设置本机IP地址

[wkzjl]

请问设置本机IP地址。并检查没有和距域网的其它IP地址重复！！！

看看system.net.dns类有没有该功能

怎么使用这个类啊

[haoliqi]

/// <code>
/// ArLi.CommonPrj.ChangeIP o = new ArLi.CommonPrj.ChangeIP();
/// string[] ipList = new string[]{"192.168.0.253","192.168.0.250"};
/// string[] subnetList = new string[]{"255.255.255.0","255.255.255.0"};
/// o.ChangeTo(ipList,subnetList);
/// </code>
试了一下,没有成功!是需要重新启动吗

好像System中没有Management吧
