本文展示了如何在WPF环境下通过主窗口和子窗口菜单实现多窗口层次感和子窗口的跳转操作，详细介绍了主窗口与子窗口的XAML和代码实现。

比起MFC，WPF下的多窗口实现更有层次感。下面的例子中，在主窗口下点击SubWindow菜单键实现子窗口的跳出。

1：工程右键[add] -->[Window], 本次添加的名称为SubWindow。完成之后，工程目录如下图所示：

2：主窗口代码如下：

MainWindow.xaml代码：

<Window x:Class="WpfMultiWindows.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="394" Width="537" Background="#FF030944">
    <Grid>
        <Menu Margin="0,0,0,335" HorizontalAlignment="Left" Width="529">
            <MenuItem Header="_SubWindow">
                <MenuItem Header="_New SubWindow" Click="Button_Click_SubWindow"/>
            </MenuItem>
        </Menu>
    </Grid>


</Window>

MainWindow.xaml.cs代码：

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 WpfMultiWindows
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        static int SubWindowsNum = 0;
        private void Button_Click_SubWindow(object sender, RoutedEventArgs e)
        {
            SubWindowsNum++;
            SubWindow sw = new SubWindow();
            sw._Value2 = "I'm number " + SubWindowsNum.ToString() + " SubWindow!" ;
            sw.Show();
            return;
        }

    }

}

3：子窗口代码如下：

SubWindow.xaml代码：

<Window x:Class="WpfMultiWindows.SubWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="SubWindowDebug" Height="200.952" Width="269.96" Background="#FF0C7272">
    <Grid Name="Grid1">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="50*"/>
            <ColumnDefinition Width="23*"/>
        </Grid.ColumnDefinitions>
        <TextBox HorizontalAlignment="Left" Height="32" Margin="47,64,0,0" TextWrapping="Wrap" Text="{Binding Path=TextBoxValue}" VerticalAlignment="Top" Width="180" Grid.ColumnSpan="2"/>
    </Grid>
</Window>

SubWindow.xaml.cs代码：

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.Shapes;


using System.ComponentModel;

namespace WpfMultiWindows
{
    /// <summary>
    /// Interaction logic for SubWindowDebug.xaml
    /// </summary>
    public partial class SubWindow : Window, INotifyPropertyChanged
    {
       public int SubWindowNum;

       public event PropertyChangedEventHandler PropertyChanged;

        protected void NotifyPropertyChanged(string property)
        {
            if (PropertyChanged != null)
            {
               PropertyChanged(this, new PropertyChangedEventArgs(property));
            }
        }

        public string _Value2;

        public string TextBoxValue
        {
            get { return _Value2; }
            set
            {
                if (value != _Value2)
                {
                    _Value2 = value;
                    NotifyPropertyChanged("TextBoxValue");
                }
            }
        }


        public SubWindow()
        {
            InitializeComponent();
            Grid1.DataContext = this;
        }

    }
}

运行程序，每点击一次[SubWindow]--->[New SubWindow]之后，都会弹出一个子窗口，并根据顺序编号。
