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();
     }

}
