在C＃中更改IP地址

Question

我有一个需要通过UDP连接连接到另一台计算机的c＃程序。为了执行此操作，我需要临时更改我的计算机上网卡的IP地址，以便他们可以相互交谈。我可以做到这一点很好。但是，当我完成后，我想将我的IP地址恢复到之前的状态;即自动获取IP地址。

有人可以告诉我如何改变我的设置回到他们以前？

感谢，

菲尔

你可能要检查这个项目SwitchNetConfig。

，你是关心如何更改IP的部分：

public static void SetIP(string nicName, string IpAddresses, 
    string SubnetMask, string Gateway, string DnsSearchOrder) 
{ 
    ManagementClass mc = new ManagementClass(
    "Win32_NetworkAdapterConfiguration"); 
    ManagementObjectCollection moc = mc.GetInstances(); 

    foreach(ManagementObject mo in moc) 
    { 
    // Make sure this is a IP enabled device. 

    // Not something like memory card or VM Ware 

    if(mo["IPEnabled"] as bool) 
    { 
     if(mo["Caption"].Equals(nicName)) 
     { 

     ManagementBaseObject newIP = 
      mo.GetMethodParameters("EnableStatic"); 
     ManagementBaseObject newGate = 
      mo.GetMethodParameters("SetGateways"); 
     ManagementBaseObject newDNS = 
      mo.GetMethodParameters("SetDNSServerSearchOrder"); 

     newGate[ "DefaultIPGateway" ] = new string[] { Gateway }; 
     newGate[ "GatewayCostMetric" ] = new int[] { 1 }; 

     newIP[ "IPAddress" ] = IpAddresses.Split(','); 
     newIP[ "SubnetMask" ] = new string[] { SubnetMask }; 

     newDNS[ "DNSServerSearchOrder" ] = DnsSearchOrder.Split(','); 

     ManagementBaseObject setIP = mo.InvokeMethod( 
      "EnableStatic", newIP, null); 
     ManagementBaseObject setGateways = mo.InvokeMethod( 
      "SetGateways", newGate, null); 
     ManagementBaseObject setDNS = mo.InvokeMethod( 
      "SetDNSServerSearchOrder", newDNS, null); 

     break; 
     } 
    } 
    } 
}
