移动没有标题的窗体?

[gggitxai]

请问怎样才能移动没有标题的窗体?列如在VB中可以调用API来完成,请问C#中怎样实现?

可以在mouse_down事件中发送WM_NCLBUTTONDOWN来实现你要的效果,可以参考下面的代码.

using System.Runtime.InteropServices;
............
public const int WM_NCLBUTTONDOWN = 0xA1;
public const int HTCAPTION = 0x2;

[DllImportAttribute ("user32.dll")]
public static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);

[DllImportAttribute ("user32.dll")]
public static extern bool ReleaseCapture();

private void Form2_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
ReleaseCapture();
SendMessage(Handle, WM_NCLBUTTONDOWN, HTCAPTION, 0);
}

protected override void WndProc(ref Message msg)
{

base.WndProc(ref msg);
if (msg.Msg == 0x0084)
{
if(msg.Result == new IntPtr(1))
{
msg.Result = new IntPtr(2);
return;
}

}


}

我以前用vb的时候曾经是直接通过鼠标的位置来判断移动的，效果很自然，我想你可以考虑。
