.NET MVC - 系統無法找到指定的路徑

Question

昨天我將我的網站從c：\ development \ project \部署到c：\ inetpub \ wwwroot \ virtualdir \（同一個pc）。它工作了一段時間，我可以通過http://computername/virtualdir/訪問該網站。

但今天早上，每個人都有一個錯誤：系統找不到指定的路徑。

無法找到指定的路徑是什麼？/virtualdir/bin /包含System.Web.Mvc.Dll程序集...另外，部署項目已將其標記爲依賴項，因此我在安裝過程中確實包含了它，它如何突然更改？

Answer 1

它找到一個System.Web.Mvc就好了，因爲你可以在堆棧跟蹤看到：

System.Web.Mvc.MvcHandler.ProcessRequest(HttpContextBase httpContext) +128 

什麼似乎正在發生的事情是ControllerTypeCache，當試圖列舉所有引用以查找控制器的assmeblies時，無法找到被另一個引用的程序集。

Answer 2

對於通過搜索來到此問題的其他人，可能會導致該錯誤消息的另一個配置錯誤是，如果您的虛擬目錄配置中沒有爲「asnet_isapi.dll」創建的通配符映射。

要創建映射：

• 打開虛擬目錄的屬性。
• 在「虛擬目錄」選項卡，單擊「配置」按鈕
• 點擊「插入」，並瀏覽到相應的.NET版本的「ASPNET_ISAPI.DLL」文件
• 取消選中「驗證文件是否存在」複選框
