column

The DataColumn to remove.

Use this overloaded version of the Remove method to remove a specified DataColumn object from the DataColumnCollection.

To remove a column at a specified index, use the RemoveAt method. You can also use the Clear method to remove all members of the collection at once.

The CollectionChanged event occurs when a column is successfully removed from the collection.

The following example uses the CanRemove method to test whether the last column in a DataColumnCollection can be removed. If so, the Remove method is called to remove the column.

private void RemoveColumn ( DataTable myTable ) {
   // get the DataColumnCollection.
   DataColumnCollection myColumns = myTable.Columns;
   DataColumn col = myColumns [ myColumns.Count -1 ];
   if ( myColumns.CanRemove ( col ) ) myColumns.Remove ( col );
}

Private Sub RemoveColumn ( Dim myTable As DataTable )
   ' get the DataColumnCollection.
   Dim myColumns As DataColumnCollection = myTable.Columns
   Dim col As DataColumn = myColumns ( myColumns.Count -1 );
   If myColumns.CanRemove ( col ) Then myColumns.Remove ( col );
End Sub
