获取Windows系统位数

直接上代码

public static string Distinguish64or32System()
        {
            try
            {
                string addressWidth = String.Empty;
                ConnectionOptions mConnOption = new ConnectionOptions();
                ManagementScope mMs = new ManagementScope("\\\\localhost", mConnOption);
                ObjectQuery mQuery = new ObjectQuery("select AddressWidth from Win32_Processor");
                ManagementObjectSearcher mSearcher = new ManagementObjectSearcher(mMs, mQuery);
                ManagementObjectCollection mObjectCollection = mSearcher.Get();
                foreach (ManagementObject mObject in mObjectCollection)
                {
                    addressWidth = mObject["AddressWidth"].ToString();
                }
                if (addressWidth == "32")
                {
                    addressWidth = "86";
                }
                return “x”+ addressWidth;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
                return String.Empty;
            }
        }

上面方法将返回"x86"或"x64",很简单，直接拿去用吧！
