FileCodeModel2.AddStruct 方法 (String, Object, Object, Object, vsCMAccess)

2008-09-04

更新：2007 年 11 月

创建新的结构代码构造，并将代码插入正确的位置。

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

语法

声明
Function AddStruct ( _
    Name As String, _
    Position As Object, _
    Bases As Object, _
    ImplementedInterfaces As Object, _
    Access As vsCMAccess _
) As CodeStruct
用法
Dim instance As FileCodeModel2
Dim Name As String
Dim Position As Object
Dim Bases As Object
Dim ImplementedInterfaces As Object
Dim Access As vsCMAccess
Dim returnValue As CodeStruct

returnValue = instance.AddStruct(Name, _
    Position, Bases, ImplementedInterfaces, _
    Access)

CodeStruct AddStruct(
    string Name,
    Object Position,
    Object Bases,
    Object ImplementedInterfaces,
    vsCMAccess Access
)

CodeStruct^ AddStruct(
    String^ Name, 
    Object^ Position, 
    Object^ Bases, 
    Object^ ImplementedInterfaces, 
    vsCMAccess Access
)

function AddStruct(
    Name : String, 
    Position : Object, 
    Bases : Object, 
    ImplementedInterfaces : Object, 
    Access : vsCMAccess
) : CodeStruct

参数

Name
类型：System.String

必选。新结构的名称。

Position
类型：System.Object

可选。默认为 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 AddStruct 指示在哪个元素后添加新元素。

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

必选。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。

ImplementedInterfaces
类型：System.Object

必选。默认值为 Nothing。一个包含完全限定类型名或 CodeInterface 对象（每个对象都表示新类承诺实现的接口）的 SafeArray。

Access
类型：EnvDTE.vsCMAccess

可选。一个 vsCMAccess 常数。

返回值

类型：EnvDTE.CodeStruct

CodeStruct 对象。

实现

FileCodeModel.AddStruct(String, Object, Object, Object, vsCMAccess)

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 AddStructExample2(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 classes array and the implemented 
        ' interfaces array.
        Dim bases() As Object = {ConvertFullName(cm, "System.Object")}
        Dim interfaces() As Object = { _
            ConvertFullName(cm, "System.IDisposable"), _
            ConvertFullName(cm, "System.IComparable") _
        }

        ' Create a new struct.
        projItem.FileCodeModel.AddStruct("TestStruct", , bases, _
            interfaces)
    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
