asp.net-mvc-2 - 我可以从 global.asax 重定向到 Controller 操作吗？

Question

当用户上传超过限制的文件时，我试图显示一个错误页面(参见 Catching "Maximum request length exceeded")

在 global.asax 中，我想重定向到 Controller 操作，所以像这样的东西但它不起作用？:

private void Application_Error(object sender, EventArgs e)
{
    if (GlobalHelper.IsMaxRequestExceededEexception(this.Server.GetLastError()))
    {
        this.Server.ClearError();
        return RedirectToAction("Home","Errorpage");
    }
}

像这样尝试:

protected void Application_Error()
{
    var exception = Server.GetLastError();
    // TODO: Log the exception or something
    Response.Clear();
    Server.ClearError();

    var routeData = new RouteData();
    routeData.Values["controller"] = "Home";
    routeData.Values["action"] = "ErrorPage";
    Response.StatusCode = 500;
    IController controller = new HomeController();
    var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
    controller.Execute(rc);
}
