VBA 变量去重

If InStr(Receiver, new_receiver) Then

                Else

                    Receiver = Receiver + new_receiver  + ";"        ' add Receiver******

                End If

 InStr(Receiver, new_receiver) 得到Booleans 值 ture or false, 从而知道new_receiver 是否已经存在Receiver 中，进而决定是否往其中添加new_receiver，保持Receiver 中变量唯一，从而得到去重的目的。
