修改注册表中本地连接的Ip和网卡地址C#.docx

1、修改注册表中本地连接的Ip和网卡地址C#修改注册表中本地连接的Ip和网卡地址(C#)语言c# ,运行需要.net framework 2.0在很多行业或公司，会通过限制ip的方法，使局域网内一部分ip可以上外网。本方案通过修改ip和网卡地址达到在别人不知不觉地情况下共用一个ip上网。=代码如下: =using system;using system.collections.generic;using ponentmodel;using system.data;using system.drawing;using system.text;using system.windows.forms;us
