我所知道的程序错误提示方法

　　1、try catch

　　2、Application_Error

　　　　将如下代码添加到Global.asax下　　　　

        protected void Application_Error(object sender, EventArgs e)
        {
            Exception ex = Server.GetLastError();
            HttpException httpException = ex as HttpException;

            Response.Clear();
            Server.ClearError();

            #region 跳转一
            //var routeData = new RouteData();
            //routeData.Values["controller"] = "Error";
            //routeData.Values["action"] = "HttpError";
            //routeData.Values["message"] = ex.Message;

            //IController errorsController = new ErrorController();
            //var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
            //errorsController.Execute(rc);
            #endregion

            #region 跳转二
            Response.Redirect(String.Format("~/Error/{0}/?message={1}", "HttpError", ex.Message));
            #endregion
        }

　　3、RegisterGlobalFilters

　　　　1>Global.asax下的 FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

　　　　2>在web.config下的system.web 添加<customErrors mode="On"/>，跳转到Views>Shared>Error页面
