C＃mvc4 ViewResult如何設置控制器和區域？

Question

public override void OnException(ExceptionContext filterContext) { 

    string controllerName = (string) filterContext.RouteData.Values["controller"]; 
    string actionName = (string) filterContext.RouteData.Values["action"]; 
    // Preserve old ViewData here 
    var viewData = new ViewDataDictionary<HandleErrorInfo>(filterContext.Controller.ViewData); 
    // Set the Exception information model here 
    viewData.Model = new HandleErrorInfo(filterContext.Exception, controllerName, actionName); 
    filterContext.Result = new ViewResult { ViewName = this.View, MasterName = this.Master, ViewData = viewData, TempData = filterContext.Controller.TempData }; 
    filterContext.ExceptionHandled = true; 
    filterContext.HttpContext.Response.Clear(); 
    //filterContext.HttpContext.Response.StatusCode = 500; 
    filterContext.HttpContext.Response.TrySkipIisCustomErrors = true; 

，但我得到的錯誤：

{System.InvalidOperationException: The view 'Error' or its master was not found or no view engine supports the searched locations. The following locations were searched: 
xxxxxxxx 

，但我的位置不是搜索。錯誤方法在MyErrorController中。我怎樣才能明確設置控制器（MyErrorController）

我的路徑必須是〜/地區/公共/瀏覽/ MyError/Error.ascx

"area" -> "Public" 
"controller", "MyError" 
"action" -> "Error";

之前設置filterContext.Result，嘗試添加下面幾行：

filterContext.RouteData.DataTokens["area"] = "Public"; 
filterContext.RouteData.Values["controller"] = "MyError"; 
filterContext.RouteData.Values["action"] = "Error";
