我在 VBA 中有这段代码(以简化版本显示):

Sub TheMenu()
    Dim Obj As CommandBar
    Set Obj = Application.CommandBars.Add(Position:=msoBarPopup, MenuBar:=False, Temporary:=True)
    Obj.Controls.Add(Type:=msoControlButton).Caption = "Button1"
    Obj.Controls.Add(Type:=msoControlButton).Caption = "Button2"
    Obj.ShowPopup
End Sub

我希望在 VB.NET 中做一些等价的东西(意思是“看起来相似并且用途相似”，我不需要更多)。你知道有什么方法吗？


我在 VS2015 中使用，一个使用 .NET framework 4.6.1 的“Windows 窗体应用程序”项目。

您可以在此处按照以下示例进行操作:

   Private Const MY_COMMAND_NAME As String = "MyCommand"

   Private applicationObject As EnvDTE.DTE

   Private myTemporaryCommandBarPopup As CommandBarPopup
