如何使用 C# 中的代码更改网络设置(IP 地址、DNS、WINS、主机名) [英] How can you change Network settings (IP Address, DNS, WINS, Host Name) with code in C#

问题描述

我正在为一台用作其他机器备份的机器开发一个向导.当它替换现有机器时，它需要设置其 IP 地址、DNS、WINS 和主机名以匹配被替换的机器.

I am developing a wizard for a machine that is to be used as a backup of other machines. When it replaces an existing machine, it needs to set its IP address, DNS, WINS, and host name to match the machine being replaced.

.net (C#) 中是否有允许我以编程方式执行此操作的库?

Is there a library in .net (C#) which allows me to do this programatically?

有多个 NIC，每个都需要单独设置.

There are multiple NICs, each which need to be set individually.

谢谢TimothyP 为您的示例.它让我在正确的轨道上前进，快速的回复很棒.

Thank you TimothyP for your example. It got me moving on the right track and the quick reply was awesome.

谢谢 balexandre.你的代码是完美的.我很着急，已经改编了 TimothyP 链接到的示例，但我希望早点拥有您的代码.

Thanks balexandre. Your code is perfect. I was in a rush and had already adapted the example TimothyP linked to, but I would have loved to have had your code sooner.

我还开发了一个使用类似技术来更改计算机名称的例程.我会在未来发布，所以如果你想订阅这个问题 RSS feed通知了更新.我可能会在今天晚些时候或在稍作清理后在星期一拿到它.

I've also developed a routine using similar techniques for changing the computer name. I'll post it in the future so subscribe to this questions RSS feed if you want to be informed of the update. I may get it up later today or on Monday after a bit of cleanup.

几分钟就搞定了:

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");
      ManagementObjectCollection objMOC = objMC.GetInstances();

      foreach (ManagementObject objMO in objMOC)
      {
        if ((bool)objMO["IPEnabled"])
        {
          ManagementBaseObject setGateway;
          ManagementBaseObject newGateway =
            objMO.GetMethodParameters("SetGateways");

          newGateway["DefaultIPGateway"] = new string[] { gateway };
          newGateway["GatewayCostMetric"] = new int[] { 1 };

          setGateway = objMO.InvokeMethod("SetGateways", newGateway, null);
        }
      }
    }

    public void setDNS(string NIC, string DNS)
    {
      ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
      ManagementObjectCollection objMOC = objMC.GetInstances();

      foreach (ManagementObject objMO in objMOC)
      {
        if ((bool)objMO["IPEnabled"])
        {
          // if you are using the System.Net.NetworkInformation.NetworkInterface
          // you'll need to change this line to
          // if (objMO["Caption"].ToString().Contains(NIC))
          // and pass in the Description property instead of the name 
          if (objMO["Caption"].Equals(NIC))
          {
            ManagementBaseObject newDNS =
              objMO.GetMethodParameters("SetDNSServerSearchOrder");
            newDNS["DNSServerSearchOrder"] = DNS.Split(',');
            ManagementBaseObject setDNS =
              objMO.InvokeMethod("SetDNSServerSearchOrder", newDNS, null);
          }
        }
      }
    }

    public void setWINS(string NIC, string priWINS, string secWINS)
    {
      ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
      ManagementObjectCollection objMOC = objMC.GetInstances();

      foreach (ManagementObject objMO in objMOC)
      {
        if ((bool)objMO["IPEnabled"])
        {
          if (objMO["Caption"].Equals(NIC))
          {
            ManagementBaseObject setWINS;
            ManagementBaseObject wins =
            objMO.GetMethodParameters("SetWINSServer");
            wins.SetPropertyValue("WINSPrimaryServer", priWINS);
            wins.SetPropertyValue("WINSSecondaryServer", secWINS);

            setWINS = objMO.InvokeMethod("SetWINSServer", wins, null);
          }
        }
      }
    } 
  }
}
