將基本異常轉換為HttpException

Question

我正在開發ASP.Net應用程序，而我目前正努力處理異常。 我已經設法進行了適當的異常處理，但是我真的不知道如何處理不適合UI的內部錯誤。

void Application_Error(object sender, EventArgs e)
{
    Exception ex = Server.GetLastError();
    LogManager.GetCurrentClassLogger().Error(ex);
    Response.Clear();

    HttpException httpEx = ex as HttpException;
    if (httpEx == null)
    {
        switch(ex.GetType())
        {
            //Convert ex into httpexception 
            //with statuscode that depends on the exception type
        }
    }

    RouteData routeData = new RouteData();
    routeData.Values.Add("controller", "Error");
    routeData.Values.Add("action", "Handler");
    routeData.Values.Add("exception", httpEx);
    Server.ClearError();
    Response.TrySkipIisCustomErrors = true;

    var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
    var c = ControllerBuilder.Current.GetControllerFactory().CreateController(rc, "Error");
    c.Execute(rc);
}

與其嘗試將異常HttpException轉換為HttpException ，不如嘗試創建一個以原始異常作為內部異常的新HttpException ：

HttpException httpEx = new HttpException(500, msg, ex);
