因为界面的要求,要使用一个没有边框的Form,但是这样就没有办法拖动窗口了. 着急等待中...

如何解决拖动的问题?

写窗体的鼠标事件

[TheAres]

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);
}

全局變量 int ox; int oy;

Form_MouseDown(...)
{
ox = e.X;
oy = e.Y;
}

Form_MouseMove(...)
{
if(e.Button == MouseButtons.Left)
{
this.Left += (e.X - ox);
this.Top += (e.Y - oy);
}
}

重载消息处理函数
当程序受到(WM_NCHITTEST)的时候，改变消息的处理结果返回给系统
就是欺骗windows让他以为鼠标点到了表题栏上，这行就可以托动了
protected override void WndProc(ref Message msg)
{
if (msg.Msg == 0x0084) // WM_NCHITTEST
msg.Result = (IntPtr) 2; // HTCAPTION
else
base.WndProc(ref msg);
}
当拖动的时候,转换消息
if (msg.Msg == 0x0084) // WM_NCHITTEST
msg.Result = (IntPtr) 2; // HTCAPTION
else
