Question

how to copy only the columns in a DataTable to another DataTable?

Answer 1

DataTable.Clone() should do the trick.

DataTable newTable = originalTable.Clone(); 

Answer 2

If only the columns are required then DataTable.Clone() can be used. With Clone function only the schema will be copied. But DataTable.Copy() copies both the structure and data

E.g.

DataTable dt = new DataTable(); dt.Columns.Add("Column Name"); dt.Rows.Add("Column Data"); DataTable dt1 = dt.Clone(); DataTable dt2 = dt.Copy(); 

dt1 will have only the one column but dt2 will have one column with one row.
