This example illustrates how to remove a shape.
You can remove an item from the ShapeCollection using the ShapeCollection.RemoveAt method.
If a target item is a Chart or Picture object, the ShapeCollection.RemoveAt method call removes this shape from two collections: ShapeCollection and ChartCollection or PictureCollection, respectively.
Call the Shape.Delete method to remove a Shape object directly. The code sample below shows how to remove all connectors from a worksheet:
foreach (Shape shape in worksheet.Shapes)
if (shape.ShapeType == ShapeType.Connector)
