我不知道COSMOS是什么。下一次，提供你正在谈论的内容的链接，这样每个人都在同一页面上。



记住，我们看不到你的显示器，内容你的硬盘，或读你的想法。





但是，有一个TextBox的PasswordChar属性。你所要做的就是将它设置为你想要的角色，你输入的任何东西都被那个角色所取代。

I have no idea what COSMOS is. Next time, provide a link to what you're talking about so everyone is on the same page.

Remember, we can't see your monitor, the contents of your hard drive, or read your mind.


But, there's a PasswordChar property of a TextBox. All you have to do is set that to the character you want and anything you type is replaced by that character.
