C#判断操作系统的位数

      在.net 4.5中，判断操作系统不用再写方法去判断了，有直接可以利用的属性了哦，如下所示：

Environment.Is64BitProcess 属性

.NET Framework 4.5       

 

确定当前进程是否为 64 位进程。

 

    当然如果是用的.net 4.5以前的童鞋也不必担心，同样也可以用以下的方法来实现判断系统位数。

    private 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();
                }
                return addressWidth;
            }
            catch (Exception ex)
            {
              
                return String.Empty;
            }
        }
