public:
void RemoveAt(int index);
public void RemoveAt (int index);
member this.RemoveAt : int -> unit
Public Sub RemoveAt (index As Integer)
- index
- Int32
The index of the column to remove.
The collection does not have a column at the specified index.
The following example first uses the Contains method to determine whether a particular column is found in the collection. If it is found, the CanRemove method tests whether the column can be removed. If so, the column is removed with the RemoveAt method.
Private Sub RemoveColumnAtIndex(thisIndex As Integer)
' Get the DataColumnCollection from a DataTable in a DataSet.
Dim columns As DataColumnCollection = _
DataSet1.Tables("Orders").Columns
If columns.CanRemove(columns(thisIndex)) Then
columns.RemoveAt(thisIndex)
End If
End Sub
If the collection is successfully changed by adding or removing columns, the CollectionChanged event occurs.
