MVC3动作记录机制

把网站重要的操作步骤记录下来，在ASP.NET MVC中，可以通过动作过滤器来实现。

首先在项目目录中新建一个"ActionFilter"目录，以集中管理所有的ActionFilter属性类，再新建一个ActionLogAttribute动作过滤器属性。

其中我的数据库表ActionLog结构如下图:

ActionLogAttribute类的代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using ChellonaMobileStationElectricity.Models;

namespace ChellonaMobileStationElectricity.ActionFilter
{
    public class ActionLogAttribute:ActionFilterAttribute
    {
        public string Description { get; set; }
        StationElectricEntities db;
        IMemberRepository _memberRepository;
        public ActionLogAttribute()
        {
            db = new StationElectricEntities();
            _memberRepository = new MemberRepository();
        }

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            ActionLog log = new ActionLog()
            {
                UserID = _memberRepository.GetMemberByAccount(filterContext.HttpContext.User.Identity.Name).UserID,
                Action = filterContext.RouteData.Values["controller"] + "." + filterContext.RouteData.Values["action"],
                ClientIP = filterContext.HttpContext.Request.UserHostAddress,
                DesCription = this.Description
            };
            db.AddToActionLog(log);
            db.SaveChanges();
        }
    }
}

然后，我们在Controller里面就可以使用了，如下：

    [HttpPost]
        [ChellonaMobileStationElectricity.ActionFilter.ActionLog(Description="新增用户")]
        public ActionResult Create(FormCollection collection)
        {
            if (ModelState.IsValid)
            {
                User user = new User();
                user.UserName = collection["UserName"];
                user.PassWord = _memberRepository.HashPassword(collection["PassWord"]);
                user.ChName = collection["ChName"];

查下数据库，已有数据，成功。
