WPF 使用TextBox做密碼輸入框
阿新 • • 發佈:2018-11-10
密碼輸入框需要輸入的密碼不能顯示明文,用其他的特殊字元代替顯示。
顯示效果如下:
Xaml部分程式碼如下:
<Window x:Class="TextBoxPwd.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:TextBoxPwd"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<StackPanel>
<TextBox FontFamily="Courier New" x:Name="pwd" FontSize="20" Foreground="Transparent" Text="sdfsddfsfs"/>
<TextBox FontFamily ="Courier New" FontSize="20" Text="sdfsddfsfs"/>
</StackPanel>
</Window>
後臺程式碼如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace TextBoxPwd
{
/// <summary>
/// MainWindow.xaml 的互動邏輯
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
pwd.TextDecorations = new TextDecorationCollection(new TextDecoration[] {
new TextDecoration() {
Location= TextDecorationLocation.Strikethrough,
Pen= new Pen(Brushes.Black, 10f) {
DashCap = PenLineCap.Round,
StartLineCap= PenLineCap.Round,
EndLineCap= PenLineCap.Round,
DashStyle= new DashStyle(new double[] {0.0,1.2 }, 0.6f)
}
}
});
}
}
}
