C#实现具有Aero效果的窗体

using System.Runtime.InteropServices;//引用,放在哪不用说了吧....

[DllImport("dwmapi.dll")]
public static extern int DwmExtendFrameIntoClientArea(IntPtr hWnd, ref MARGINS pMarinset);
[StructLayout(LayoutKind.Sequential)]
public struct MARGINS
{
    public int Right;
    public int left;
    public int Top;
    public int Bottom;
}

private void Form1_Load(object sender, EventArgs e)
{
    this.BackgroundImage = null;
    MARGINS margins = new MARGINS();
    margins.left = -1;
    margins.Right = -1;
    margins.Top = -1;
    margins.Bottom = -1;
    IntPtr hwnd = Handle;
    int result = DwmExtendFrameIntoClientArea(hwnd, ref margins);
    this.BackColor = Color.Black;
    this.label1.Text = "。。。";
    this.label1.BackColor = Color.Transparent;
    this.label1.ForeColor = Color.White;
}
