FileCodeModel.AddStruct 方法

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:  EnvDTE
程序集:  EnvDTE(在 EnvDTE.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
CodeStruct AddStruct(
    string Name,
    Object Position,
    Object Bases,
    Object ImplementedInterfaces,
    vsCMAccess Access
)
CodeStruct^ AddStruct(
    String^ Name, 
    Object^ Position, 
    Object^ Bases, 
    Object^ ImplementedInterfaces, 
    vsCMAccess Access
)
abstract AddStruct : 
        Name:string * 
        Position:Object * 
        Bases:Object * 
        ImplementedInterfaces:Object * 
        Access:vsCMAccess -> CodeStruct 
function AddStruct(
    Name : String, 
    Position : Object, 
    Bases : Object, 
    ImplementedInterfaces : Object, 
    Access : vsCMAccess
) : CodeStruct

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 AddStruct 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
    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。

返回值

类型:EnvDTE.CodeStruct
一个 CodeStruct 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 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

End Function

    // a project.

        // interfaces array.

        object[] interfaces = {
            ConvertFullName(cm, "System.IDisposable"),
            ConvertFullName(cm, "System.IComparable")
        };

        // Create a new struct.
        projItem.FileCodeModel.AddStruct("TestStruct", -1, bases, 
            interfaces, 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;
}
