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
