Asp.Net MVC如何獲取錯誤代碼

Question

我使用asp.net mvc和下面的代碼來返回異常說明並將其存儲在會話中。我需要幫助找出像500 403 404等異常的錯誤代碼等。我該怎麼做？

這是我如何在會話中存儲錯誤消息。 System.Web.HttpContext.Current.Session [「errorMessage」] = filterContext.Exception.Message.ToString（）;

public override void OnException(System.Web.Mvc.ExceptionContext filterContext) 
     { 
      ProcessResult processResult = new ProcessResult(); 

      //If the exeption is already handled we do nothing 
      if (filterContext.ExceptionHandled) 
      { 
       return; 
      } 
      else 
      { 
       var controllerName = (string)filterContext.RouteData.Values["controller"]; 
       var actionName = (string)filterContext.RouteData.Values["action"]; 
       var model = new HandleErrorInfo(filterContext.Exception, controllerName, actionName); 
       processResult.Controller = controllerName; 
       processResult.Action = actionName; 
       processResult.ExceptionMessage = filterContext.Exception.Message; 
       System.Web.HttpContext.Current.Session["errorMessage"] =      filterContext.Exception.Message.ToString(); 
       processResult.StackTrace = filterContext.Exception.StackTrace; 
       processResult.Source = filterContext.Exception.Source; 

      } 
      //Mark the exception as handled 
      filterContext.ExceptionHandled = true; 
     } 
    }

檢查以查看Exception是否是HttpException。然後按照這種方式施放它並獲取狀態代碼。

if (filterContext.Exception is HttpException) 
{ 
    var statusCode = ((HttpException)filterContext.Exception).GetHttpCode(); 
}
