[<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
