Assembly: Microsoft.Office.Interop.Word (in microsoft.office.interop.word.dll)
Use the CanvasItems property of either a Shape or ShapeRange object to return a CanvasShapes collection. To add shapes to a drawing canvas, use the following methods of the CanvasShapes collection: AddCallout, AddConnector, AddCurve, AddLabel, AddLine, AddPicture, AddPolyline, AddShape, AddTextbox, AddTextEffect, or BuildFreeform.
Use CanvasItems (index), where index is the name or the index number, to return a single shape in the CanvasShapes collection.
Each shape is assigned a default name when it is created. For example, if you add three different shapes to a document, they might be named Rectangle 2, TextBox 3, and Oval 4. Use the Name property to reference the default name or to assign a more meaningful name to a shape.
