CodeClass.RemoveInterface 方法

2011-08-12

从实现的接口列表中移除一个接口。

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

语法

声明
Sub RemoveInterface ( _
    Element As Object _
)

void RemoveInterface(
    Object Element
)

void RemoveInterface(
    Object^ Element
)

abstract RemoveInterface : 
        Element:Object -> unit

function RemoveInterface(
    Element : Object
)

参数

Element
类型：System.Object
必选。一个 CodeElement，或它在集合中的名称。

备注

从 ImplementedInterfaces 集合中移除代码元素。该元素可以是集合中的 CodeElement 对象，或者是集合中某唯一元素的名称。

提示

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 RemoveInterfaceExample(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)

        If MsgBox("Remove all interfaces from " & cls.Name & "?", _
            MsgBoxStyle.YesNo) = MsgBoxResult.Yes Then
            Dim intrface As CodeElement
            For Each intrface In cls.ImplementedInterfaces
                cls.RemoveInterface(intrface)
            Next
        End If
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try

End Sub

Function ConvertFullName(ByVal cm As CodeModel, _
    ByVal fullName As String) As String

    ' Convert a .NET type name into a C++ type name.
    If (cm.Language = CodeModelLanguageConstants.vsCMLanguageVC) Or _
        (cm.Language = CodeModelLanguageConstants.vsCMLanguageMC) Then
        Return fullName.Replace(".", "::")
    Else
        Return fullName
    End If

End Function
