C#获取CPU序列号机器码并生成注册码

本例用C#获取CPU序列号生成机器码，最后生成注册码，在软件注册的时候经常用到，效率还算可以。

using System.Management;//需要在项目中添加System.Management引用

disk.Get();
return disk.GetPropertyValue("VolumeSerialNumber").ToString();
}

strCpu = myObject.Properties["Processorid"].Value.ToString();
break;
}

}

public string getMNum()
{

return strMNum;
}
public int[] intCode = new int[127];//存储密钥
