推荐答案

您可以调用的 启用 的形式方法，将其带到前方，如果它是不是已经。

You can call the Activate method on the form to bring it to the front if it isn't already.

不过，请注意，如果不同的程序被激活时，它通常会简单地闪烁桌面按钮（取决于你来自哪里调用它）。这是Windows的标准的保护，防止重点窃取并你不应该去解决它。

However, note that if a different program is active, it will usually simply flash the desktop button (depending where you call it from). This is Windows' standard protection against focus-stealing and you should not try to work around it.
