密码输入框需要输入的密码不能显示明文，用其他的特殊字符代替显示。
显示效果如下：
这里写图片描述

Xaml部分代码如下：

<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>

后台代码如下：

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 的交互逻辑    /// </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)                      }                }            });        }    }}
