NET反编译出来的C#关键代码
破解 一个程序 反编译出来的关键代码 ，但看不懂代码 中flag这个是怎样判断 的，求解答下，先谢了。原贴是这里http://www.52pojie.cn/thread-234462-4-1.html

敢换个背景色吗？ 绿色背景看的好辛苦啊 绿色背景挺好的啊 依然看不懂是什么
程序哪来 我给你秒做一个注册机 前两句摘取MSDN，其他注释自己分析哈。新手见谅！:$qqq
NetworkInterface[] allNetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();//返回描述本地计算机上的网络接口的对象。//包含描述可用网络接口的对象的 NetworkInterface 数组，如果没有检测到接口，则为空数组。
int num = 0;
string text = null;
NetworkInterface[] array = allNetworkInterfaces;
checked//开始检测
{
bool flag;
for (int i = 0; i < array.Length; i++)
{
NetworkInterface networkInterface = array;//可能是多个对象或者一个也没有
num++;
flag = (num == 1);//如果num等于1真，反之为假
if (flag)
{
text = networkInterface.GetPhysicalAddress().ToString();//获取MAC物理地址。
}
}
}
简单说flag用来获取MAC地址的。 zjs 发表于 2014-1-28 01:17 static/image/common/back.gif

NetworkInterface[] al ...
那这么说不是注册算法啊，麻烦 了！！！！
