在 C# 中更改网络配置

Question

我正在尝试编写一个简单的程序来更改 C# 中的 IP 参数。我使用这段代码：如何使用 C# 代码更改网络设置（IP 地址、DNS、WINS、主机名）来 执行它，并制作了我自己的方法：

public void changerip(string adresse, string NIC)
{
    ManagementObjectCollection objMOC = objMC.GetInstances();
    foreach (ManagementObject objMO in objMOC)
    {

        if (objMO["Caption"].Equals(NIC))
        {
            try
            {
                if (adresse != "0")
                {
                    ManagementBaseObject setIP;
                    ManagementBaseObject newIP =
                        objMC.GetMethodParameters("EnableStatic");

                    newIP["IPAddress"] = new string[] { "192.168." + adresse + ".50" };
                    newIP["SubnetMask"] = new string[] { "255.255.255.0" };
                    setIP = objMO.InvokeMethod("EnableStatic", newIP, null);

                    ManagementBaseObject setGateway;
                    ManagementBaseObject newGateway =
                    objMO.GetMethodParameters("SetGateways");
                    newGateway["DefaultIPGateway"] = new string[] { "192.168." + adresse + ".254" };
                    newGateway["GatewayCostMetric"] = new int[] { 1 };
                    setGateway = objMO.InvokeMethod("SetGateways", newGateway, null);

                    ManagementBaseObject newDNS =
                    objMO.GetMethodParameters("SetDNSServerSearchOrder");
                    newDNS["DNSServerSearchOrder"] = "192.168.1.24,192.168.1.2".Split(',');
                    ManagementBaseObject setDNS =
                    objMO.InvokeMethod("SetDNSServerSearchOrder", newDNS, null);
                }
                else
                {
                    ManagementBaseObject newDNS = objMO.GetMethodParameters("SetDNSServerSearchOrder");
                    newDNS["DNSServerSearchOrder"] = null;
                    ManagementBaseObject enableDHCP = objMO.InvokeMethod("EnableDHCP", null, null);
                    ManagementBaseObject setDNS = objMO.InvokeMethod("SetDNSServerSearchOrder", newDNS, null);
                    //Save all Gateways into an array
                    string[] gateways = (string[])objMO["DefaultIPGateway"];

                    ManagementBaseObject newIP = objMO.GetMethodParameters("EnableStatic");
                    ManagementBaseObject newGate = objMO.GetMethodParameters("SetGateways");

                    //Set last value of the array(always the Gateway recived by DHCP) as the default Gateway
                    newGate["DefaultIPGateway"] = new string[] { gateways[gateways.Length - 1] };
                    newGate["GatewayCostMetric"] = new int[] { 1 };
                }
            }
            catch (Exception Ex)
            {
                MessageBox.Show(Ex.Message);
            }
        }
    }
}

它在 Windows XP 中运行良好，但在 Windows 7（入门版或专业版）中不起作用。我没有出现任何异常，也没有来自操作系统的错误/安全消息。

有人知道发生了什么吗？

对我来说似乎是一个凭据问题。您应该以管理权限运行该程序。您可以通过简单地右键单击 exe 并单击“以管理员身份运行”来完成此操作。
