本文实例讲述了C#获取机器码的方法。分享给大家供大家参考，具体如下：
using System.Runtime.InteropServices;
using System.Management;
using System;
public class HardwareInfo
{
//取机器名
public string GetHostName()
{
return System.Net.Dns.GetHostName();
}
//取CPU编号
public String GetCpuID()
{
try
{
ManagementClass mc = new ManagementClass( "Win32_Processor" );
ManagementObjectCollection moc = mc.GetInstances();
String strCpuID = null ;
foreach ( ManagementObject mo in moc )
{
strCpuID = mo.Properties[ "ProcessorId" ].Value.ToString();
break ;
}
return strCpuID;
}
catch
{
return "" ;
}
} //end method
//取第一块硬盘编号
public String GetHardDiskID()
{
try
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher( "SELECT * FROM Win32_PhysicalMedia" );
String strHardDiskID = null ;
foreach (ManagementObject mo in searcher.Get())
{
strHardDiskID = mo[ "SerialNumber" ].ToString().Trim();
break ;
}
return strHardDiskID ;
}
catch
{
return "" ;
}
} //end
