gg): ?> <? if ($ee['Establecimiento'] != $gg['Establecimiento']) ?> <option value="<?php echo $gg['IDEstablecimiento']; ?>"><?php echo $gg['Establecimiento']; ?></option> ?> <?php endforeach; ?> As you go through the establishments the condition that adds, it would be necessary to check if the name of the establishment you are traveling is different from the one you have, load the selectors available.

So I managed to solve the problem.public function extract(Occupation $occupation){ $occupations = Occupation::join('invoices', 'occupations.id', '=', 'invoices.occupation_id') ->leftJoin('payments', 'invoices.id', '=', 'payments.invoice_id') ->select('occupations.id', 'invoices.occupation_id', 'invoices.id as invoiceId', 'invoices.date_invoice', 'invoices.date_pay', 'invoices.ufir as invoiceUfir', 'payments.date_payment', 'payments.value') ->get(); return view('occupation/extract', compact('occupation', 'occupations')); } The Controller.@foreach($occupations as $o) <tr> <td>{{ $o->invoiceId }}</td> <td>{{ date('m/Y', strtotime($o->date_invoice)) }}</td> <td>{{ date('d/m/Y', strtotime($o->date_pay)) }}</td> <td>{{ number_format(($o->invoiceUfir), 2, ',', '.') }}</td> <td></td> <td></td> <td></td> <td>{{ date('d/m/Y', strtotime($o->date_payment)) }}</td> <td>{{ number_format($o->value, 2, ',', '.') }}</td> <td></td> </tr> @endforeach Blade.I specified in the Controller only what I needed in @foreach.

Since GridControl itself is only a submission container (View), to prohibit the editing of cells in the submission, you will issue a versionsBehavior. Editable in False when the shape is downloaded. In the button compression process, put the ops back to True. Look. https://documentation.devexpress.com/#WindowsForms/DevExpressXtraGridViewsBaseColumnViewOptionsBehavior_Editabletopic for more information.DevExpress grid doesn't have an IPA for access to specific cells as a standard gram. If editing of specific cells is to be prohibited, use it. https://documentation.devexpress.com/#WindowsForms/DevExpressXtraGridViewsBaseColumnView_ShowingEditortopic Ivant. In it, check the FocusedRowHandle and FocusedColumn performances.

I think this should serve you: public List<Order> ConsultaAObjetosAnidados(List<Order> input) { var res = from o in input from omd in o._OrderMetaData where omd.key == "trans" && omd.value select o; return res.ToList(); } Basic checks: [TestMethod] public void ConsultaAObjetosAnidados_Devuelve_0_1() { Order Order1 = new Order() { OrderNo = 1, _OrderMetaData = new List<OrderMetaData>() }; Order1._OrderMetaData.Add(new OrderMetaData() { id = 1, key = "no_trans", value = true }); List<Order> input = new List<Order>(); input.Add(Order1); Assert.IsTrue(_csharpfunctions.ConsultaAObjetosAnidados(input).Count == 0); } [TestMethod] public void ConsultaAObjetosAnidados_Devuelve_1_1() { Order Order1 = new Order() { OrderNo = 1, _OrderMetaData = new List<OrderMetaData>() }; Order1._OrderMetaData.Add(new OrderMetaData() { id = 1, key = "trans", value = true }); List<Order> input = new List<Order>(); input.Add(Order1); var res = _csharpfunctions.ConsultaAObjetosAnidados(input); Assert.IsTrue(res.Count == 1); }

foreach ($row['product_options'] as $option_id => $variant_id) { $option_name = db_get_fields("SELECT option_name FROM ?:product_options_descriptions WHERE option_id = ?i", $option_id, $variant_id, CART_LANGUAGE); $variant_name = db_get_fields("SELECT variant_name FROM ?:product_option_variants_descriptions WHERE variant_id = ?i", $variant_id, $option_id, CART_LANGUAGE); }; Here in the rewriting cycle, there will be only one outlet, no spins.There's got to be a mass if you need a mass. For example: foreach ($row['product_options'] as $option_id => $variant_id) { $option_name[] = db_get_fields("SELECT option_name FROM ?:product_options_descriptions WHERE option_id = ?i", $option_id, $variant_id, CART_LANGUAGE); $variant_name[] = db_get_fields("SELECT variant_name FROM ?:product_option_variants_descriptions WHERE variant_id = ?i", $variant_id, $option_id, CART_LANGUAGE); }; But it might be better to use an associated mass foreach to record the values or cycle for indexes with the mass. This is an example of the association: foreach ($row['product_options'] as $option_id => $variant_id) { $option_name = db_get_fields("SELECT option_name FROM ?:product_options_descriptions WHERE option_id = ?i", $option_id, $variant_id, CART_LANGUAGE); $variant_name = db_get_fields("SELECT variant_name FROM ?:product_option_variants_descriptions WHERE variant_id = ?i", $variant_id, $option_id, CART_LANGUAGE); $options[] = ['option_name' => $option_name, 'variant_name' => $variant_name]; }; It's got to do whatever it takes to process the body.

To go through an array in PHP, and we talk about arrays a little big, type 10 thousand iterations, the most efficient will be with foreach.A for with a i. a number It's the second fastest. Finally. slower is to go through the array with a for i ≤ count(array)Because every time it increases i call the count function of the array.I'll leave you an example of execution.$elements = array(); //// // Array de 10,000 elementos con string aleatorio //// for($i = 0; $i < 10000; $i++) { $elements[] = (string)rand(10000000, 99999999); } $time_start = microtime(true); //// // for //// for($i = 0; $i < count($elements); $i++) { } $time_end = microtime(true); $for_time = $time_end - $time_start; $time_start = microtime(true); //// // foreach //// foreach($elements as $element) { } $time_end = microtime(true); $foreach_time = $time_end - $time_start; echo "For tardo: " . number_format($for_time * 1000, 3) . "msn"; echo "Foreach tardo: " . number_format($foreach_time * 1000, 3) . "msn"; Departure: For late: 0.326msn Foreach tardo: 0.124msnNOTE: In case of changing the following linefor($i = 0; $i < count($elements); $i++) { } in this way:$contar = count($elements); for($i = 0; $i < $contar; $i++) { } The change is noticeable. And therefore end up having a better cycle performance for

This returning the error:Warning: Invalid argument supplied for foreach()because you are trying to iterate an element that is not array:$use[$i]['outrachave'] = 'some valor'; To resolve, you can make a condition and check if the element is an array:if ( is_array($a) ){ foreach ($a as $b) { print_r($b); echo "\n"; } } else { echo "Valor do elemento 'outrachave': {$a}\n"; } Full code$use = []; for ($i=0; $i < 2; $i++) { $use[$i]['outrachave'] = 'some valor'; for ($j=0; $j < 2 ; $j++) { for ($k=0; $k < 2 ; $k++) { $use[$i][$j][$k]= 'z'; } } } foreach ($use as $key) { echo "\n"; foreach ($key as $a) { if ( is_array($a) ) { foreach ($a as $b) { print_r($b); echo "\n"; } } else { echo "Valor do elemento 'outrachave': {$a}\n"; } } } Reference http://php.net/manual/pt_BR/function.is-array.php https://repl.it/@wellmotta/308748-ptstackoverflow

This specific problem is that you are accessing an element of array that does not exist, is accessing a number greater than the amount created elements, and need to validate this. It would be something like this:public void RegistrarModelo(Modelo modelo) => if(quantidadeModelos >= Modelos.Lenght) Modelos[quantidadeModelos++] = modelo; https://github.com/maniero/SOpt/blob/master/CSharp/Array/OutOfRange.cs .It may be that you prefer to do something if it is not possible to add the model. A common solution is to return a boolean if it was right or not for the consumer code to know if it could perform the operation.There are other conceptual errors in this code, but I won't even get into it (e.g. new Marca(quantidade); in the form used does not seem to make sense, but only who made it can guarantee). Has one of mechanism that will break your application and https://pt.stackoverflow.com/search?q=user%3A101%20tryparse . To the problem reported the answer is given and the suggestion to review everything you are doing and how you are learning too.Programming is understanding everything you're doing, especially understanding the mechanisms you're using. Don't use anything that doesn't completely dominate what it does, everything that can happen, how to solve every problem, you have to study every little detail of it before you use, because if you don't do this is creating random codes that can work by coincidence, and this is the worst that can happen to you, since if you make a mistake you know that there's something wrong that someone will fix for you doing on the internet, but if you don't make a mistake it can't be wrong you still be wrong and you it can't understand why you can't do anything.

Direct access to files in the folder is prohibited. This is the relevant section in the file. Views/web.config:<system.webServer> <handlers> <remove name="BlockViewHandler"/> <add name="BlockViewHandler" path="*" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" /> </handlers> </system.webServer> The Views in ASP.NET MVC are conceived primarily as a result of the work of the converter rather than as static pages. They're likely to expect data (model) for rendering, and it doesn't make any sense. HttpNotFoundHandler First of all, it has been introduced to prevent access to such View from outside, without a counter-aller challenge, because in the usual ASP. NET MVC of the annex, this treatment is likely to end in error due to the absence of a model.If you have a statistical file that needs to be handed directly to the client, put it in any other file. For example, Content♪ But most likely you were just wrong, and you turned to View directly, instead of summoning the appropriate method of counteraller.

Array.forEach() I wrote it inside Array.prototype.forEach() is called Array.prototype.forEach() What do I need to do?No. http://www.ecma-international.org/ecma-262/5.1/#sec-15.4.4.18 In the range Array.forEach not definedundefinedHome Array.forEach() This may cause an error. Project/environment Array.forEach() If it is executable, it is environment, library, etc. Array.forEach = Array.prototype.forEach; You may be able to do such things in advance (e.g. Firefox).Generally functions A() defined A.prototype.foo can be used directly or shown in the following sample code: new A() can be used from theA.foo See A.prototype.foo not forwarded.function A() {} A.prototype.foo = function() { console.log('foo called'); } var a = new A(); a.foo() // 呼べる! A.foo() // 呼べない (´・ω・`) orArray.prototype.forEach()andArray.forEach()Is it possible to process something that cannot be done?Consider JavaScript compatibility Array.prototype.forEach() Please use it.It is an extra talk, but it shows the call arguments for the function arguments is not an Array instance. That's why arguments.forEach() I can't use such as Array.prototype.forEach.call() You need to:function bar() { Array.prototype.forEach.call(arguments, function(n) { console.log(n); }); } bar(1, 2, 3); bar('a', 'b', 'c'); Mozilla(Firefox)Array.forEach() Comment Introduction of general-purpose simple notation ()
