C# 内存回收

如下示例代码是调用win32底层操作，实现内存的回收。       

 

[DllImport("kernel32.dll", EntryPoint = "SetProcessWorkingSetSize")]

        public static extern int SetProcessWorkingSetSize(IntPtr process, int minSize, int maxSize);

        /// <summary>

        /// 释放内存

        /// </summary>

        public static void ClearMemory()

        {

            GC.Collect();

            GC.WaitForPendingFinalizers();

            if (Environment.OSVersion.Platform == PlatformID.Win32NT)

            {

                SetProcessWorkingSetSize(System.Diagnostics.Process.GetCurrentProcess().Handle, -1, -1);

            }

        }
