【C#】设置有线网卡IP地址，子网掩码，网关，DNS

方法

    public partial class ComputerInfo{/// <summary>/// 设置IP地址，子网掩码，网关，DNS/// </summary>public static List<NetworkAdapterInfo> SetIpAddressSubMaskDnsGeteway(string ipAddress, string subMask, string geteWay, string dnsMain, string dnsBackup){List<NetworkAdapterInfo> networkAdapterInfos = new List<NetworkAdapterInfo>();//var str = new StringBuilder();ManagementBaseObject inPar = null;ManagementBaseObject outPar = null;ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");ManagementObjectCollection moc = mc.GetInstances();foreach (ManagementObject mo in moc){//屏蔽代码，避免出现无法修改未连接的有线网卡驱动//if (!(bool)mo["IPEnabled"])//    continue;networkAdapterInfos.Add(new NetworkAdapterInfo(){Description = mo["Description"].ToString(),IPEnabled = mo["IPEnabled"].ToString(),});//判断有线网卡var description = mo["Description"].ToString();//有线网卡//Realtek PCIe GbE Family Controller//无线网卡//Qualcomm QCA9565 802.11b/g/n Wireless Adapter//Realtek RTL8852AE WiFi 6 802.11ax PCle Adapter//Intel(R) Wi-Fi 6AX201 160MHzif (description.Contains("PCI") && new List<string>() { "Wireless", "WiFi", "Wi-Fi", "WLAN" }.Exists(w => description.Contains(w)) == false){//设置ip地址和子网掩码 inPar = mo.GetMethodParameters("EnableStatic");inPar["IPAddress"] = new string[] { ipAddress };inPar["SubnetMask"] = new string[] { subMask };outPar = mo.InvokeMethod("EnableStatic", inPar, null);//设置网关地址 inPar = mo.GetMethodParameters("SetGateways");inPar["DefaultIPGateway"] = new string[] { geteWay };outPar = mo.InvokeMethod("SetGateways", inPar, null);//设置DNS inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");inPar["DNSServerSearchOrder"] = new string[] { dnsMain, dnsBackup };outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);}//foreach (var item in mo.Properties)//{//    str.Append($"{item.Name}:{item.Value}\r\n");//}}//var info = str.ToString();return networkAdapterInfos;}}

例子

var networkAdapterInfos = ComputerInfo.SetIpAddressSubMaskDnsGeteway("192.168.11.20", "255.255.255.0", "192.168.11.1", "192.168.11.1", "8.8.8.8");
