1.PC平台

[StructLayout(LayoutKind.Sequential,Pack =1)]
        public struct MEMORYSTATUSEX
        {
            public uint dwLength;
            public uint dwMemoryLoad;
            //系统内存总量
            public ulong ullTotalPhys;
            //系统可用内存
            public ulong ullAvailPhys;
            public ulong ullTotalPageFile;
            public ulong ullAvailPageFile;
            public ulong ullTotalVirtual;
            public ulong ullAvailVirtual;
            public ulong ullAvailExtendedVirtual;
        }
    
        //extern  调用 其他平台 dll 关键字
        [DllImport("kernel32.dll")]
        protected static extern void GlobalMemoryStatus(ref MEMORYSTATUSEX lpBuff);
       
    
        /// <summary>
        /// 获取可用内存
        /// PC
        /// </summary>
        /// <returns></returns>
        protected ulong GetWinAvailMemory()
        {
            MEMORYSTATUSEX ms = new MEMORYSTATUSEX();
            ms.dwLength = 64;
            GlobalMemoryStatus(ref ms);
            return ms.ullAvailPhys;
        }
    
        /// <summary>
        /// 获取总内存
        /// PC
        /// </summary>
        /// <returns></returns>
        protected ulong GetWinTotalMemory()
        {
            MEMORYSTATUSEX ms = new MEMORYSTATUSEX();
            ms.dwLength = 64;
            GlobalMemoryStatus(ref ms);
            return ms.ullTotalPhys;
        }
    
        /// <summary>
        /// 返回应用使用的内存
        /// PC
        /// </summary>
        /// <returns></returns>
        protected long GetWinUsedMemory()
        {
            return UnityEngine.Profiling.Profiler.GetTotalReservedMemoryLong();
        }

内存快爆掉了。。。。

2.Android端

//当前系统可用内存
      ActivityManager am = 
                    (ActivityManager)m_Activity.getSystemService(Context.ACTIVITY_SERVICE);
      MemoryInfo mi= new MemoryInfo();
      am.getMemoryInfo(mi);
      return mi.availMem;

//当前系统总内存
       return  GetTotalMemory();

//应用所占内存
        Debug.MemoryInfo memoryInfo=new Debug.MemoryInfo();
        Debug.getMemoryInfo(memoryInfo);
        return  memoryInfo.getTotalPss()*1024;

3.IOS 回头更新
