c# 无边框窗体鼠标点击移动两种方法

1.在mouse事件中实现
2.调用windows API

实现方式为：

1.在mouse事件中实现

        Point mouseOff;//鼠标移动位置变量        bool leftFlag;//标签是否为左键        private void groupControl1_MouseUp(object sender, MouseEventArgs e)        {            if (leftFlag)            {                leftFlag = false;//释放鼠标后标注为false;            }        }        private void groupControl1_MouseMove(object sender, MouseEventArgs e)        {            if (leftFlag)            {                Point mouseSet = Control.MousePosition;                mouseSet.Offset(mouseOff.X, mouseOff.Y);  //设置移动后的位置                Location = mouseSet;            }        }        private void groupControl1_MouseDown(object sender, MouseEventArgs e)        {                        if (e.Button == MouseButtons.Left)            {                mouseOff = new Point(-e.X, -e.Y); //得到变量的值                leftFlag = true;                  //点击左键按下时标注为true;            }        }        private void groupControl1_MouseDown(object sender, MouseEventArgs e)        {                      if (e.Button == MouseButtons.Left)            {                mouseOff = new Point(-e.X, -e.Y); //得到变量的值                leftFlag = true;                  //点击左键按下时标注为true;            }        }

2.调用windows API

调用前需要添加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);        private void groupControl1_MouseDown(object sender, MouseEventArgs e)        {            if (e.Button == MouseButtons.Left)            {                ReleaseCapture(); //释放鼠标捕捉                //发送左键点击的消息至该窗体(标题栏)                SendMessage(Handle, 0xA1, 0x02, 0);            }                  }
