您可以尝试......


DataColumn dc1 =新的DataColumn();
dc1.DataType = System.Type.GetType("System.Int32");
dc1.ColumnName ="ID";
dc1.AutoIncrement = true;
dc1.AutoIncrementSeed = 1;
dt.Columns.Add(dc1);


DataColumn dc =新的DataColumn();
dc.DataType = System.Type.GetType("System.String");
dc.Caption ="ReportName";
dc.ColumnName ="ReportName";
dt.Columns.Add(dc);

dt.Columns ["ReportName"].SetOrdinal(0);
dt.Columns ["ID"].SetOrdinal(1);

You can try this...


DataColumn dc1 = new DataColumn();
dc1.DataType = System.Type.GetType("System.Int32");
dc1.ColumnName = "ID";
dc1.AutoIncrement = true;
dc1.AutoIncrementSeed = 1;
dt.Columns.Add(dc1);


DataColumn dc = new DataColumn();
dc.DataType = System.Type.GetType("System.String");
dc.Caption = "ReportName";
dc.ColumnName = "ReportName";
dt.Columns.Add(dc);

dt.Columns["ReportName"].SetOrdinal(0);
dt.Columns["ID"].SetOrdinal(1);
