Question

我有一个编写在ASP.NET MVC 5框架顶部的应用程序。

我创建了一个基本控制器，我的所有控制器都在其中。我的基本控制器看起来像这样

[Authorize]
public class BaseController : Controller
{
    protected IFlashManager Flash { get; set; }
    protected ICookie Cookie { get; set; }
    protected ICacheClient Cache { get; set; }

    protected override void Initialize(RequestContext requestContext)
    {
        base.Initialize(requestContext);

        Cookie = new CookieJar(requestContext.HttpContext);
        Flash = new FlashManager(TempData);
        Cache = new StackExchangeRedisCacheClient(new NewtonsoftSerializer());
    }
}

我想让全局Cookie和Cache对象可用于我的所有观看次数。

Microsoft已对User对象做了同样的事情。

我可以在不使用ViewBag或TempData的情况下执行此操作吗？

我创建了一个继承自WebViewPage<T>。

的新类

为您想要提供的每件新事物提供一个属性。
覆盖InitHelpers()以初始化这些属性。
将系统配置为使用您的班级而不是WebViewPage<T>

VB示例：

Imports System.Linq.Expressions

Public Class ProjectMvcViewPage(Of T)
    Inherits WebViewPage(Of T)


    Public Overrides Sub InitHelpers()

        MyBase.InitHelpers()

        Framework = New FrameworkHelper(Of T)(MyBase.ViewContext, Me)

    End Sub



    Public Overrides Sub Execute()

    End Sub



    Public Overloads Property Framework As FrameworkHelper(Of T)


End Class

Public Class ProjectMvcViewPage
    Inherits ProjectMvcViewPage(Of Object)

End Class




Public Class FrameworkHelper(Of T)
    Inherits HtmlHelper(Of T)

    Public Sub New(ByVal viewContext As ViewContext, ByVal viewDataContainer As IViewDataContainer)
        MyBase.New(viewContext, viewDataContainer)
    End Sub

    Public Sub New(ByVal viewContext As ViewContext, ByVal viewDataContainer As IViewDataContainer, ByVal routeCollection As RouteCollection)
        MyBase.New(viewContext, viewDataContainer, routeCollection)
    End Sub



    '   TODO:   Framework-specific methods

End Class

Public Class FrameworkHelper
    Inherits AkcHtmlHelper(Of Object)

    Public Sub New(ByVal viewContext As ViewContext, ByVal viewDataContainer As IViewDataContainer)
        MyBase.New(viewContext, viewDataContainer)
    End Sub

    Public Sub New(ByVal viewContext As ViewContext, ByVal viewDataContainer As IViewDataContainer, ByVal routeCollection As RouteCollection)
        MyBase.New(viewContext, viewDataContainer, routeCollection)
    End Sub

End Class

...并在Web.config中注册

<system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <!--<pages pageBaseType="System.Web.Mvc.WebViewPage">-->
    <pages pageBaseType="Project.ProjectMvcViewPage">
      <namespaces>
        <add namespace="System.Web.Mvc" />
        <add namespace="System.Web.Mvc.Ajax" />
        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Optimization"/>
        <add namespace="System.Web.Routing" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>

这可能有用。

HttpContext.Session.SetString("foo", "bar");
HttpContext.Session.GetString("foo");

如何创建全局变量并使其可用于ASP.NET MVC 5框架中的所有视图？
