4种方法实现C#无标题栏窗体的移动

首先C#无标题栏窗体的实现代码

在load时实现

无工具栏+无窗口标题

         private void Form1_Load(object sender, EventArgs e)
         {
             this.ControlBox = false;
             this.Text = "";
         }

这样就可以实现无标题栏窗体了,示例效果

第一种实现点击窗口内区域移动窗体的方法

重写wndproc，截取在窗体区域内移动的消息，

         protected override void WndProc(ref Message m)
         {
             base.WndProc(ref m);
                 )
                 {
                         m.Result = );

                 }

         }

第二种实现方法

private void Form1_Load(object sender, EventArgs e)
        {
            this.MouseMove+=Form1_MouseMove;
        }

        [DllImport("user32.dll", EntryPoint = "SendMessage")]
        public static extern int SendMessage(IntPtr hWnd, int wMsg, int wParam, int lParam);
        [DllImport("user32.dll", EntryPoint = "ReleaseCapture")]
        public static extern int ReleaseCapture();  

        private void Form1_MouseMove(object sender, MouseEventArgs e)
        {
            ReleaseCapture();//使鼠标事件对当前窗体持续有效
            SendMessage();
        }

第三种

截取鼠标在窗体内按下左键时的消息,改为鼠标在标题栏下按下左击的事件实现移动

         protected override void WndProc(ref Message m)
         {
             if(m.Msg==0x201)
             {
                 m.Msg = 0xA1;
                 m.WParam = );
             }
             base.WndProc(ref m);
         }

第四种最原始的方法

mousedown事件是改变一个bool变量

mousemove时先判断bool变量，移动时设置窗体的location

mouseup时改变bool变量

         bool mouse_down = false;//鼠标左键是否被按下
         Point mouse_start_point;//记录按下左键时的鼠标位置
         Point form_start_point;//记录按下左键时窗口位置

         private void Form1_Load(object sender, EventArgs e)
         {
             this.ControlBox = false;
             this.Text = "";

             this.MouseMove+=Form1_MouseMove;
             this.MouseUp+=Form1_MouseUp;
             this.MouseDown+=Form1_MouseDown;
         }

         private void Form1_MouseDown(object sender, MouseEventArgs e)
         {
             if (e.Button == MouseButtons.Left)
             {
                 this.mouse_down = true;
                 this.mouse_start_point = Control.MousePosition;
                 this.form_start_point = this.Location;
             }
         }

         private void Form1_MouseUp(object sender, MouseEventArgs e)
         {
             this.mouse_down = false;
         }

         private void Form1_MouseMove(object sender, MouseEventArgs e)
         {
             if(this.mouse_down==true)
             {
                 this.Location = new Point(this.form_start_point.X + PointToScreen(e.Location).X - this.mouse_start_point.X, this.form_start_point.Y + PointToScreen(e.Location).Y - this.mouse_start_point.Y);
             }
         }

     }
