如何在 C# .net 中的数据表中添加特定数量的行？

Question

I have 'n' number of rows in datatable1. Now i want add 'n' number of rows to datatable2.Its notable that two datatables are having different number of columns.Can anyone please help me with c# coding?

I have used following code but it doesn't work.

            datatable1 = feeCompBLL.getcommunity();
            foreach (DataRow drow in datatable1.Rows)
            {
                DataRow table2rows = datatable2.NewRow();
                datatable2.Rows.Add(table2rows );

            }

Answer 1

You, can use datatable2 = datatable1.Copy(); to do ur work. Hope it helps.

Answer 2

if the two datatables are having different number of columns you should specify the particular colum that you are trying to insert into the "datatable2"

eg

foreach (DataRow drow in datatable1.Rows)
{
  DataRow table2rows = datatable2.NewRow();                
  table2rows[columname] = drow[columnname];
  datatable2.Rows.Add(table2rows);            
}

that is you will have to assign the correct column name or column number to the new row.

Answer 3

To help you I need some info on the code; 1. does datatable2 have columns defined 2. What is FeeSetupRow

If columns are added already, I fee, datatable2.Rows.Add(FeeSetupRow) should be like datatable2.Rows.Add(table2rows).

If you want to copy also the data from datatable1 to datatable2 then you follow as kalyan specified.
