点击winform窗体进行移动

先说下改变窗体样式的代码，如下：

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

 

实现点击winform窗体,运用鼠标就可以移动窗体，而不需要点击窗体边框处。

using System.Runtime.InteropServices;

在窗体内加上以下代码：

[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 Longin_MouseDown(object sender, MouseEventArgs e)
        {
            ReleaseCapture();
            SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
        }
