  The Shape to remove from the ShapeCollection.

Remarks

When a Shape is removed from the control collection, all subsequent shapes are moved up one position in the collection.

You can also remove a Shape by using the RemoveAt method, or remove all shapes by using the Clear method.

To add new Shape objects to the collection, use the Add or AddRange method.

Notes to Inheritors

When overriding Remove in a derived class, be sure to call the Remove method of the base class to guarantee that the shape is removed from the collection.

Examples

The following example demonstrates how to use the Remove method to remove a Shape from a form if it is a member of the form's ShapeCollection. This example requires that you have at least two OvalShape controls on a form.

Private Sub Form1_Click() Handles Me.Click
    Dim canvas As ShapeContainer
    ' Get the ShapeContainer.
    canvas = OvalShape1.Parent
    ' If OvalShape2 is in the same collection, remove it.
    If canvas.Shapes.Contains(OvalShape2) Then
        canvas.Shapes.Remove(OvalShape2)
    End If
End Sub

private void form1_Click(object sender, System.EventArgs e)
{
    ShapeContainer canvas;
    // Get the ShapeContainer.
    canvas = ovalShape1.Parent;
    // If OvalShape2 is in the same collection, remove it.
    if (canvas.Shapes.Contains(ovalShape2))
    {
        canvas.Shapes.Remove(ovalShape2);
    }
}
