备注

在进行某些类型的编辑之后，代码模型元素（如类、结构、函数、特性、委托等）的值可能是非确定性的，这意味着不能指望它们的值总是保持不变。有关更多信息，请参见使用代码模型查找代码 (Visual Basic) 中的“代码模型元素的值可能会更改”一节。

示例

 Sub ParametersExample(ByVal dte As DTE2)

    ' Before running this example, open a code document from a project
    ' and place the insertion point inside a function.
    Try
        ' Retrieve the CodeFunction at the insertion point.
        Dim sel As TextSelection = _
            CType(dte.ActiveDocument.Selection, TextSelection)
        Dim fun As CodeFunction = _
            CType(sel.ActivePoint.CodeElement( _
            vsCMElement.vsCMElementFunction), CodeFunction)

        ' Display the function's parameters.
        Dim params As String
        Dim param As CodeParameter
        For Each param In fun.Parameters
            Dim start As TextPoint = param.GetStartPoint()
            Dim finish As TextPoint = param.GetEndPoint()

        MsgBox(fun.Name & " has the following parameters:" & _

    Catch ex As Exception
        MsgBox(ex.Message)
