DataColumn dc = null;
//dt新增列
dc=dt.Columns.Add("id", Type.GetType("System.Int32")); //课件id
dc = dt.Columns.Add("coursewareNo", Type.GetType("System.String")); //课件编号
dc = dt.Columns.Add("coverPicture", Type.GetType("System.String")); //课件封面url
dc = dt.Columns.Add("imageUrl", Type.GetType("System.String")); //图片地址
dc = dt.Columns.Add("knowledges", Type.GetType("System.String")); //知识点

dc = dt.Columns.Add("uploadTime", Type.GetType("System.String")); //上传时间
dc = dt.Columns.Add("gradeName", Type.GetType("System.String")); //上传时间

 

DataRow dr = dt.NewRow();
dr["id"] = js["courseware"]["id"].ToString();
dr["coursewareNo"] = js["courseware"]["coursewareNo"].ToString();
