C#编程修改本机的IP，网关等

这个小程序主要使用了System.Management 中的ManagementClass，ManagementObjectCollection，　ManagementObject等来获取系统的信息，并进行相应的设置，在.NET中都是相当简单的，只用调用相应的函数就可以了，这里主要使用了网卡信息察看和设置。对其他硬件信息的管理也是差不多的，有需要的朋友可以察看

ManagementBaseObject inPar = null;


ManagementBaseObject outPar = null;


ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");


ManagementObjectCollection moc = mc.GetInstances();


foreach( ManagementObject mo in moc )






{


if( ! (bool) mo[ "IPEnabled" ] )


continue;





//设置ip地址和子网掩码


inPar = mo.GetMethodParameters( "EnableStatic" );




inPar["IPAddress"] = new string[]
