試圖設置抓住所有未處理的異常，但它不工作

Question

我有一個剃刀網站運行良好，但偶爾我會得到一個未處理的異常。我想追查，但現在我想改變它，他們沒有看到這一點：

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Exception: Test 

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. 

這裏是我迄今爲止，但它並沒有抓住它。

的Global.asax.cs：

public static void RegisterRoutes(RouteCollection routes) 
{  
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); 
    routes.MapRoute("UnhandledExceptions", "Error", new { controller = "Error", action = "Index" }); 
    routes.MapRoute("Default", "{controller}/{action}/{id}", new { controller = "Account", action = "Logon", id = UrlParameter.Optional }); 
} 

我ErrorController.cs：

using System.Web.Mvc; 

namespace SuburbanCustPortal.Controllers 
{ 
    public class ErrorController : Controller 
    { 
    public ActionResult Index() 
    { 
     return View("Error"); 
    } 
    } 
} 

我的測試代碼來生成一個錯誤：

public ActionResult Test() 
{ 
    throw new Exception("Test"); 
} 

我這是我的web.config：

<customErrors mode="On" > 
    <error statusCode="403" redirect="~/Error"/> 
    <error statusCode="404" redirect="~/Error"/> 
    <error statusCode="500" redirect="~/Error"/> 
</customErrors> 

我錯過了什麼？

======編輯＃1 ======

我做每邁克的回答的變化，改變了web.config中：

<customErrors mode="On" defaultRedirect="~/Error/"> 
</customErrors> 

我得到此消息：

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Exception: Test 

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. 

Stack Trace:

    System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +375 

這是我在嘗試運行上述測試時得到的異常。

Answer 1

根據你的代碼，說你正在嘗試做的，你想要的是這樣的：

<customErrors mode="On" defaultRedirect="~/Error/"> 
</customErrors> 

Answer 2

捕捉任何未處理的異常，請使用以下構建您的Global.asax：

public class MvcApplication : System.Web.HttpApplication 
{ 
    public MvcApplication() 
    { 
    Error += MvcApplication_Error; 
    } 

    private void MvcApplication_Error(object sender, EventArgs e) 
    { 
    Exception exception = application.Server.GetLastError(); 
    ...process exception... 

    // clear the exception from the server 
    application.Server.ClearError(); 
    } 
}
