Creates a new structure in the class.

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);

[System.Runtime.InteropServices.DispId(68)]
public EnvDTE.CodeStruct AddStruct (string Name, object Position, object Bases, object ImplementedInterfaces, EnvDTE.vsCMAccess Access = EnvDTE.vsCMAccess.vsCMAccessDefault);

[<System.Runtime.InteropServices.DispId(68)>]
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 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: 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: 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: vsCMAccess

Optional. A vsCMAccess constant.

Returns

CodeStruct

A CodeStruct object.

Implements

AddStruct(String, Object, Object, Object, vsCMAccess)

Attributes: DispIdAttribute

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).
