Shape shape = (Shape)doc.GetChild(NodeType.Shape, 0, true);

Assert.AreEqual("6e182020-f460-11ce-9bcd-00aa00608e01", shape.OleFormat.Clsid.ToString());

Forms2OleControl oleControl = (Forms2OleControl)shape.OleFormat.OleControl;

// 某些 OLE 控件可能包含子控件，例如本文档中带有三个选项按钮的控件。
Forms2OleControlCollection oleControlCollection = oleControl.ChildNodes;

Assert.AreEqual(3, oleControlCollection.Count);

Assert.AreEqual("C#", oleControlCollection[0].Caption);
