在Vista系統以後,微軟爲窗體程序提供了Aero磨砂的效果,以下圖。那麼用C#如
何來實現這種磨砂效果呢?api
代碼:ide
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(); //直接添加代碼 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); } //直接添加代碼 protected override void OnPaintBackground(PaintEventArgs e) { base.OnPaintBackground(e); if (DwmIsCompositionEnabled()) { e.Graphics.Clear(Color.Black); } } public Form1() { InitializeComponent(); } } }
這中效果的實現主要是調用了系統的dwmapi.dll。this
dwmapi.dll是Microsoft Desktop Window Manager API(桌面窗口管理器DWM 的公用界面)的動態連接庫,正常文件,主要用做桌面效果的api。spa
DWM 是一種新界面,在除 Windows Vista Home Basic 以外的全部 Windows Vista 版本中均提供 DWM 界面。因此這種效果只能在Vista以後的系統中使用。orm
