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/>");
        }
