按引用调用线程 （.Net）

问：

以下不起作用，因为 Is not an 因为它接收了它的参数。这意味着以下追加以调用具有值的线程的代码不起作用。Sub(ByRef t As T) ...Action(Of T)ByRefByRef

Public Sub UseLater(Of T As Structure)(ByRef t As T, m As Mutex, callback As [Delegate]) 'Includes ByRef Consumer
  m.WaitOne()
  m.ReleaseMutex()
  callback(t)
End Sub

''...

  Dim getterLock As New Mutex()
  Dim buffer As MyType = Nothing
  Dim threadhelper As [Delegate] = Sub(ByRef t As MyType) ''ISSUE: Action arg cannot be ByRef
                                     UseLater(Of MyType)(t, getterLock, Sub(ByRef t_ As MyType) buffer = t_)
                                   End Sub

  getterLock.WaitOne()
  Dim getLater As New Thread(threadhelper)
  getLater.Start(MyObject) ''Currently in scope object
  Dim getter As [Delegate] = Function() As MyType
                               getterLock.ReleaseMutex()
                               Return buffer
                             End Function

''getter can be passed out of scope

如何调用带有 ？ （或者等价地从 getter 和 setter 那里获得？ByRefFunc(Of T)Action(Of T)ByRef
