修改注册表中本地连接的Ip和网卡地址(C#).doc

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;using microsoft.win32;using system.windows;using system.management;using workinformation;using system.serviceprocess; namespace reworkmac{??? public partial class form1 : form??? {??????? public form1()??????? {??????????? initializecomponent();??????? } ??????? private void form1_load(object sender, eventargs e)??????? {??????????? listbox1.items.clear();??????????? registrykey macregistry = registry.localmachine.opensubkey(system).opensubkey(currentcontrolset).opensubkey(control).opensubkey(class).opensubkey({4d36e972-e325-11ce-bfc1-08002be10318});//mac的注册表建所在??????????? foreach (string mrk in macregistry.getsubkeynames())??????????? {??????????????? listbox1.items.add(mrk);??????????? }??????????? ipglobalproperties computerproperties = ipglobalproperties.getipglobalproperties();??????????? ??????????? textbox4.text = computerproperties.hostname;??????????? networkinterface[] nics = networkinterface.getallnetworkinterfaces();??????????? foreach (networkinterface adapter in nics)??????????? {??????????????? if (==本地连接)??????????????? {??????????????????? textbox2.text = adapter.description;??????????????????? textbox3.text = adapter.getphysicaladdress().tostring();??????????????????? textbox10.text = adapter.id;??????????????? }??????? //??????? listbox3.items.add(adapter.id+ 接口类型? +workinterfacetype.tostring());??????????? }??????????? /////////////////////////////////////////////////////////////////??????????? ///一下这一段有待以后研究，现在还没有看懂??????????? managementclass mc = new managementclass(win32_networkadapterconfiguration);??????????? managementobjectcollection moc = mc.getinstances();??????????? foreach (managementobject mo in mo
