public partial class Form1 : Form
    {
        private const int SW_HIDE = 0;
        private const int SW_NORMAL = 1;
        private const int SW_MAXIMIZE = 3;
        private const int SW_SHOWNOACTIVATE = 4;
        private const int SW_SHOW = 5;
        private const int SW_MINIMIZE = 6;
        private const int SW_RESTORE = 9;
        private const int SW_SHOWDEFAULT = 10;

        [System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint = "ShowWindow", SetLastError = true)]
        static extern bool ShowWindow(IntPtr hWnd, uint nCmdShow);

        /// <summary>
        /// 根据窗口标题查找窗体

        /// <returns></returns>
        [System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint = "FindWindow")]
        private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            IntPtr hWnd = FindWindow(null, "无标题 - 记事本");
