[System.Runtime.InteropServices.DllImport("kernel32.dll")]        public static extern bool SetProcessWorkingSetSize(IntPtr proc, int min, int max);        public void FlushMemory()        {            GC.Collect();            GC.WaitForPendingFinalizers();            if (Environment.OSVersion.Platform == PlatformID.Win32NT)            {                SetProcessWorkingSetSize(System.Diagnostics.Process.GetCurrentProcess().Handle, -1, -1);            }        } 用法:只需要在你希望释放的时候调用FlushMemory()即可..
