自定义过滤器 
1.ASP.Net MVC内置四类过滤器分别为： IAuthorizationFilter IActionFilter IResultFilter IExceptionFilter 
2.关于过滤器的说明上述过滤器在使用上存在优先级，且依序从高到低可通过实现对应的接口创建自定义的过滤器 
3.自定义过滤器，示例(...)
 示例如下 
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]

    public class TraceAttribute : FilterAttribute, IActionFilter, IResultFilter

    {

        #region Properties

        public string LogName { get; set; }

        #endregion


        #region IActionFilter Members
