Why so complicated ?)

Try like this,

DataTable newTable = oldTable.Copy();
newTable.Columns.Remove("ColumnName");
You remove the unwanted columns here.

Here is the best Solution for your Question:

DataTable dt = new DataTable();
string [] column = {"Column1", "Column2"};
dt = DTItem.DefaultView.ToTable("dd", false, column);
//DTItem is the Existing Table and "dd" is the temporary tablename, u give whatever U want

Solution 2

Your collection is not a DataRow IEnumerable collection, so CopyToDataTable is not appearing
