datatable动态添加，及填充数据

 DataTable tblDatas = new DataTable("Datas");

        tblDatas.Columns.Add("ID", Type.GetType("System.Int32"));

        tblDatas.Columns[0].AutoIncrement = true;

        tblDatas.Columns[0].AutoIncrementSeed = 1;

        tblDatas.Columns[0].AutoIncrementStep = 1;//自增列

        tblDatas.Columns.Add("Product", Type.GetType("System.String"));

        tblDatas.Columns.Add("Version", Type.GetType("System.String"));

        tblDatas.Columns.Add("Description", Type.GetType("System.String"));

        DataRow row;

        for (int i = 0; i <= 3; i++)

        {

            row = tblDatas.NewRow();

            row["Product"] = "789";

            row["Version"] = "Item ";

            row["Description"] = "567";

            tblDatas.Rows.Add(row);

        }



        foreach (DataRow dr in tblDatas.Rows)

        {

            Response.Write(dr["Version"].ToString() + "<br/>");

        }
