自定义asp.net mvc Filter 过滤器

1新建一个mvc项目：如图

2、主要创建下面一些类文件

1、utility目录 放置自定义的过滤器

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace WebAppTest.utility
{
    //自定义LogActionFilter继承ActionFilterAttribute
    public class LogActionFilter : ActionFilterAttribute
    {
        /// <summary>
        /// 重写ActionFilterAttribute中的方法
        /// </summary>
        /// <param name="filterContext"></param>
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            Log("OnActionExecuting", filterContext.RouteData);
        }

        public override void OnActionExecuted(ActionExecutedContext filterContext)
        {
            Log("OnActionExecuted", filterContext.RouteData);
        }

        public override void OnResultExecuting(ResultExecutingContext filterContext)
        {
            Log("OnResultExecuting", filterContext.RouteData);
        }
        public override void OnResultExecuted(ResultExecutedContext filterContext)
        {
            Log("OnResultExecuted", filterContext.RouteData);
        }
        //日志输出
        private void Log(string methodName, RouteData routeData)
        {
            var controllerName = routeData.Values["controller"];
            var actionName = routeData.Values["action"];
            var message = String.Format("{0} controller:{1} action:{2}", methodName, controllerName, actionName);
            Debug.WriteLine(message, "Action Filter Log");
        }

    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http.Controllers;
using System.Web.Http.Filters;
using System.Web.Mvc;

namespace WebAppTest.utility
{
    public class CustomerFilterAttribute : System.Web.Mvc.ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            //base.OnActionExecuting(filterContext);
            filterContext.HttpContext.Response.Write("开始时间:" + DateTime.Now.ToString() + "<br/>");
        }
        public override void OnActionExecuted(ActionExecutedContext filterContext)
        {
            //base.OnActionExecuted(filterContext);
            var controllerName = filterContext.RouteData.Values["controller"].ToString();
            var actionName = filterContext.RouteData.Values["action"].ToString();
            filterContext.HttpContext.Response.Write("结束时间:" + DateTime.Now.ToString() + "<br/>");
            filterContext.HttpContext.Response.Write("controller:" + controllerName + ",action:" + actionName);
        }
    }
}
