我开发了一台机器，将被用来作为其他计算机的备份向导。 当它取代现有的机器，它需要设定其IP地址，DNS，WINS和主机名匹配被替换的机器。
有没有在.net中（C＃）库，让我以编程方式做到这一点？
有多个网卡，每个需要单独设置。

感谢您TimothyP为你的榜样。 这让我感动在正确的轨道上，并快速回复是真棒。
感谢balexandre 。 您的代码是完美的。 我在匆忙和已经适应TimothyP挂例子，但我会喜欢有你的代码更快。
我一直在使用类似的技术来改变计算机名称也制定了程序。 我将它张贴在未来使订阅这个问题RSS源 ，如果你想告知的更新。 我可能有点清理后，在今天晚些时候或周一得到它。
就在几分钟内做出这样的：

foreach (ManagementObject objMO in objMOC)
{
if ((bool)objMO["IPEnabled"])
{
ManagementBaseObject setIP;
ManagementBaseObject newIP =
objMO.GetMethodParameters("EnableStatic");
newIP["IPAddress"] = new string[] { ip_address };
newIP["SubnetMask"] = new string[] { subnet_mask };
setIP = objMO.InvokeMethod("EnableStatic", newIP, null);
}

}
}
}
}
}
}
这样的对象被布置和的C＃3.5+新语言功能的使用（LINQ，VAR等）从balexandre一点重构的代码。 也改名为变量，以更有意义的名称。 我还合并了一些职能，能够做更多的配置较少的WMI互动。 我删除了WINS代码，我不需要再配置WINS。 随意如果你需要它添加WINS代码。
对于任何人的情况下喜欢用重构/现代化的代码，我把它放回社区在这里。

我希望你不介意我送你一个例子，但是这确实是一个很好的例子： http://www.codeproject.com/KB/cs/oazswitchnetconfig.aspx
我喜欢WMILinq解决方案。 虽然没有完全解决您的问题，在下面找到它的味道：
using (WmiContext context = new WmiContext(@"\\.")) {
context.ManagementScope.Options.Impersonation = ImpersonationLevel.Impersonate;
context.Log = Console.Out;
var dnss = from nic in context.Source<Win32_NetworkAdapterConfiguration>()
where nic.IPEnabled
select nic;
var ips = from s in dnss.SelectMany(dns => dns.DNSServerSearchOrder)
select IPAddress.Parse(s);
}

在C＃动态IP的变化是很容易...
请看下面的代码，并请访问： http://microsoftdotnetsolutions.blogspot.in/2012/12/dynamic-ip-change-in-c.html
现有的答案已经相当断码。 该DNS方法不会在所有的工作。 这里是我用来配置我的网卡的代码：

是建立在这里的其他答案的顶部稍微更简洁的例子。 我利用代码生成了与Visual Studio的运去大部分的额外调用代码，并取代它与类型化的对象，而不是。

这也许更清楚：

ManagementObjectCollection moc = managementClass.GetInstances();
foreach(ManagementObject mo in moc)

一个更为明确的解决方案是使用命令netsh改变IP（或设置回DHCP）
netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0
这里有两种方法来设置IP，并设置IP回DHCP“自动获得IP地址”
public bool SetIP(string networkInterfaceName, string ipAddress, string subnetMask, string gateway = null)
{
var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
var ipProperties = networkInterface.GetIPProperties();
var ipInfo = ipProperties.UnicastAddresses.FirstOrDefault(ip => ip.Address.AddressFamily == AddressFamily.InterNetwork);
var currentIPaddress = ipInfo.Address.ToString();
var currentSubnetMask = ipInfo.IPv4Mask.ToString();
var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;
if (!isDHCPenabled && currentIPaddress == ipAddress && currentSubnetMask == subnetMask)
return true; // no change necessary
var process = new Process
{
StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" static {ipAddress} {subnetMask}" + (string.IsNullOrWhiteSpace(gateway) ? "" : $"{gateway} 1")) { Verb = "runas" }
};
process.Start();
var successful = process.ExitCode == 0;
process.Dispose();
return successful;
}
public bool SetDHCP(string networkInterfaceName)
{
var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
var ipProperties = networkInterface.GetIPProperties();
var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;
if (isDHCPenabled)
return true; // no change necessary
var process = new Process
{
StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" dhcp") { Verb = "runas" }
};
process.Start();
var successful = process.ExitCode == 0;
process.Dispose();
return successful;
