直接贴代码：

复制代码 代码如下:

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();

} //www.heatpress123.net

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：

复制代码 代码如下:

static void Main(string[] args)

{

Console.WriteLine(OSInfoMation.GetOsVersion());

Console.ReadLine();

}
