首先, 调用系统 API, 这里如果要引用神马的, 就不一一列出了, 大家自己引用一下.

复制代码 代码如下:

[StructLayout(LayoutKind.Sequential)]

public struct MARGINS

{

public int Left;

public int Right;

public int Top;

public int Bottom;

}

[DllImport("dwmapi.dll", PreserveSig = false)]

public static extern void DwmExtendFrameIntoClientArea

(IntPtr hwnd, ref MARGINS margins);

[DllImport("dwmapi.dll", PreserveSig = false)]

public static extern bool DwmIsCompositionEnabled();

然后重写两个事件:

复制代码 代码如下:

protected override void OnLoad(EventArgs e)

{

if (DwmIsCompositionEnabled())

{

MARGINS margin = new MARGINS();

margin.Right = margin.Left = margin.Bottom = margin.Top = -1;

DwmExtendFrameIntoClientArea(this.Handle, ref margin);

}

base.OnLoad(e);

}

protected override void OnPaintBackground(PaintEventArgs e)

{

base.OnPaintBackground(e);

if (DwmIsCompositionEnabled())

{

e.Graphics.Clear(Color.Black);

}

}

最后.. 木有了, F5 运行吧~
