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

The problem is caused by the c# can not reuse the object instance created and uses it on multiples DataTables. For this it is necessary to create a new object DataCollumn for each loop iteration.

foreach (DataTable table in DATASET.Tables)
{
    DataColumn yourDataCollumn = new DataColumn("Name of DataCollumn", typeof(Your data type));
    // your logic here
}

Hope it's help...
