# WPF 透明自定义窗口
重写了标题栏，最大化、还原、最小化功能。
突然发现忘记加上程序的标题了，算了，懒得添加了。
MainWindow.xaml代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Runtime.InteropServices;
namespace WpfApplication1
{
