如何为所有视图设置布局，基类和使用？(How to set layout, base class and usings for all views?)

如何为所有视图设置布局，基类和使用？(How to set layout, base class and usings for all views?)

在MVC 5中，我可以为“Views / Web.Config”中的所有视图设置默认基类和使用：

<system.web.webPages.razor> <pages pageBaseType="SomeCustomPageClass"> <namespaces> <add namespace="SomeNamespace" />

我还可以在“_ViewStart.cshtml”中为所有视图设置默认布局：

@{ Layout = "~/Views/Shared/SomeCustomLayout.cshtml"; }

我怎样才能在MVC 6中做到这些？

In MVC 5, I can set a default base class and usings for all views in "Views/Web.Config":

<system.web.webPages.razor> <pages pageBaseType="SomeCustomPageClass"> <namespaces> <add namespace="SomeNamespace" />

I can also set the default layout for all views in "_ViewStart.cshtml":

@{ Layout = "~/Views/Shared/SomeCustomLayout.cshtml"; }

How can I do any of these in MVC 6?

正如在CTP3 中的这个github问题中所报告的，没有办法通过配置来实现这一点。 但是，您可以使用自定义MvcRazorHost替换默认的MvcRazorHost：

public abstract class MyPage<T> : RazorPage<T> {/*...*/} public abstract class MyPage : RazorPage {/*...*/} public class MvcMyHost : MvcRazorHost { public MvcMyHost() : base(typeof(MyPage).FullName) { } } public class Startup { public void Configure(IBuilder app) { var configuration = new Configuration(); configuration.AddJsonFile("config.json"); configuration.AddEnvironmentVariables(); app.UseServices(services => { services.AddMvc(configuration); services.AddTransient<IMvcRazorHost, MvcMyHost>(); }); // etc... } }

不幸的是，由于编辑器总是使用原始的MvcRazorHost类，因此您无法使用此方法进行智能感知。

在vNext的alpha4 ，您所要求的所有内容（页面基本类型通过 - @inherits指令，使用，布局）将通过_ViewStart.cshtml支持， _ViewStart.cshtml所述。

As reported in this github issue in CTP3 there is no way of doing this via configuration. You can however replace the default MvcRazorHost with a custom one:

public abstract class MyPage<T> : RazorPage<T> {/*...*/} public abstract class MyPage : RazorPage {/*...*/} public class MvcMyHost : MvcRazorHost { public MvcMyHost() : base(typeof(MyPage).FullName) { } } public class Startup { public void Configure(IBuilder app) { var configuration = new Configuration(); configuration.AddJsonFile("config.json"); configuration.AddEnvironmentVariables(); app.UseServices(services => { services.AddMvc(configuration); services.AddTransient<IMvcRazorHost, MvcMyHost>(); }); // etc... } }

Unfortunately you don't get intellisense with this approach, since the editor always uses the original MvcRazorHost class.

In alpha4 of vNext everything you've asked for (page base type via - @inherits directive, usings, layout) will be supported via _ViewStart.cshtml as discussed here.
