在MVC App_Code显示帮助器中使用C＃6使用静态语法 [英] Using C# 6's using static syntax in MVC App_Code display helpers

问题描述

是否可以在MVC 5的App_Code的显示助手中使用C＃6.0的新使用静态符号？

Is it possible to use C# 6.0's new "using static" notation inside of display helpers in App_Code in MVC 5?

我尝试这样做，但是它

我创建了一个静态帮助器类以在App_Code中公开UrlHelper和HtmlHelper。我希望将其包含在 using static语法中，以便像使用文件具有ViewPage基类一样使用类的属性。

I created a static helper class to expose UrlHelper and HtmlHelper within App_Code. I was hoping to include it with the "using static" syntax in order to use the properties of the class as I would as if the file had a ViewPage base class.

@using static Example.Core.ViewHelper

@helper ExampleUsingUrl() {
    @Url.Action("Index", "Home")
}

使用这样的ViewHelper。

With a ViewHelper looking like this.

namespace Example.Core
{
    public static class ViewHelper
    {
        public static HtmlHelper Html { get; } = new HtmlHelper(new ViewContext(), new ViewDataContainer());
        public static UrlHelper Url => new UrlHelper(HttpContext.Current.Request.RequestContext, RouteTable.Routes); 
    }

    public class ViewDataContainer : IViewDataContainer
    {
        public ViewDataDictionary ViewData
        {
            get
            {
                return new ViewDataDictionary();
            }
            set
            {

            }
        }
    }
}

此功能还不能用于视图吗？我正在使用Visual Studio 2015，MVC 5，.NET 4.6.1和C＃6.0。

Is this feature not available for views yet? I am using Visual Studio 2015, MVC 5, .NET 4.6.1 and C# 6.0.

推荐答案

在MVC5中这是不可能的但是MVC6。

This is not possible in MVC5 but MVC6.

请参见代码更改以支持在MVC6中使用静态： https://github.com/aspnet/Razor/commit/1879ac642754b5f84e6055580e6fc60e13fa2100

See code change for supporting using static in MVC6: https://github.com/aspnet/Razor/commit/1879ac642754b5f84e6055580e6fc60e13fa2100
