Bind a WPF passwordbox
提问by NoIdea123
I want to bind a Passwordbox in the XAML code. Now I found out that it isn′t possible to bind it because you haven′t any dependency property.
我想在 XAML 代码中绑定一个密码框。现在我发现不可能绑定它，因为你没有任何依赖属性。
For my case I don′t need any security in my Application. I just don′t want to display clear text to the user. Is there any other option to realize a kind of passwordbox with a textbox or so on?
就我而言，我的应用程序不需要任何安全性。我只是不想向用户显示明文。有没有其他选择来实现一种带有文本框等的密码框？

The Passwordproperty is not a dependency property -- for security reasons. You can easily get the plain-text password, though.
Password出于安全原因，该属性不是依赖属性。不过，您可以轻松获得纯文本密码。
XAML:
XAML：
<PasswordBox
x:Name="passwordBox"
PasswordChanged="OnPasswordChanged" />
Code-behind event handler:
代码隐藏事件处理程序：
private void OnPasswordChanged(
object sender,
RoutedEventArgs e)
{
Debug.WriteLine(passwordBox.Password);
}
