Public Sub RemoveAt (index As Integer)

Int32

The index of the item to remove from the collection.

Examples

The following code example shows an implementation of the RemoveAt method. For an example of a complete implementation of the ISessionStateItemCollection interface, see the example provided in the ISessionStateItemCollection interface overview.

public void RemoveAt(int index)
{
  if (index < 0 || index >= this.Count)
    throw new ArgumentOutOfRangeException("The specified index is not within the acceptable range.");

  pItems.RemoveAt(index);
  pDirty = true;
}

 Public Sub RemoveAt(index As Integer) Implements ISessionStateItemCollection.RemoveAt 
   If index < 0 OrElse index >= Me.Count Then _
     Throw New ArgumentOutOfRangeException("The specified index is not within the acceptable range.")

   pItems.RemoveAt(index)
   pDirty = True
 End Sub

Remarks

In implementing the RemoveAt method, you should set the Dirty property to true to indicate values in the ISessionStateItemCollection implementation have been modified.

Your implementation of the RemoveAt method should throw an ArgumentOutOfRangeException exception if index is less than zero or is equal to or greater than ICollection.Count.
