CodeClass.ImplementedInterfaces 属性

获取由 CodeClass 对象实现的接口的集合。

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

语法

声明
ReadOnly Property ImplementedInterfaces As CodeElements
CodeElements ImplementedInterfaces { get; }
property CodeElements^ ImplementedInterfaces {
    CodeElements^ get ();
}
abstract ImplementedInterfaces : CodeElements
function get ImplementedInterfaces () : CodeElements

属性值

类型:EnvDTE.CodeElements
一个 CodeElements 集合。

备注

ImplementedInterfaces 返回一个 CodeElements 集合,每个元素的类型均为 vsCMElementInterface(请参见 vsCMElement)并表示由该代码类实现的接口。

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

 Sub ImplementedInterfacesExample(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
        ' Retrieve the CodeClass at the insertion point.
        Dim sel As TextSelection = _
            CType(dte.ActiveDocument.Selection, TextSelection)
        Dim cls As CodeClass = _
            CType(sel.ActivePoint.CodeElement( _
            vsCMElement.vsCMElementClass), CodeClass)

        ' Display the class's implemented interfaces.
        Dim ifaces As String
        Dim iface As CodeInterface
        For Each iface In cls.ImplementedInterfaces
            ifaces &= iface.Name & vbCrLf
        Next

        MsgBox(cls.Name & " implements the following interfaces:" & _
            vbCrLf & vbCrLf & ifaces)
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try

End Sub
public void ImplementedInterfacesExample(DTE2 dte)
{
    // Before running this example, open a code document from a project
    // and place the insertion point inside a class definition.
    try
    {
        // Retrieve the CodeClass at the insertion point.
        TextSelection sel = 
            (TextSelection)dte.ActiveDocument.Selection;
        CodeClass cls = 
            (CodeClass)sel.ActivePoint.get_CodeElement(
            vsCMElement.vsCMElementClass);

        // Display the class's implemented interfaces.
        string ifaces = "";
        
        foreach (CodeInterface iface in cls.ImplementedInterfaces)
            ifaces += iface.Name + "\n";

        MessageBox.Show(cls.Name + 
            " implements the following interfaces:\n\n" + ifaces);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}
