怎样将LIST中的数据绑定到GridView？

我的一个GridView操作文件,数据源是实体LIST,删改查功能都有了，你参考下 using System; using System.Collections; using System.Collections.Generic; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using lwf_MVC.CTRL;
