DataColumnCollection.RemoveAt Method

Removes the column at the specified index from the collection.

Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)

public void RemoveAt(
	int index
)

Parameters

index
Type: System.Int32

The index of the column to remove.

ExceptionCondition
ArgumentException

The collection does not have a column at the specified index.

If the collection is successfully changed by adding or removing columns, the CollectionChanged event occurs.

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
