Cha*_*ler 63 .net c# configuration networking
我正在为一台机器开发一个向导,用作其他机器的备份.当它替换现有机器时,需要设置其IP地址,DNS,WINS和主机名以匹配要更换的机器.
在.net(C#)中是否有一个库允许我以编程方式执行此操作？
有多个NIC,每个都需要单独设置.

谢谢TimothyP的例子.它让我在正确的轨道上移动,快速回复很棒.
谢谢balexandre.你的代码很完美.我很匆忙,并且已经修改了TimothyP链接的示例,但我希望能早点使用您的代码.
我还开发了一个例程,使用类似的技术来更改计算机名称.我将来会发布它,所以如果你想了解更新,请订阅这个问题RSS feed.我可能会在今天晚些时候或周一经过一些清理后得到它.

刚刚在几分钟内做到这一点:
using System;
using System.Management;
namespace WindowsFormsApplication_CS
{
class NetworkManagement
{
public void setIP(string ip_address, string subnet_mask)
{
ManagementClass objMC =
new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMC.GetInstances();
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);
}
}
}
public void setGateway(string gateway)
{
ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");

if (objMO["Caption"].Equals(NIC))
{
ManagementBaseObject newDNS =
objMO.GetMethodParameters("SetDNSServerSearchOrder");
newDNS["DNSServerSearchOrder"] = DNS.Split(',');
ManagementBaseObject setDNS =

将balexandre中的代码重构一点,以便处理对象并使用C#3.5+的新语言功能(Linq,var等).还将变量重命名为更有意义的名称.我还合并了一些函数,以便能够以更少的WMI交互进行更多配置.我删除了WINS代码,因为我不再需要配置WINS.如果需要,可以随意添加WINS代码.
对于任何人都喜欢使用重构/现代化代码的情况,我把它放回社区.

我喜欢WMILinq解决方案.虽然不完全是您的问题的解决方案,但请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);
}

更明确的解决方案是使用命令netsh更改 IP（或将其设置回 DHCP）
netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0
其中“本地连接”是网络适配器的名称。您可以在Windows网络连接中找到它，有时它只是简单地命名为“以太网”。
这里有两种设置IP的方法，也可以将IP设置回DHCP“自动获取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;
}
