How does ASP.NET MVC link views and controllers?
提问by Kristian Damian
What code does Visual Studio add (and where is it put?) when you right-click the controller method to link to the view?
当您右键单击控制器方法以链接到视图时，Visual Studio 添加了什么代码（以及它放在哪里？）？
How can one do this (link the controller & view) without Visual Studio?
如果没有 Visual Studio，如何做到这一点（链接控制器和视图）？

It is all by convention. You place your views in the Views/ControllerName folder for every controller and that's the default location for framework to look for. But it is not a must in any way.
这都是约定俗成的。您将视图放在每个控制器的 Views/ControllerName 文件夹中，这是框架要查找的默认位置。但这在任何情况下都不是必须的。
When in your controller you write
当你在你的控制器中写
return View();
Framework assumes you want the view with the same name as action name and looks for it in Views/Controller/ folder. Then Views/Shared.
Framework 假设您想要与操作名称同名的视图，并在 Views/Controller/ 文件夹中查找它。然后查看/共享。
But in your actions you can write
但在你的行动中你可以写
return View("ViewName");
Framework will look for a View named "ViewName" then in same folders.
框架将在相同的文件夹中查找名为“ViewName”的视图。
So default name for a view would be the name of action being executed. And that's a convention.
因此，视图的默认名称将是正在执行的操作的名称。这是一个约定。

By default asp.net MVC uses FormViewEngine, which is an implementation of IViewEngine. IViewEngine has got two methods called "FindView" and "FindPartialView" which actually locates the view file from "Views/Controller/" folder.
默认情况下，asp.net MVC 使用 FormViewEngine，它是 IViewEngine 的实现。IViewEngine 有两个名为“FindView”和“FindPartialView”的方法，它们实际上从“Views/Controller/”文件夹中定位视图文件。

Visual Studio will create a Folder (if it doesn't already exist) under ~/Views/{YourControllerName} and put your view in there. If it doesn't find it in there it will look in the ~/Views/Shared folder. If you want to manually create a view you need to add your page to one of those folders, preferably the ~/Views/{YourControllerName} folder. Hit up the NerdDinner tutorial to see this in action.
Visual Studio 将在 ~/Views/{YourControllerName} 下创建一个文件夹（如果它不存在）并将您的视图放在那里。如果在那里找不到它，它将在 ~/Views/Shared 文件夹中查找。如果您想手动创建视图，您需要将您的页面添加到这些文件夹之一，最好是 ~/Views/{YourControllerName} 文件夹。点击 NerdDinner 教程，看看它的实际效果。

Visual Studio uses templates to create the default views. The templates are located in the [Visual Studio Install Directory]\Common7\IDE\ItemTemplates[CSharp|VisualBasic]\Web\MVC\CodeTemplatesfolder.
Visual Studio 使用模板来创建默认视图。模板位于[Visual Studio 安装目录]\Common7\IDE\ItemTemplates[CSharp|VisualBasic]\Web\MVC\CodeTemplates文件夹中。
If you wish to create an MVC .ASPX page manually, you need to simply create a blank page and provide a Page directive with the following attributes:
如果您希望手动创建 MVC .ASPX 页面，您只需创建一个空白页面并提供具有以下属性的 Page 指令：
- Language ("C#" or "VB")
- MasterPageFile (default is ~/Views/Shared/Site.Master)
- Inherits (for strongly-typed models, use ViewPage<ModelClassName>; otherwise ViewPage)
- 语言（“C#”或“VB”）
- MasterPageFile（默认为~/Views/Shared/Site.Master）
- 继承（对于强类型模型，使用ViewPage< ModelClassName>；否则使用ViewPage）
Example:
例子：
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="ViewPage<ListCompanyManagerDetailsViewModel>" %>
For user controls (.ASCX), the same rules apply, except the MasterPageFile attribute is not used and you inherit from ViewUserControl.
对于用户控件 (.ASCX)，同样的规则适用，除了不使用 MasterPageFile 属性并且您从ViewUserControl继承。
Example:
例子：
<%@ Control Language="C#" Inherits="ViewUserControl<Contact>" %>
P.S. The reason that namespaces do not precede any of my class names is because I declared them in the section of my web.config.
PS 命名空间不在我的任何类名之前的原因是因为我在我的 web.config 部分声明了它们。
