代码如下：

        /// <summary>
        /// 获取系统内存大小
        /// </summary>
        /// <returns>内存大小（单位M）</returns>
        private static int GetPhisicalMemory()
        {
            ManagementObjectSearcher searcher = new ManagementObjectSearcher();   //用于查询一些如系统信息的管理对象
            searcher.Query = new SelectQuery("Win32_PhysicalMemory ", "", new string[] { "Capacity" });//设置查询条件
            ManagementObjectCollection collection = searcher.Get();   //获取内存容量
            ManagementObjectCollection.ManagementObjectEnumerator em = collection.GetEnumerator();

            long capacity = 0;
            while (em.MoveNext())
            {
                ManagementBaseObject baseObj = em.Current;
                if (baseObj.Properties["Capacity"].Value != null)
                {
                    try
                    {
                        capacity += long.Parse(baseObj.Properties["Capacity"].Value.ToString());
                    }
                    catch
                    {
                        return 0;
                    }
                }
            }
            return (int)(capacity / 1024 / 1024);
        }
