推荐答案

/add a column for serial no
 
DataSet ds = new DataSet();
DataColumn c = new DataColumn();
c.ColumnName = "Serial No.";
c.DataType = typeof(int);
ds.Tables.Add("TableA");        //add a table
ds.Tables[0].Columns.Add(c);             //add the column
ds.Tables[0].Columns[0].AutoIncrement = true;     //set the autoincrement (it starts from 0)
 
//this two lines add a blank row for the serial no '0' and remove it
//that way the serial number starts from 1 , instead of 0 for the fetched records.
ds.Tables[0].Rows.Add(0);
ds.Tables[0].Rows[0].Delete();
//after this you can upload the fetched records in a regular way (please refer "TableA" and dataset ds though) (see this codeguru.com link: http://www.codeguru.com/forum/showthread.php?t=452168 "  (How to display large number of rows in a DataGridView?)
