從controllerContext獲取viewModel MVC

Question

我需要從類ControllerContext獲取我的viewmodel。我需要閱讀一些viewmodel ControllerContext的屬性。我怎樣才能做到這一點？？

using System; 
using System.Web; 
using System.Web.Routing; 
using System.Web.WebPages; 

namespace System.Web.Mvc 
{ 
    // Summary: 
    //  Encapsulates information about an HTTP request that matches specified System.Web.Routing.RouteBase 
    //  and System.Web.Mvc.ControllerBase instances. 
    public class ControllerContext 
    { 
     // Summary: 
     //  Initializes a new instance of the System.Web.Mvc.ControllerContext class. 
     public ControllerContext(); 
     // 
     // Summary: 
     //  Initializes a new instance of the System.Web.Mvc.ControllerContext class 
     //  by using the specified controller context. 
     // 
     // Parameters: 
     // controllerContext: 
     //  The controller context. 
     // 
     // Exceptions:

     //  The request context. 
     // 
     // controller: 
     //  The controller. 
     // 
     // Exceptions: 
     // System.ArgumentNullException: 
     //  One or both parameters are null. 
     public ControllerContext(RequestContext requestContext, ControllerBase controller); 
     // 
     // Summary:

     public ControllerContext(HttpContextBase httpContext, RouteData routeData, ControllerBase controller); 

     // Summary: 
     //  Gets or sets the controller.

     // 
     // Summary: 
     //  Gets or sets the HTTP context. 
     // 
     // Returns: 
     //  The HTTP context. 
     public virtual HttpContextBase HttpContext { get; set; } 
     // 
     // Summary: 
     //  Gets a value that indicates whether the associated action method is a child 
     //  action. 
     //

     public virtual bool IsChildAction { get; }

Answer 1

嘗試：

ControllerContext.Controller.ViewData.Model 

目前尚不清楚時正是你需要獲取從上下文的數據，但你必須認識到，ViewModel返回到View只有在後可用0事件（在ActionFilter中同樣的方法）。

Answer 2

假設我明白的問題，可以用點號訪問ControllerContext的屬性：

ControllerContext.<PropertyName>
