优化以下代码 Function Startup(ByVal args As String()) As Integer theUI.MenuBarManager.AddMenuAction("my_app_hello", AddressOf HelloCB) theUI.MenuBarManager.AddMenuAction("my_app_goodbye", AddressOf GoodbyeCB) theUI.MenuBarManager.AddMenuAction("AXTOOLS_fastdrill", AddressOf fastdrill) theUI.MenuBarManager.AddMenuAction("SAMPLE_VB_APP__action1", AddressOf PrintButtonIdCB) theUI.MenuBarManager.AddMenuAction("SAMPLE_VB_APP__action2", AddressOf TestCallbackReturnsCB) theUI.MenuBarManager.AddMenuAction("SAMPLE_VB_APP__action3", AddressOf PrintApplicationIdCB) theUI.MenuBarManager.AddMenuAction("SAMPLE_VB_APP__action4", AddressOf PrintButtonDataCB) theUI.MenuBarManager.AddMenuAction("SAMPLE_VB_APP__action5", AddressOf PrintToggleStatusCB) theUI.MenuBarManager.AddMenuAction("AXTOOLS_fastdrill", AddressOf fastdrill) Return 0 End Function

这段代码看起来已经很简洁了，不过我们可以尝试进行一些优化。一个可能的优化是将重复的代码合并，避免重复调用`AddMenuAction`方法。

Function Startup(ByVal args As String()) As Integer
    Dim menuBarManager = theUI.MenuBarManager

    menuBarManager.AddMenuAction("my_app_hello", AddressOf HelloCB)
    menuBarManager.AddMenuAction("my_app_goodbye", AddressOf GoodbyeCB)
    menuBarManager.AddMenuAction("AXTOOLS_fastdrill", AddressOf fastdrill)
    menuBarManager.AddMenuAction("SAMPLE_VB_APP__action1", AddressOf PrintButtonIdCB)
    menuBarManager.AddMenuAction("SAMPLE_VB_APP__action2", AddressOf TestCallbackReturnsCB)
    menuBarManager.AddMenuAction("SAMPLE_VB_APP__action3", AddressOf PrintApplicationIdCB)
    menuBarManager.AddMenuAction("SAMPLE_VB_APP__action4", AddressOf PrintButtonDataCB)
    menuBarManager.AddMenuAction("SAMPLE_VB_APP__action5", AddressOf PrintToggleStatusCB)

    Return 0
End Function

在这个优化后的代码中，我们创建了一个`menuBarManager`变量并将其赋值为`theUI.MenuBarManager`。然后，我们使用这个变量来连续调用`AddMenuAction`方法，避免多次重复访问`theUI.MenuBarManager`对象。

注意，这种优化并不会改变代码的功能，只是让代码更易读和简洁一些。
