Asp .Net MVC中常用过滤属性类

         /// <summary>
     ///
     /// </summary>
     public class AjaxOnlyAttribute : ActionFilterAttribute
     {
         /// <summary>
         /// Called by the ASP.NET MVC framework before the action method executes.
         /// </summary>
         /// <param name="filterContext">The filter context.</param>
         public override void OnActionExecuting(ActionExecutingContext filterContext)
         {
             if (!filterContext.HttpContext.Request.IsAjaxRequest())
             {
                 filterContext.Result = new ContentResult() { Content = "只支持Ajax方法调用。", ContentEncoding = Encoding.UTF8, ContentType = "text/html" };
                 //new HttpNotFoundResult();
             }
             base.OnActionExecuting(filterContext);
         }

只允许通过Ajax调用

         /// <summary>
     /// 自定义模板页面
     /// </summary>
     public class LayoutAttribute : ActionFilterAttribute
     {
         private readonly string _masterName;
         public LayoutAttribute(string masterName)
         {
             _masterName = masterName;
         }
         /// <summary>
         /// 页面渲染结束后执行
         /// </summary>
         /// <param name="filterContext"></param>
         public override void OnActionExecuted(ActionExecutedContext filterContext)
         {
             base.OnActionExecuted(filterContext);
             var result = filterContext.Result as ViewResult;
             if (result != null)
             {
                 result.MasterName = _masterName;
             }
         }
     }

设置公共母板页面

         /// <summary>
     /// 页面标题
     /// </summary>
     public class PageTitleAttribute : ActionFilterAttribute
     {
         private readonly string _pageTitle;
         public PageTitleAttribute(string pageTitle)
         {
             _pageTitle = pageTitle;
         }
         /// <summary>
         /// 页面渲染结束后执行
         /// </summary>
         /// <param name="filterContext"></param>
         public override void OnActionExecuted(ActionExecutedContext filterContext)
         {
             base.OnActionExecuted(filterContext);
             var result = filterContext.Result as ViewResult;
             if (result != null)
             {
                 result.ViewBag.Title = _pageTitle;
             }
         }
     }

设置Action页面标题

     [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false)]
     public class AuthorizeFilterAttribute : ActionFilterAttribute
     {
         // OnActionExecuted 在执行操作方法后由 ASP.NET MVC 框架调用。
         // OnActionExecuting 在执行操作方法之前由 ASP.NET MVC 框架调用。
         // OnResultExecuted 在执行操作结果后由 ASP.NET MVC 框架调用。
         // OnResultExecuting 在执行操作结果之前由 ASP.NET MVC 框架调用。
         public override void OnActionExecuting(ActionExecutingContext filterContext)
         {
             //DoSomething();
         }
     }        

设置页面访问权限验证
