Definition

Namespace:

Assembly:

Package:

Microsoft.VisualStudio.Interop v17.12.40391

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

EnvDTE::CodeStruct AddStruct(std::wstring const & Name, winrt::Windows::Foundation::IInspectable const & Position, winrt::Windows::Foundation::IInspectable const & Bases, winrt::Windows::Foundation::IInspectable const & ImplementedInterfaces, EnvDTE::vsCMAccess Access = EnvDTE.vsCMAccess.vsCMAccessDefault);

public EnvDTE.CodeStruct AddStruct (string Name, object Position, object Bases, object ImplementedInterfaces, EnvDTE.vsCMAccess Access = EnvDTE.vsCMAccess.vsCMAccessDefault);

[<System.Runtime.InteropServices.DispId(13)>]
abstract member AddStruct : string * obj * obj * obj * EnvDTE.vsCMAccess -> EnvDTE.CodeStruct

Public Function AddStruct (Name As String, Optional Position As Object, Optional Bases As Object, Optional ImplementedInterfaces As Object, Optional Access As vsCMAccess = EnvDTE.vsCMAccess.vsCMAccessDefault) As CodeStruct

Parameters

Name

String

Required. The name of the new structure.

Position

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(String, Object, Object, Object, vsCMAccess) 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

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

Object

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

Access

vsCMAccess

Optional. A vsCMAccess constant.

Returns

CodeStruct

A CodeStruct object.

Attributes

DispIdAttribute

Remarks

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.
