定义异常捕获类:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
    public class ExceptionAttribute : FilterAttribute, IExceptionFilter
    {
        public virtual void OnException(ExceptionContext filterContext)
        {
            string message = string.Format("消息类型：{0}<br>消息内容：{1}<br>引发异常的方法：{2}<br>引发异常源：{3}"
                , filterContext.Exception.GetType().Name
                , filterContext.Exception.Message
                 , filterContext.Exception.TargetSite
                 , filterContext.Exception.Source + filterContext.Exception.StackTrace
                 );
            
            //记录日志
            WriteLog.WriteInfo(message);

            //抛出异常信息
            filterContext.Controller.TempData["ExceptionAttributeMessages"] = message;

            //转向
            filterContext.ExceptionHandled = true;
            filterContext.Result = new RedirectResult(Globals.ApplicationDirectory + "/Error/ErrorDetail/");
        }
    }

　　

Mvc全局使用异常捕获类:

Global.asax.cs文件注册全局异常捕获类

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
　　filters.Add(new Models.ExceptionAttribute());

　　filters.Add(new HandleErrorAttribute());
}

实现其他全局过滤的思想同上.
