vs2005 鼠标点击事件移动

导入: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;
定义一个方法:
public static void MoveForm(IntPtr hwnd)
{
ReleaseCapture();
SendMessage(hwnd, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
}

放在窗体的鼠标点击事件即可
private void Form_MouseDown(object sender, MouseEventArgs e)
{
MoveForm(this.Handle);
}
