You have to use PasswordBoxinstead of TextBox:
你必须使用PasswordBox而不是TextBox：
<PasswordBox Height="42" Width="200" Margin="22,28,28,0"
Name="passwordBox1" VerticalAlignment="Top"
Background="LightBlue" Foreground="DarkBlue"
MaxLength="25" PasswordChar="*"
/>

There's a new control in WPF designed for passwords, it's called PasswordBox. You should use that instead of a TextBoxif you need to mask the input.
WPF 中有一个专为密码设计的新控件，称为PasswordBox. TextBox如果您需要屏蔽输入，您应该使用它而不是 a 。
Here's a brief article about it.To retrieve the value that was entered, use the Passwordproperty.
这是一篇关于它的简短文章。要检索输入的值，请使用Password属性。
EDIT: You've pretty much asked a new question - how can you unmask the text in a WPF PasswordBox? To the best of my knowledge you can't, though you could of course display it in a regular TextBox on demand by getting the value of the password from PasswordBox.Password
编辑：您几乎问了一个新问题 -如何在 WPF PasswordBox 中取消屏蔽文本？据我所知，您不能，尽管您当然可以通过从PasswordBox.Password
Databinding to a PasswordBoxisn't possible without a custom helper class - though this would reduce the increased security offered by the new PasswordBoxcontrol (as described here). With that considered, this article includes a section on creating a helper classthat allows you to databind to a PasswordBox.
PasswordBox如果没有自定义帮助程序类，数据绑定到 a是不可能的 - 尽管这会降低新PasswordBox控件提供的增加的安全性（如此处所述）。考虑到这一点，本文包含一个关于创建帮助类的部分，该类允许您将数据绑定到PasswordBox.

Or use 'password font'. A font that shows all characters as dots. Remember to disable cut and copy clipboard functions.
或使用“密码字体”。一种将所有字符显示为点的字体。请记住禁用剪切和复制剪贴板功能。

There are also custom implementations of PasswordBoxwhich you can alter for your needs, see
this article. You also can extend this which is not possible with the PasswordBoxbecause its a sealed class.
PasswordBox您还可以根据需要更改自定义实现，请参阅
本文。您也可以扩展它，这是不可能的，PasswordBox因为它是一个密封类。
