我已经在SO上找到了关于这个问题的几个信息,但不知怎的,我真的没有得到它;-)从我所看到的,由于安全原因,PasswordBox的密码不能绑定到属性,即保持内存中的普通密码。
我的模型包含:
private SecureString password;
public SecureString Password {
get { return password; }
set { password = value; }
}
虽然不支持绑定到PasswordBox的数据,但Microsoft必须一些想法如何从PasswordBox获取密码并以安全的方式使用它,是吗?
这可能是一种适当且相对简单的方法吗?

因此,我写了一个UserControl
,其中包含一个可绑定的密码 - SecureString
。此UserControl
的代码如下所示:

public partial class BindablePasswordBox : UserControl
{
public static readonly DependencyProperty SecurePasswordProperty = DependencyProperty.Register(
"SecurePassword", typeof(SecureString), typeof(BindablePasswordBox), new PropertyMetadata(default(SecureString)));
public SecureString SecurePassword
{
get { return (SecureString)GetValue(SecurePasswordProperty); }
set { SetValue(SecurePasswordProperty, value); }
}
public BindablePasswordBox()
{
InitializeComponent();
}
private void PasswordBox_OnPasswordChanged(object sender, RoutedEventArgs e)
{
SecurePassword = ((PasswordBox)sender).SecurePassword;
}
private void BindablePasswordBox_OnGotFocus(object sender, RoutedEventArgs e)
{
passwordBox.Focus();
}
}

<PasswordBox Height="29" HorizontalAlignment="Left" Margin="191,136,0,0" Name="textPassword" VerticalAlignment="Top" PasswordChar="*" Width="167" />
密码箱名称为textPassword
:
String pass = textPassword.Password;
