DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("ImageUrl1", typeof(string))); dt.Columns.Add(new DataColumn("ImageUrl2", typeof(string))); DataRow dr = dt.NewRow();//
dr["ImageUrl1"] = "../Img/a.jpg";
dt.Rows.Add(dr); dr = dt.NewRow();
dr["ImageUrl2"] = "../Img/b.jpg";
dt.Rows.Add(dr); rep1.DataSource = dt;//给Repeater数据源
rep1.DataBind();//绑定数据源
}问题是我的Img的传过去的值有啊
为什么在show()里面是未定义的值呢
DataRow dr = dt.NewRow();
dr["ImageUrl1"] = "../Img/a.jpg";
dr["ImageUrl2"] = "../Img/b.jpg";
dt.Rows.Add(dr);
