Asp.Net MVC3(二)过滤器定义

定义过滤类:

public class TestFilter : ActionFilterAttribute
    {
        /// <summary>
        /// 行为执行前
        /// </summary>
        /// <param name="filterContext"></param>
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            //ToDoing
            if (filterContext.ActionDescriptor.ActionName.ToLower() == "testList".ToLower())
            {
               if (true)
               {
                        filterContext.HttpContext.Response.Write("您没有权限操作！");
                        filterContext.HttpContext.Response.End();
               }
            }
            base.OnActionExecuting(filterContext);
        }
    }

控制器中使用:

[TestFilter]

public class AuditPayExpenseController : Controller     

{

     public ActionResult testList(int? pagerIndex, FormCollection collenct)
     {

        return View();
     }

}
