FileCodeModel.AddInterface 方法

创建新的接口代码构造,并将代码插入正确的位置。

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

语法

声明
Function AddInterface ( _
    Name As String, _
    Position As Object, _
    Bases As Object, _
    Access As vsCMAccess _
) As CodeInterface
CodeInterface AddInterface(
    string Name,
    Object Position,
    Object Bases,
    vsCMAccess Access
)
CodeInterface^ AddInterface(
    String^ Name, 
    Object^ Position, 
    Object^ Bases, 
    vsCMAccess Access
)
abstract AddInterface : 
        Name:string * 
        Position:Object * 
        Bases:Object * 
        Access:vsCMAccess -> CodeInterface 
function AddInterface(
    Name : String, 
    Position : Object, 
    Bases : Object, 
    Access : vsCMAccess
) : CodeInterface

参数

  • Position
    类型:System.Object
    可选。默认值 = 0。将在其后添加新元素的代码元素。如果该值为 CodeElement,则紧跟在其后添加新元素。
    如果该值为 Long 数据类型,则 AddInterface 指示在哪个元素的后面添加新元素。
    因为集合从 1 开始计数,所以传递 0 指示应将新元素放置在集合的开始处。值为 -1 表示应将元素放在结尾处。
  • Bases
    类型:System.Object
    可选。默认值为 Nothing。一个保存 SafeArray 的变量,该 SafeArray 包含完全限定类型名或新接口派生自的 CodeInterface 对象。

返回值

类型:EnvDTE.CodeInterface
一个 CodeInterface 对象。

备注

Visual C++ 要求其完全限定的类型名使用以冒号分隔 (::) 的格式。 所有其他语言都支持以句点分隔的格式。

参数正确与否由代码模型后面的语言决定。

示例

Sub AddInterfaceExample2(ByVal dte As DTE2)

    ' Before running this example, open a code document from a project.
    Try
        Dim projItem As ProjectItem = dte.ActiveDocument.ProjectItem
        Dim cm As CodeModel = projItem.ContainingProject.CodeModel

        ' Initialize the base interfaces array.
        Dim bases() As Object = { _
            ConvertFullName(cm, "System.IDisposable"), _
            ConvertFullName(cm, "System.IComparable") _
       }

        ' Create a new class.
        projItem.FileCodeModel.AddInterface("TestInterface", , bases)
    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
public void AddInterfaceExample2(DTE2 dte)
{
    // Before running this example, open a code document from 
    // a project.
    try
    {
        ProjectItem projItem = dte.ActiveDocument.ProjectItem;
        CodeModel cm = projItem.ContainingProject.CodeModel;

        // Initialize the base interfaces array.
        object[] bases = {
        ConvertFullName(cm, "System.IDisposable"), 
        ConvertFullName(cm, "System.IComparable")
        };

        // Create a new class.
        projItem.FileCodeModel.AddInterface("TestInterface", -1, bases, 
            vsCMAccess.vsCMAccessPublic);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

string ConvertFullName(CodeModel cm, string fullName)
{
    // Convert a .NET type name into a C++ type name.
    if ((cm.Language == CodeModelLanguageConstants.vsCMLanguageVC) || 
        (cm.Language == CodeModelLanguageConstants.vsCMLanguageMC))
        return fullName.Replace(".", "::");
    else
        return fullName;
}
