WPF Window异形窗口演示

我们先通过简单的效果展示，切换展示不同图片：

我们先定义图片资源文件，我们可以在window资源中定义，下面的在app.xaml文件来定义：

<Application x:Class="WPF异形窗口演示.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ImageBrush  ImageSource="1.jpg"  x:Key="key1"></ImageBrush>
        <ImageBrush  ImageSource="2.jpg"  x:Key="key2"></ImageBrush>
    </Application.Resources>
</Application>

然后通过Combox控件来进行资源样式切换

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
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 WPF异形窗口演示
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.comboBox1.Items.Add("样式1");
            this.comboBox1.Items.Add("样式2");
            this.comboBox1.Items.Add("样式3");
            this.comboBox1.SelectedIndex = ;
        }
        private void Grid_MouseMove(object sender, MouseEventArgs e)
        {
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                this.DragMove();

                //   this.Margin = new Thickness(10,10,10,10);
            }
        }

        private void comboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if (this.comboBox1.SelectedValue.ToString() == "样式1")
            {
                //通过uri指向图片位置
                this.Background = new ImageBrush(new System.Windows.Media.Imaging.BitmapImage(new Uri("3.jpg", UriKind.Relative))); ;
            }
            else if (this.comboBox1.SelectedValue.ToString() == "样式2")
            {
                //通过资源文件获取
                this.Background = (ImageBrush)Application.Current.Resources["key1"];

            }
            else if (this.comboBox1.SelectedValue.ToString() == "样式3")
            {
                this.Background = (ImageBrush)Application.Current.Resources["key2"];

            }
        }
    }
}

我们可以通过这样的方式来动态实现不同效果展示
