示例

Sub BasesExample(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 sel As TextSelection = _  
            CType(dte.ActiveDocument.Selection, TextSelection)  
        Dim cls As CodeClass = _  
            CType(sel.ActivePoint.CodeElement( _  
            vsCMElement.vsCMElementClass), CodeClass)

        Dim bases As String = ""

            vbCrLf & vbCrLf & bases)  
    Catch ex As Exception  
        MsgBox(ex.Message)  
    End Try

    // and place the insertion point inside a class definition.  
    try

        string bases = "";  
        foreach (CodeElement elem in cls.Bases)  
        {  
           bases += elem.FullName + Environment.NewLine;  
        }  

        MessageBox.Show(cls.Name + " has the following bases:" +   
            Environment.NewLine + Environment.NewLine + bases);  
    }  
    catch (Exception ex)  
    {  
        MessageBox.Show(ex.Message);  
    }  
}  

注解

基数是的超级类型 CodeElements 。 对于 Visual Basic 和 Visual c #,在集合中始终只有一个元素,但当代码类型为时除外 CodeInterface

备注

在进行了某些类型的编辑之后,代码模型元素(例如类、结构、函数、特性、委托等)的值可能变为非确定性的,这意味着不能确定它们的值始终保持不变。 有关详细信息,请参阅 "代码模型元素值在 使用代码模型查找代码时 可能发生变化" (Visual Basic) "。
