如何將資料傳遞到 ASP.NET MVC 錯誤控制器以進行自訂錯誤處理？

protected void Application_Error(object sender, EventArgs e)
{
    Exception exception = Server.GetLastError();
    Response.Clear();

    HttpException httpException = exception as HttpException;

    if (httpException != null)
    {
        string action;

        switch (httpException.GetHttpCode())
        {
            case 404:
                action = "NotFound";
                break;
            case 500:
                action = "ServerError";
                break;
            default:
                action = "GenericError";
                break;
        }

        Server.ClearError(); // Clear the server-side error

        Response.Redirect(String.Format("~/Error/{0}?message={1}", action, Server.UrlEncode(exception.Message)));
    }
}

// GET: /Error/NotFound
public ActionResult NotFound()
{
    string message = Request.QueryString["message"];
    ViewBag.Message = message; // Or use a ViewModel
    return View();
}
