在Vista系统之后，微软为窗体程序提供了Aero磨砂的效果，如下图。那么用C#如
何来实现这种磨砂效果呢？

代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Reflection;
using System.Runtime.InteropServices;//引用DLL申明



namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        //DLL申明
        [StructLayout(LayoutKind.Sequential)]
        public struct MARGINS
        {
            public int Left;
            public int Right;
            public int Top;
            public int Bottom;
        }

        //DLL申明
        [DllImport("dwmapi.dll", PreserveSig = false)]
        static extern void DwmExtendFrameIntoClientArea(IntPtr hwnd, ref MARGINS
        margins);

        //DLL申明
        [DllImport("dwmapi.dll", PreserveSig = false)]
        static extern bool DwmIsCompositionEnabled();

        //直接添加代码
        protected override void OnLoad(EventArgs e)
        {
            if (DwmIsCompositionEnabled())
            {
                MARGINS margins = new MARGINS();
                margins.Right = margins.Left = margins.Top = margins.Bottom =
        this.Width + this.Height;
                DwmExtendFrameIntoClientArea(this.Handle, ref margins);
            }
            base.OnLoad(e);
        }

        //直接添加代码
        protected override void OnPaintBackground(PaintEventArgs e)
        {
            base.OnPaintBackground(e);
            if (DwmIsCompositionEnabled())
            {
                e.Graphics.Clear(Color.Black);
            }
        }

        public Form1()
        {
            InitializeComponent();
        }
    }
}
