ASP.NET MVC 4，爲什麼定義引擎沒有找到一個視圖

Question

我有一個類的自定義視圖引擎的 從這個類派生的2個引擎

public class MyViewEngine : RazorViewEngine 
{ 
    public string UIFramework { get; set; } 

    public MyViewEngine(string uiFramework) 
    { 
     UIFramework = uiFramework; 
     this.ViewLocationFormats = new[] 
     { 
      string.Format("~/Views/{0}/{{1}}/{{0}}.cshtml", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/{{1}}/{{0}}.vbhtml", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/{{1}}/{{0}}.aspx", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/{{1}}/{{0}}.ascx", this.UIFramework ?? string.Empty), 
     }; 
      this.PartialViewLocationFormats = new[] 
     { 
      string.Format("~/Views/{0}/Shared/{{0}}.cshtml", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/Shared/{{0}}.vbhtml", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/Shared/{{0}}.aspx", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/Shared/{{0}}.ascx", this.UIFramework ?? string.Empty), 
     }; 
     this.MasterLocationFormats = new[] 
     { 
      string.Format("~/Views/{0}/Shared/{{0}}.cshtml", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/Shared/{{0}}.vbhtml", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/Shared/{{0}}.aspx", this.UIFramework ?? string.Empty), 
      string.Format("~/Views/{0}/Shared/{{0}}.ascx", this.UIFramework ?? string.Empty), 
     }; 

    } 


} 

這些2個引擎在Global.asax中

ViewEngines.Engines.Clear(); 
ViewEngines.Engines.Add(new MyViewEngine("First")); 
ViewEngines.Engines.Add(new MyViewEngine("Second")); 

查找「第二個視圖引擎下」視圖沒有問題，但未找到「下」第一個視圖。我可以看到，在ViewEngineResult搜索位置是正確的，發動機應該看到我的看法;而我的觀點的名稱是正確的太多，但仍然ViewEngineResult在查看property.Folders結構返回null是相同的，當然兩個引擎

對不起，我的錯誤，這是與文件夾命名的問題。問題解決了
