取代退货 [英] Replace returning Nothing

问题描述

嗨

我下面有代码；

Msg = ""
Msg = Replace(Msg, "'", "''")

在第二行之后，Msg为Nothing，而我希望它为".这是怎么回事，我该如何避免呢?

After the second line Msg is Nothing while I expected it to be "". What is going on here and how can I avoid Nothing?

谢谢

推荐答案

您将Msg ="设置为这意味着Msg = Nothing

You set Msg="" which means Msg = Nothing

除非消息包含某些内容，否则什么都不会...

Unless Msg contains something it will be nothing...
