命名空间： EnvDTE
程序集： EnvDTE（在 EnvDTE.dll 中）

语法

声明
ReadOnly Property Parent As Object

Object Parent { get; }

property Object^ Parent {
    Object^ get ();
}

abstract Parent : Object

function get Parent () : Object

属性值

类型：System.Object
CodeClass 对象的直接父对象。

备注

Parent 属性返回 CodeClass 对象的直接父对象。若要获取包含集合，请使用 Collection 属性。

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

Public Sub CodeClassExample(ByVal dte As DTE2) 
    ' Before running this example, open a code document from a
    ' project and place the insertion point inside a class definition.
    Try
        Dim objTextSel As TextSelection
        Dim objCodeCls As CodeClass
        Dim objCodeElem As CodeElement
        objTextSel = CType(dte.ActiveDocument.Selection, TextSelection)
        objCodeCls = CType(objTextSel.ActivePoint.CodeElement(vsCMElement.vsCMElementClass), CodeClass)
        ' Display the fullname of CodeClass object.
        MessageBox.Show(objCodeCls.FullName)
        ' Prove that the parent object of a CodeClass is a CodeElement.
        objCodeElem = CType(objCodeCls.Parent, CodeElement)
        ' Get access privilege for CodeClass.
        MessageBox.Show(objCodeCls.Access.ToString())
        ' Change access privilege for CodeClass objCodeCls.
        ' Note the change in access keyword in your code document.
        objCodeCls.Access = vsCMAccess.vsCMAccessPublic
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try
