.NET MVC 获取 当前请求的 控制器/视图/区域 的名字

1)过滤器中的:

 public class CMSAttribute : FilterAttribute, IAuthorizationFilter
 {
     public void OnAuthorization(AuthorizationContext filterContext)
     {
         var controllerName = (filterContext.RouteData.Values["controller"]).ToString().ToLower();
         var actionName = (filterContext.RouteData.Values["action"]).ToString().ToLower();
         var areaName = (filterContext.RouteData.DataTokens["area"] == null ? "" : filterContext.RouteData.DataTokens["area"]).ToString().ToLower();

2)视图中的:

 @{
     //获取当前路由的区域名称
     var areaName = (ViewContext.RouteData.DataTokens["area"] == null ? "" : ViewContext.RouteData.DataTokens["area"]).ToString().ToLower();
     var actionName=ViewContext.RouteData.Values["action"].ToString().ToLower();
     var controllerName = ViewContext.RouteData.Values["controller"].ToString().ToLower();
 }

3)action中:

 string areaName=RouteData.DataTokens["area"].ToString().ToLower();
 string controllerName = RouteData.Values["controller"].ToString().ToLower();
 string actionName = RouteData.Values["action"].ToString().ToLower();
