MVC使用Exception过滤器自定义处理Action的的异常

/// <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 = 500;
filterContext.ExceptionHandled = true;
filterContext.Result = null;
}
}

/// <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;
}
