ReadOnly Property CodeElement ( _
    Scope As vsCMElement _
) As CodeElement

CodeElement this[
    vsCMElement Scope
] { get; }

property CodeElement^ CodeElement[[InAttribute] vsCMElement Scope] {

abstract CodeElement : CodeElement

JScript 不支援索引屬性。

參數

Scope
型別：EnvDTE.vsCMElement
必要項。vsCMElement 常數，表示指定之種類的程式碼項目，項目中含有編輯器位置。

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 EditPoint 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
            End If
        Next

        MsgBox("The following elements contain the insertion point:" _
            & vbCrLf & vbCrLf & elems)
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try

        foreach (vsCMElement scope in Enum.GetValues(scopes.GetType()))
        {
            CodeElement elem = pnt.CodeElement(scope);

            if (elem != null)
