Unable to Copy datacolumn from one data table to another

Question

How can I copy 1 data column from 1 data table to a new datatable. When I try to do it, I get the error Column \'XXX\' already belongs to another DataTable.?

Answer 1

No looping required , Refer this , Hope this should solve your problem...

DataTable dt = new DataTable(); 
//fill the dt here 
DataTable dt2 = new DataTable(); 
string[] strCols = {"Column Name to copy"}; 
dt2 = dt.DefaultView.ToTable("newTableName", false, strCols);
