ERROR CS0102 Type already contains a definition for the identifier, as is it possible?

I wonder if I'm the only one who's ever encountered this? In the class, two distinctly named properties, and the compiler thinks it's one thing. And the project is not going.
What can we do? The option of rename is not appropriate, as many legacy is tied to these names.

Comments on the matter indicated the correct solution.
The code should be written using the PascalCase style, which would eliminate future mistakes.

First, use it. HttpClient Right.readonly HttpClient client = new HttpClient(); public MyClass() // конструктор { // это вообще точно нужно? client.DefaultRequestHeaders.UserAgent.ParseAdd("VKAndroidApp/5.47.1-4248 (Android 9; SDK 28; armeabi-v7a; Android; ru; 1920x1080)"); } async Task<JObject> VkApiRequestAsync(string method, string parameter) { var values = new Dictionary<string, string> { ["access_token"] = (string)access_token }; using var content = new FormUrlEncodedContent(values); using var response = await client.PostAsync("https://api.vk.com/method/" + method + "?" + parameter + "&v=5.131", content); return JObject.Parse(await response.Content.ReadAsStringAsync()); } Second of all, we've got some type stuff.async Task CheckAsync() { JObject test = await VkApiRequestAsync("users.get", $"user_ids={user_id}"); await DisplayAlert("Тест", test["response"].ToString(), "Окей"); } Call it that way.await CheckAsync();

I think that's enough:int maior1 = 0, maior2 = 0; for(int i = 0; i < 5; i++) { System.out.println(" Digite números:"); int num = sc.nextInt(); if(num > maior1) { maior2 = maior1; maior1 = num; } else if(num > maior2) { maior2 = num; } } System.out.println(maior1 + " - " + maior2); See working on http://ideone.com/K9pAV0 .The essential differences for the original code are:if the entered number is greater than the first placed, the first placed goes to the second place (maior2 = maior1;).we use else to test if the number is second placed only if he is no longer the first place.O else only works if the first if it is not executed, after all, if the number is the first, we have already made the queue walk: the "ex-first" is moved to the second place, and the number entered takes the lead, so we do not need to take new test with the second placed.

Your problem is you're traveling the object XdSite.Models.Companis instead of the property vVentason the other hand, in Razor (at least me) the loop foreach I've been conflictive in some occasions, so I'd rather work with it. for@model XdSite.Models.Companis @using XdSite.Configuration; @using System.Collections.Generic; @{ ViewBag.Title = "Ventas"; Layout = "~/Views/Shared/View.cshtml"; } @for (int i = 0 ; i<Model.vVentas.Count() ; i++) { <li><a href="/Company/@Html.DisplayFor(x => x.vVentas[i].IdeInforme)/@Cleanurls.ToFriendlyUrl(@Html.DisplayFor(x => x.vVentas[i].Nombre))" title="@Html.DisplayFor(x => x.Ventas[i].Nombre)">@Html.DisplayFor(x => x.vVentas[i].Nombre)</a></li> } Sorry if there's any syntax error, I don't have visual studio right now.Greetings!

This table does not contain a single column.You need to define a http://pt.wikipedia.org/wiki/Chave_prim%C3%A1ria (column that differentiates one line from the others).When you use the interface buttons, phpMyAdmin performs the changes through the primary key of the line in question. For example, when you change the value of a field, it runs SQL as in the model below:UPDATE tabela SET campo = "valor" WHERE chave_primaria = "valor_da_chave_primaria" Since the table does not have a primary key, it does not make these buttons because it does not have to perform the operation only on that line. If it tries for another field, it can affect another line that has the same value.

There is no protection mechanism for a separate controlled assembly at NET. In Windows, however, there are other mechanisms for memory protection.Starting with Windows 10, https://docs.microsoft.com/en-us/windows/desktop/memory/trusted-execution It allows for isolated memory areas, so access to data in this area can only be obtained by a code loaded in the same area. Requires technical support from the processor (e.g. Intel Software Guard Extensions).For antiviral applications, starting with Windows 8.1, there is a mechanism https://docs.microsoft.com/en-us/windows/desktop/services/protecting-anti-malware-services- which limits access to the memory of a whole process. Any modules loaded in a secure service shall be signed by a special certificate.Applications for sound or video processing, starting with Windows Vista, can be used by Windows Media Foundation, which also provides a similar function to protect copyright (see). https://docs.microsoft.com/en-us/windows/desktop/medfound/protected-media-path )Where the above is not applicable, the annex may try to protect the same methods as the harmful software: the DLL injection into all processes and interception of memory functions (ReadProcessMemory et al.). The antiviruses in the old Windows are the same. However, this method is very unbelievable, because if two programmes attempt to apply it simultaneously, they are in conflict and unpredictable.Anyway, if you need real protection, at least you need to switch to an uncontrolled code. Also, you can always put a critical code in a remote service.

CookieContainer is a collection to which the necessary Cookie-type facilities can be added. You're just initializing her without adding anything to her.I mean, to send Cookie, we have to do something like:var container = new CookieContainer(); container.Add(new Cookie("Name_1", "Value")); container.Add(new Cookie("Name_2", "Value")); And then this collection can be asked.About getting it. ♪ ♪You have an answer from the server, I mean. HttpWebResponse response - The answer has that Cookie collection. Just take the right one from the normal collection or run the cycle.That's an example. https://msdn.microsoft.com/ru-ru/library/system.net.httpwebrequest.cookiecontainer(v=vs.110).aspx (to understand which values can be extracted):foreach (Cookie cook in response.Cookies) { Console.WriteLine("Cookie:"); Console.WriteLine("{0} = {1}", cook.Name, cook.Value); Console.WriteLine("Domain: {0}", cook.Domain); Console.WriteLine("Path: {0}", cook.Path); Console.WriteLine("Port: {0}", cook.Port); Console.WriteLine("Secure: {0}", cook.Secure); Console.WriteLine("When issued: {0}", cook.TimeStamp); Console.WriteLine("Expires: {0} (expired? {1})", cook.Expires, cook.Expired); Console.WriteLine("Don't save: {0}", cook.Discard); Console.WriteLine("Comment: {0}", cook.Comment); Console.WriteLine("Uri for comments: {0}", cook.CommentUri); Console.WriteLine("Version: RFC {0}", cook.Version == 1 ? "2109" : "2965"); // Show the string representation of the cookie. Console.WriteLine("String: {0}", cook.ToString()); }

The problem I had with my query was not specifically about the paths, nor could I not upload the files, but in the analysis of the portal, I had jumped in the html code to take into consideration sections that were in iframes. Once I identified them, I knew the correct navigation and provoke the desired behaviors.driver.FindElement(By.Id("navNodeAnchor_2_0")).Click(); Thread.Sleep(5000); driver.FindElement(By.Id("navNodeAnchor_2_0")).Click(); Thread.Sleep(5000); driver.SwitchTo().Frame(2); driver.SwitchTo().Frame(2); List <IWebElement> frames = new List<IWebElement>(driver.FindElements(By.TagName("input"))); IWebElement button = null; foreach (IWebElement frame in frames) { if (frame.GetAttribute("name").Equals("aaab.ValidaFacturaView.FileUploadCfd")) { button = frame; break; } } button.SendKeys(@"C:\Addendas\2020\07\16\B830440F-2803-4D03-B930-C890D1AF7C13.xml"); List<IWebElement> sended = new List<IWebElement>(driver.FindElements(By.TagName("a"))); foreach (IWebElement frame in sended) { if (frame.GetAttribute("id").Equals("aaab.ValidaFacturaView.ButtonCargarCFD")) { button = frame; break; } } button.Click(); Thread.Sleep(20000); string validacion = driver.FindElement(By.XPath("/html/body/form[1]/div/div/table/tbody/tr/td/div/div/div/table/tbody/tr/td/div/div/div/span/span/div/table/tbody/tr/td/div/span/span[1]/table/tbody/tr/td/table/tbody/tr[2]/td/div/table/tbody/tr/td[2]/span")).Text; if (validacion== "Factura en formato XML Aprobada") { driver.SwitchTo().DefaultContent(); driver.FindElement(By.Id("navNodeAnchor_2_2")).Click(); Thread.Sleep(5000); driver.FindElement(By.Id("navNodeAnchor_2_2")).Click(); Thread.Sleep(5000); driver.SwitchTo().Frame(2); driver.SwitchTo().Frame(2); List<IWebElement> framesSend = new List<IWebElement>(driver.FindElements(By.TagName("input"))); foreach (IWebElement frame in framesSend) { if (frame.GetAttribute("name").Equals("aaab.IngresaFacturaView.FileUploadCfd")) { button = frame; break; } } button.SendKeys(@"C:\Addendas\2020\07\16\B830440F-2803-4D03-B930-C890D1AF7C13.xml"); List<IWebElement> upload = new List<IWebElement>(driver.FindElements(By.TagName("a"))); foreach (IWebElement frame in upload) { if (frame.GetAttribute("id").Equals("aaab.IngresaFacturaView.ButtonCargarCFD")) { button = frame; break; } } button.Click();

Summary: internal is for the assembly range (i.e. only accessible from the code in the same .exe or .dll). Internal members are only accessible within the inheritance assembly (its type derived) or by class instance.Reference: http://www.dotnetbull.com/2013/10/public-protected-private-internal-access-modifier-in-c.html (Info in English)Expanded:Classes / utility methods or helpers you would like to access from many other classes within the same assembly, but those you want to make sure the code in other assemblies is not accessible.From the https://docs.microsoft.com/es-es/dotnet/csharp/language-reference/keywords/internal :A common use of internal access is in component-based development because it allows a group of components to cooperate privately without being exposed to the rest of the application code. For example, a framework for building graphical user interfaces could provide Control classes and Forms that cooperate using members with internal access. Since these members are internal, they are not exposed to the code used by the frame.You can also use the internal modifier along with the attribute https://msdn.microsoft.com/en-us/library/system.runtime.compilerservices.internalsvisibletoattribute.aspx assembly level to create "friends" assemblies that are granted special access to the inner classes of the destination assembly.This can be useful for the creation of unitary test sets that can then call the internal members of the set that will be tested. Of course, no other assembly is granted this level of access, so when you release your system, the encapsulation is maintained.
