從ControllerContext對象獲取控制器的絕對路徑

我正在編寫一個MVC應用程序，並試圖用新類覆蓋RazorViewEngine。我想看看特定控制器嵌套在哪個文件夾中。從ControllerContext對象獲取控制器的絕對路徑

如果我的項目被設置爲：

>MyProject 
>>Controllers 
>>>SomeGroup 
>>>>AnotherGroup 
>>>>>MyTestController.cs

我想回到「〜\控制器\ SomeGroup \ AnotherGroup \ MyTestController.cs」;

我已經梳理了ControllerContext對象的任何路徑。我也試過：

HttpContext.Current.Server.MapPath("MyTestController.cs") 
Path.GetFullPath("MyTestController.cs"); 
Path.GetDirectoryName("MyTestController.cs"); 
Path.Combine(Directory.GetCurrentDirectory(), "MyTestController.cs"); 
new FileInfo("MyTestController.cs").FullName; 
new FileInfo("MyTestController.cs").Directory.FullName;

任何想法表示讚賞。謝謝！

編輯：我應該澄清一點。歡迎任何其他選項。我試圖將Views文件夾的文件夾結構與Controllers文件夾的文件夾結構相匹配。在RazorViewEngine中，我試圖從當前虛擬路徑和控制器路徑（我無法找到）創建視圖的實際路徑。我的類看起來像這樣。

public class MyRazorViewEngine :RazorViewEngine 
{ 
    public MyRazorViewEngine() 
     : base() 
{ 
    //Source: http://blog.thekfactor.info/posts/asp-net-mvc-custom-view-engines-using-the-razor-view-engine-as-the-base/ 
    ViewLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml","~/Views/%1/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml"}; 
    MasterLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml", "~/Views/%1/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" }; 
    PartialViewLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml","~/Views/%1/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" }; 
    FileExtensions = new string[] { "cshtml" }; 
} 

protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath) 
{ 
    string parentFolderPath = GetFolderNamesBetweenControllersFolderAndControllerFromContextObject(); 
    return base.CreateView(controllerContext, viewPath.Replace("%1", parentFolderPath), masterPath); 
} 

protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath) 
{ 
    string parentFolderPath = GetFolderNamesBetweenControllersFolderAndControllerFromContextObject(); 
    return base.CreatePartialView(controllerContext, partialPath.Replace("%1", parentFolderPath)); 
} 

protected override bool FileExists(ControllerContext controllerContext, string virtualPath) 
{ 
    string parentFolderPath = GetFolderNamesBetweenControllersFolderAndControllerFromContextObject(); 
    return base.FileExists(controllerContext, virtualPath.Replace("%1",parentFolderPath)); 
} 

}

我不想在這裏使用區域。我只是試圖在Views文件夾中建立一些層次結構。

假設您也使用默認路由到您的控制器，然後嘗試：

Request.CurrentExecutionFilePath

我試過HttpContext.Current.Request.CurrentExecutionFilePath和controllerContext.HttpContext.Request.CurrentExecutionFilePath。兩者都只是一個斜線。無內容。感謝您的建議。該代碼正在從RazorViewEngine繼承的類中調用。 – neonScarecrow

你錯誤地做這一點。你不需要返回控制器的文件位置......因爲它被編譯成DLL。

如果您正在嘗試擊中特定控制器MyTestController，則應該導航至以下URL http://www.example.com/MyTestController，並且該控制器的Index操作將會跳閘。

如果這不起作用，那麼您的默認路由有問題。你RouteConfig.cs應該有這樣的：

routes.MapRoute(
      name: "Default", 
      url: "{controller}/{action}/{id}", 
      defaults: new { controller = "Deposit", action = "Index", id = UrlParameter.Optional } 
     );
