最简单的移动无边框窗体的方法

网上搜了一下，发现方法很多，有些也不太好用，代码也长，经测试总结出以下代码

 

 using System.Runtime.InteropServices;
 
        [DllImport("user32.dll")]
        public static extern bool ReleaseCapture();
        [DllImport("user32.dll")]
        public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
        public const int WM_SYSCOMMAND = 0x0112;
        public const int SC_MOVE = 0xF010;
        public const int HTCAPTION = 0x0002;
  
        private void toolStrip1_MouseDown(object sender, MouseEventArgs e)
        {
            ReleaseCapture();
            SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
        }

 

注：toolStrip1_MouseDown为 点住该控件能使窗体移动的鼠标点击事件
