Definition

Namespace:

EnvDTE

Assembly:

Microsoft.VisualStudio.Interop.dll

Package:

Microsoft.VisualStudio.Interop v17.12.40391

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

EnvDTE::CodeClass AddClass(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(8)]
public EnvDTE.CodeClass AddClass (string Name, object Position, object Bases, object ImplementedInterfaces, EnvDTE.vsCMAccess Access = EnvDTE.vsCMAccess.vsCMAccessDefault);

[<System.Runtime.InteropServices.DispId(8)>]
abstract member AddClass : string * obj * obj * obj * EnvDTE.vsCMAccess -> EnvDTE.CodeClass

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

Parameters

Name

String

Required. The name of the class.

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 AddClass(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

Optional. Default = 0. A SafeArray of fully qualified type names or CodeClass objects from which the new class inherits its implementations.

ImplementedInterfaces

Object

Optional. Default = 0. A SafeArray of fully qualified type names or CodeInterface objects, each representing an interface that the new class promises to implement.

Access

vsCMAccess

Optional. A vsCMAccess constant.

Returns

CodeClass

A CodeClass object.

Attributes

DispIdAttribute
