傳回在 TextPoint 位置的程式碼項目。

命名空間:  EnvDTE
組件:  EnvDTE (在 EnvDTE.dll 中)

參數

屬性值

型別:EnvDTE.CodeElement
CodeElement 物件。

備註

如果指定的程式碼項目型別不在 TextPoint 位置,則 CodeElement 會傳回 Nothing。 CodeElement 是 TextPoint.Parent.Parent.ProjectItem.CodeModel.CodeElementFromPoint(TextPoint, <scope>) 的捷徑。

範例

Sub CodeElementExample(ByVal dte As DTE2)

    ' Before running this example, open a code document from a project
    ' and place the insertion point anywhere inside the source code.
    Try
        Dim sel As TextSelection = _
            CType(dte.ActiveDocument.Selection, TextSelection)
        Dim pnt As TextPoint = CType(sel.ActivePoint, TextPoint)

        ' Discover every code element containing the insertion point.
        Dim elems As String
        Dim elem As CodeElement
        Dim scope As vsCMElement
        For Each scope In [Enum].GetValues(scope.GetType())
            elem = pnt.CodeElement(scope)
            If IsNothing(elem) = False Then
                elems &= elem.Name & _
                    " (" & scope.ToString() & ")" & vbCrLf

    Catch ex As Exception
        MsgBox(ex.Message)

            CodeElement elem = pnt.get_CodeElement(scope);

            if (elem != null)

            + elems);
