    </Grid>
</Window>

2、C#代码

using System;
using System.Windows;
using System.Windows.Media;
using System.Windows.Forms;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
using System.Windows.Controls;

namespace WpfApp
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Pic_BackGround_Click(object sender, RoutedEventArgs e)
        {
            OpenFileDialog pic = new OpenFileDialog();
            pic.Title = "设置背景图片";
            pic.Filter = "图形文件(*.jpg)|*.jpg";
            if (pic.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                ImageBrush p = new ImageBrush(new BitmapImage(new Uri(pic.FileName, UriKind.Absolute)));
                Console.WriteLine(pic.FileName);
                myDockPanel.Background = p;
            }
        }
    }
}

3、演示
a.文件菜单

b.编辑菜单

c.设置背景图片快捷键“Ctrl+Shift+O”
暂且只设置了一个快捷键喔，其它的快捷键，有兴趣的可以类推一下，就出来了(^▽)
