MVC3 Razor 根据不同页面使用不同Layout

_ViewStart.cshtml运行于每一Page前, 所以通常在这里先设置Layout

 

下面代码为特定的controller指定Index,Edit,Create的模板

即Index对应  _Index_Layout, Edit对应_Index_Layout...

 

@{

    var controller =  ViewContext.RouteData.Values["controller"].ToString().ToLower();

    var action = ViewContext.RouteData.Values["action"].ToString().ToLower();

 

    string[] lController = new string[] { "user", "news", "mail" };

    string[] lAction = new string[] { "index", "edit", "create" };

         

    if (lController.Contains(controller)){

        if (lAction.Contains(action))

        {

            Layout = "~/Views/Shared/_" + action  + "_Layout.cshtml";

        }else if (action == ""){

            Layout = "~/Views/Shared/_Index_Layout.cshtml";

        }

    }

     

}
