从visual studio加载项访问本地变量

Question

我正在尝试编写一个visualstudio插件。以下代码用于在visualstudio代码窗口中显示所选文本的全局变量或类名或函数名。但是，它不会显示函数内部定义的变量。如何修改此项以显示局部变量？

'Call this function inside OnConnection event of the addin
Sub displayCodeElementName()
    ' Before running this example, open a code document from a project
    ' and place the insertion point inside a variable definition.
    Try
        ' Retrieve the CodeVariable at the insertion point.
        Dim sel As TextSelection = _
            CType(applicationObject.ActiveDocument.Selection, TextSelection)
        Dim var As CodeVariable2 = CType(sel.ActivePoint.CodeElement(vsCMElement.vsCMElementVariable), CodeVariable2)
        ' Display the code element name
            MsgBox(var.Name & " is the name.")
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try
End sub

微软似乎没有公开底层API。我做了一项研究，却找不到访问函数定义中代码元素的方法。
