  • Article

Creates a new structure code construct and inserts the code in the correct location.

Namespace:  EnvDTE
Assembly:  EnvDTE (in EnvDTE.dll)

Syntax

'Declaration
Function AddStruct ( _
    Name As String, _
    Location As Object, _
    Position As Object, _
    Bases As Object, _
    ImplementedInterfaces As Object, _
    Access As vsCMAccess _
) As CodeStruct

function AddStruct(
    Name : String,

) : CodeStruct

Parameters

  • Name
    Type: System.String

    Required. The name of the new structure.

  • Location
    Type: System.Object

    Required. The path and file name for the new structure definition. Depending on the language, the file name is either relative or absolute to the project file. The file is added to the project if it is not already a project item. If the file cannot be created and added to the project, then AddStruct fails.

  • Position
    Type: System.Object

    Optional. Default = 0. The code element after which to add the new element. If the value is a CodeElement, then the new element is added immediately after it.

    If the value is a Long data type, then AddStruct 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 that 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 interface derives.

  • ImplementedInterfaces
    Type: System.Object

    Required. Default value is Nothing. A SafeArray of fully qualified type names orCodeInterface objects representing interfaces that the new class promises to implement.

Return Value

Type: EnvDTE.CodeStruct
A CodeStruct object.

Remarks

Native 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

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.
