WPF制作QQ列表（仿qq列表特效）

先看效果图：这个是折叠特效。

 

代码结构：

     model是我们的数据模型，定义了在列表显示的人物名称   图片   简介    。

Resource是我们的图片资源  和 存储图片资源路径、名称的资源文件。

GroupListCreate是我们的主要创建列表的模块。

代码如下：

public StackPanel CreateModuleEntry(List<GroupPerson> hrvGroups)
        {
            if (hrvGroups != null)
            {

                StackPanel spl = new StackPanel();   //创建一个最外围的框
                List<GroupPerson> groups = hrvGroups;
                foreach (GroupPerson g in groups)      //根据分组去遍历
                {
                    int count = 1;
                    Expander ex = new Expander();     //每一个分组
                    ex.Header = g.Name;
                    List<Person> modules = new List<Person>();
                    modules = g.Persons;
                    StackPanel sp = new StackPanel();     //每一个分组的框
                    foreach (Person m in modules)
                    {
                        DockPanel dp = new DockPanel();
                        if (count >= 2)
                        {
                            Thickness dpMargin = new Thickness(0, 10, 0, 0);
                            dp.Margin = dpMargin;
                        }
                        dp.MouseLeave += new System.Windows.Input.MouseEventHandler(dp_MouseLeave);
                        dp.MouseEnter += new System.Windows.Input.MouseEventHandler(dp_MouseEnter);
                        dp.MouseLeftButtonDown += new System.Windows.Input.MouseButtonEventHandler(dp_MouseLeftButtonDown);
                        dp.MouseLeftButtonUp += new System.Windows.Input.MouseButtonEventHandler(dp_MouseLeftButtonUp);
                        //人物头像
                        Bitmap bm = new Bitmap(ImagePathResource.ImageSource+m.Ico);
                        MemoryStream ms = new MemoryStream();
                        bm.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
                        BitmapImage bi = new BitmapImage();
                        bi.BeginInit();
                        bi.StreamSource = new MemoryStream(ms.ToArray());
                        bi.EndInit();
                        ms.Dispose();

                        image.Source = bi;
                        image.Width = 50;
                        image.Height = 50;
                        image.Stretch = Stretch.Fill;


                        //人物名称

                        //说明文字的自动换行
                        for (int i = 0; i < m.Introduction.Length; i++)
                        {
                            string s = m.Introduction.Substring(i, 1);
                            Label lblResume = new Label();
                            lblResume.Content = s;
                            dpl.Children.Add(lblResume);
