CodeClass2.AddStruct Method

Creates a new structure in the class.

Namespace:  EnvDTE80

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

Parameters

• Name
  Type: System.String
  Required. The name of the new structure.

• Position
  Type: System.Object
  Optional. Default = 0. The code element after which to add the new element.
  If the value is a Long data type, then the Position method indicates the element after which to add the new element.
  Because collections begin their count at 1, passing 0 indicates that the new element should be placed at the beginning of the collection. A value of -1 means the element should be placed at the end.

• Bases
  Type: System.Object
  Required. Default value is Nothing. A variant that holds a SafeArray of fully qualified type names or CodeInterface objects from which the new struct derives.

• ImplementedInterfaces
  Type: System.Object
  Required. Default value is Nothing. A SafeArray of fully qualified type names or CodeInterface objects representing interfaces that the new class promises to implement.

• Access
  Type: EnvDTE.vsCMAccess
  Optional. A vsCMAccess constant.

Return Value

Type: EnvDTE.CodeStruct
A CodeStruct object.

Implements

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

Remarks

Native Visual C++ requires the colon-separated (::) format for its fully qualified type names. All other languages support the period-separated format.

The correctness of the arguments is determined by the language behind the code model.

Note

The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).

Examples

[Visual Basic]

Sub AddStructExample(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.
        cm.AddStruct("TestStruct", projItem.Name, , 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
