设置或获取此代码类的访问特性。

命名空间： EnvDTE80
程序集： EnvDTE80（在 EnvDTE80.dll 中）

语法

声明
Property Access As vsCMAccess

vsCMAccess Access { get; set; }

property vsCMAccess Access {
    vsCMAccess get ();
    void set (vsCMAccess value);
}

abstract Access : vsCMAccess with get, set

function get Access () : vsCMAccess 
function set Access (value : vsCMAccess)

属性值

类型：vsCMAccess
一个 vsCMAccess 值。

备注

Access 属性返回一个常数，该常数指示实际的访问以及其他代码访问此代码类的可能方式。

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

[Visual Basic]

Sub AccessExample(ByVal dte As DTE2)
    ' 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(dte.ActiveDocument.Selection, TextSelection)
        Dim var As CodeVariable = _
            CType(sel.ActivePoint.CodeElement( _
            vsCMElement.vsCMElementVariable), CodeVariable)

        ' Display the CodeVariable's accessibility.
        Dim access As String
        Dim varAccess As vsCMAccess = var.Access
        Dim val As vsCMAccess
        For Each val In [Enum].GetValues(varAccess.GetType())
            If (val And varAccess) <> 0 Then
                access &= val.ToString() & vbCrLf
            End If
        Next

        MsgBox(var.Name & " has the following accessibility:" & _
            vbCrLf & vbCrLf & access)
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try
End Sub
