c# winform使用 wpf控件

 public partial class CustomBtnControl : UserControl
    {
        public CustomBtnControl()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("YOU CLICK");
        }
    }
}

阴影效果是没法用winform做的，
