C#游戏开发中快速的游戏循环的实现。参考《精通C#游戏编程》一书。

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows.Forms;using System.Runtime.InteropServices;namespace GameLoop{    [StructLayout(LayoutKind.Sequential)]    public struct Message    {        public IntPtr hWnd;        public Int32 msg;        public IntPtr wParam;        public IntPtr lParam;        public uint time;        public System.Drawing.Point p;    }    public class FastLoop    {        [System.Security.SuppressUnmanagedCodeSecurity]        [DllImport("User32.dll", CharSet = CharSet.Auto)]        public static extern bool PeekMessage(            out Message msg,            IntPtr hWnd,            uint messageFilterMin,            uint messageFilterMax,            uint flags);        PreciseTimer _timer = new PreciseTimer();        public delegate void LoopCallback();        LoopCallback _callback;        public FastLoop(LoopCallback callback)        {            _callback = callback;            Application.Idle += new EventHandler(OnApplicationEnterIdle);        }        void OnApplicationEnterIdle(object sender, EventArgs e)        {            while (IsAppStillIdle())            {                _callback();            }        }        private bool IsAppStillIdle()        {            Message msg;            return !PeekMessage(out msg, IntPtr.Zero, 0, 0, 0);        }    }}
