在密码盒中显示密码的好方法

Question

我想知道是否有人有任何好主意如何显示密码在密码盒。我知道你可以将文本框绑定到密码盒，但这不是另一种方法吗?

Answer 1

如果你想让你的密码可见，你应该使用一个文本框。密码框的唯一功能是屏蔽输入。它不提供额外的功能。也可以在运行时切换文本框和密码框

Answer 2

在PasswordBox控件中没有任何内置属性来显示密码字符。但是我们可以通过TextBox控件在PasswordBox中显示密码。用于WPF中具有显示/隐藏功能的密码框。我们将使用两个TextBlock控件，TextBox控件，PasswordBox控件，Image控件

string AppPath = Directory.GetCurrentDirectory();
public MainWindow()
{
    InitializeComponent();
    ImgShowHide.Source = new BitmapImage(new Uri(AppPath + "\img\clip.jpg"));
}
private void ImgShowHide_PreviewMouseUp(object sender, MouseButtonEventArgs e)
{
    HidePassword();
}
private void ImgShowHide_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    ShowPassword();
}
private void ImgShowHide_MouseLeave(object sender, MouseEventArgs e)
{
    HidePassword();
}
private void txtPasswordbox_PasswordChanged(object sender, RoutedEventArgs e)
{
    if(txtPasswordbox.Password.Length > 0)
        ImgShowHide.Visibility = Visibility.Visible;
    else
        ImgShowHide.Visibility = Visibility.Hidden;
}
void ShowPassword()
{
    ImgShowHide.Source = new BitmapImage(new Uri(AppPath + "\img\cus.jpg"));
    txtVisiblePasswordbox.Visibility = Visibility.Visible;
    txtPasswordbox.Visibility = Visibility.Hidden;
    txtVisiblePasswordbox.Text = txtPasswordbox.Password;
}
void HidePassword()
{
    ImgShowHide.Source = new BitmapImage(new Uri(AppPath + "\img\clip.jpg"));
    txtVisiblePasswordbox.Visibility = Visibility.Hidden;
    txtPasswordbox.Visibility = Visibility.Visible;
    txtPasswordbox.Focus();
}

这里有一个好而简单的方法，你可以从这里下载密码字体并在文本框中使用它作为字体，而不是passwordbox当你想显示密码时，你所要做的就是把字体从"Password"到"Microsoft Sans Serif"或者任何东西//例如，当我点击复选框:

Private Sub ChkShowPass_Click(sender As Object, e As RoutedEventArgs)
    If ChkShowPass.IsChecked = True Then
        'show Password
        TxtPassword.FontFamily = New FontFamily("Microsoft Sans Serif")
    ElseIf ChkShowPass.IsChecked = False Then
        'hide Password
        TxtPassword.FontFamily = New FontFamily("Password")
    End If
End Sub
