隐藏标题栏(窗口属性)：
1、设置在该窗体的标题栏中是否显示控件框：
this.ControlBox = false;
2、设置在该窗体的标题为空：
this.Text = string.Empty;
3、移动窗口：实现Form的函数WndProc
#region 实现点击移动
internal static int WM_NCHITTEST = 0x84;
internal static IntPtr HTCLIENT = (IntPtr)0x1;
internal static IntPtr HTCAPTION = (IntPtr)0x2;
internal static int WM_NCLBUTTONDBLCLK = 0x00A3;
protected override void WndProc(ref Message m)
{
if (m.Msg == WM_NCLBUTTONDBLCLK)
{
return;
}
if (m.Msg == WM_NCHITTEST)
{
base.WndProc(ref m);
if (m.Result == HTCLIENT)
{
m.HWnd = this.Handle;
m.Result = HTCAPTION;
}
return;
}
base.WndProc(ref m);
}
#endregion
