C#获取系统版本信息

 直接贴代码：

 public class OSInfoMation
    {
        public static string OSBit()
        {
            try
            {
                ConnectionOptions oConn = new ConnectionOptions();

                System.Management.ManagementScope managementScope = new System.Management.ManagementScope("\\\\localhost", oConn);

                System.Management.ObjectQuery objectQuery = new System.Management.ObjectQuery("select AddressWidth from Win32_Processor");

                ManagementObjectSearcher moSearcher = new ManagementObjectSearcher(managementScope, objectQuery);

                ManagementObjectCollection moReturnCollection = null;

                string addressWidth = null;

                moReturnCollection = moSearcher.Get();
                
                foreach (ManagementObject oReturn in moReturnCollection)
                {
                    addressWidth = oReturn["AddressWidth"].ToString();
                }
                return addressWidth;
            }
            catch
            {
                return "获取错误";
            }

        }

        public static string GetOsVersion()
        {
            string osBitString = OSBit();

            string osVersionString = Environment.OSVersion.ToString();

            return string.Format(@"系统：{0}。位：{1}", osVersionString, osBitString);
        }
    }

调用：

        static void Main(string[] args)
        {
            Console.WriteLine(OSInfoMation.GetOsVersion());

            Console.ReadLine();
        }

结果：

系统：Microsoft Windows NT 5.1.2600 Service Pack 3。位：32
