MVC的Filters（攔截過濾）的Error頁面，支持Ajax報錯

報錯攔截過濾到error頁面

    [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]    public class ExceptionAttribute : FilterAttribute, IExceptionFilter    {        /*報錯回到報錯頁Error*/        /*         *CreateTime：2013‎年‎3‎月‎18‎日         */        public void OnException(ExceptionContext filterContext)        {            //報錯回到報錯頁            string message = string.Format("消息類型：{0}<br>消息內容：{1}<br>引發異常的方法：{2}<br>引發異常源：{3}"                , filterContext.Exception.GetType().Name                , filterContext.Exception.Message                 , filterContext.Exception.TargetSite                 , filterContext.Exception.Source + filterContext.Exception.StackTrace                 );            filterContext.Controller.ViewData["ErrorMessage"] = message;//filterContext.Exception.Message + " 親！您犯錯了哦！";//得到報錯的內容            filterContext.Result = new ViewResult()//new一個url為Error視圖            {                ViewName = "Error",/*在Shard文件夾下的Error.cshtml*/                ViewData = filterContext.Controller.ViewData//view視圖的屬性中的viewdata被賦值            };            filterContext.ExceptionHandled = true;        }    }

修改上面功能，增加ajax錯誤判斷

/*報錯回到報錯頁Error*/        /*         *CreateTime：2013‎年‎3‎月‎18‎日         */        public void OnException(ExceptionContext filterContext)        {            //報錯回到報錯頁            string message = string.Format("消息類型：{0}<br>消息內容：{1}<br>引發異常的方法：{2}<br>引發異常源：{3}"                , filterContext.Exception.GetType().Name                , filterContext.Exception.Message                 , filterContext.Exception.TargetSite                 , filterContext.Exception.Source + filterContext.Exception.StackTrace                 );            filterContext.Controller.ViewData["ErrorMessage"] = message;//filterContext.Exception.Message + " 親！您犯錯了哦！";//得到報錯的內容            if (filterContext.HttpContext.Request.IsAjaxRequest())            {                filterContext.Result = new ContentResult()                {                    Content = "Error",                    ContentEncoding = Encoding.UTF8                };            }            else {                filterContext.Result = new ViewResult()//new一個url為Error視圖                {                    ViewName = "Error",/*在Shard文件夾下*/                    ViewData = filterContext.Controller.ViewData//view視圖的屬性中的viewdata被賦值                };            }            filterContext.ExceptionHandled = true;        }
