        DataTable dt = new DataTable();

        DataColumn ClassID = new DataColumn("ClassID", typeof(int));
        DataColumn ClassName = new DataColumn("ClassName", typeof(string));
        dt.Columns.Add(ClassID);
        dt.Columns.Add(ClassName);     

        DataRow dr = dt.NewRow();
        dr["ClassID"] = "1";
        dr["ClassName"] = "AAAA";
        DataRow dr2 = dt.NewRow();
        dr2["ClassID"] = "2";
        dr2["ClassName"] = "BBBB";
      
        dt.Rows.Add(dr);
        dt.Rows.Add(dr2);

        ds.Tables.Add(dt);
