MVC使用Exception过滤器自定义处理Action的的异常

1.继承FilterAttribute ,IExceptionFilter自定义处理

/// <summary>
/// 登录错误自定义处理
/// </summary>
public class LoginErrorFilter :FilterAttribute ,IExceptionFilter
{
    public string Title { get; set; }
    public LoginErrorFilter(string Title)
    {
        this.Title = Title;
    }
    public void OnException(ExceptionContext filterContext)
    {
        //获取出错描述
        string msg = this.Title + "时，";
        Exception ex = filterContext.Exception;
        msg += ex.Message;
        if (ex.InnerException != null)
        {
            msg += "，内部错误：" + ex.InnerException.Message;
        }
        //执行当前错误页面
        RouteData routeData = new RouteData();
        routeData.Values.Add("controller", "login");
        routeData.Values.Add("action", "error");
        routeData.Values.Add("msg", msg);
        IController one = new LoginController();
        one.Execute(new RequestContext(new HttpContextWrapper(HttpContext.Current), routeData));

        //返回状态500
        filterContext.HttpContext.Response.StatusCode = ;
        filterContext.ExceptionHandled = true;
        filterContext.Result = null;
    }
}

2.操作注释，使用处理

/// <summary>
/// QQ第三方登录处理
/// </summary>
/// <returns></returns>
[LoginErrorFilter("QQ登录处理")]
public ActionResult QQOperate()
{
    throw new Exception("错误003");
    return result;
}
