WMI設置有線網卡IP地址

1、經過WMI獲取物理適配器序號

NetEnabled: 是否啓用了適配器，True爲啓用，False爲禁用;
PhysicalAdapter: 適配器是否物理或邏輯適配器,True爲物理，False爲邏輯;

 public static List<int> GetUseIndex()
        {
            List<int> list = new List<int>();
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapter");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                bool p1 = Convert.ToBoolean(mo["NetEnabled"]);
                bool p2 = Convert.ToBoolean(mo["PhysicalAdapter"]);
                if (p1 && p2)
                {
                    list.Add(Convert.ToInt32((mo["Index"])));
                }
            }
            return list;
        }

 

2、過濾虛擬網卡、無線網卡

經過「Characteristics」這個值來肯定網卡的類型是虛擬網卡仍是物理網卡。Characteristics 值在註冊表在HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\【鏈接索引號】\下，在windows中，Characteristics 的取值以下，Characteristics項能夠有1個或多個以下的值(多值應計算總和)：【備註：在Windows7和Windows10下確認，Characteristics爲dword，不可能多個值，這裏的多個值，計算總和暫時未知。】

0x1	NCF_VIRTUAL	說明組件是個虛擬適配器
0x2	NCF_SOFTWARE_ENUMERATED	說明組件是一個軟件模擬的適配器
0x4	NCF_PHYSICAL	說明組件是一個物理適配器
0x8	NCF_HIDDEN	說明組件不顯示用戶接口
0x10	NCF_NO_SERVICE	說明組件沒有相關的服務(設備驅動程序)
0x20	NCF_NOT_USER_REMOVABLE	說明不能被用戶刪除(例如，經過控制面板或設備管理器)
0x40	NCF_MULTIPORT_INSTANCED_ADAPTER	說明組件有多個端口，每一個端口做爲單獨的設備安裝。每一個端口有本身的hw_id(組件ID) 並可被單獨安裝，這隻適合於EISA適配器
0x80	NCF_HAS_UI	說明組件支持用戶接口(例如，Advanced Page或Customer Properties Sheet)
0x400	NCF_FILTER	說明組件是一個過濾器

若是是物理網卡：Characteristics & NCF_PHYSICAL ==NCF_PHYSICAL

判斷有線網卡和無線網卡，註冊表路徑：HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\【鏈接索引號】\Ndi\Interfaces

路徑下的鍵值：LowerRange，若是Value包含wifi或者wlan，（驗證的兩臺設備Value=「wlan,ethernet,vwifi」），表示無線網卡，具體代碼以下：

        public static bool GetWiredIndex(ref int index, ref string msg)
        {
            try
            {
                List<int> allenable = GetUseIndex();
                if (allenable.Count == 0)
                {
                    msg = "未查找到有效網絡鏈接";
                    return false;
                }
                List<int> allReal = new List<int>();
                foreach (int ii in allenable)
                {
                    var vv = Convert.ToInt32(GetCharacteristics(@"SYSTEM\ControlSet001\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\000" + ii, "Characteristics"));
                    if ((vv & 0x4) == 0x4)//區分物理網卡、虛擬網卡
                    {
                        allReal.Add(ii);
                    }
                }
                if (allReal.Count == 0)
                {
                    msg = "未查找到有效物理網卡";
                    return false;
                }

                int rv = -1;
                foreach (int ii in allReal)
                {
                    var vv = GetCharacteristics(@"SYSTEM\ControlSet001\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\000" + ii + @"\Ndi\Interfaces", "LowerRange").ToString();
                    if (!vv.Contains("wifi") && !vv.Contains("wlan"))
                    {
                        rv = ii;
                        break;
                    }
                }
                if (rv == -1)
                {
                    msg = "未查找到有效有線網卡";
                    return false;
                }
                else
                {
                    index = rv;
                    return true;
                }
            }
            catch (Exception ex)
            {
                msg = ex.Message;
                return false;
            }
        }

        private static object GetCharacteristics(string name, string key)
        {
            object registData;
            using (RegistryKey hkml = Registry.LocalMachine)
            {
                RegistryKey software = hkml.OpenSubKey(name, true);
                registData = software.GetValue(key).ToString();
            }
            return registData;
        }

3、設置有線網卡IP、子網掩碼、網關、DNS

 public static bool SetWiredIP(int index, string ip, string subnetMask, string ipGateway, string dns)
        {
　　　　　　　　
            ManagementBaseObject inPar = null;
            ManagementBaseObject outPar = null;
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                if (Convert.ToInt32(mo["Index"]) == index)
                {
                    //設置ip地址和子網掩碼 
                    inPar = mo.GetMethodParameters("EnableStatic");
                    inPar["IPAddress"] = new string[] { ip };
                    inPar["SubnetMask"] = new string[] { subnetMask };
                    outPar = mo.InvokeMethod("EnableStatic", inPar, null);

                    //設置網關地址 
                    inPar = mo.GetMethodParameters("SetGateways");
                    inPar["DefaultIPGateway"] = new string[] { ipGateway };
                    outPar = mo.InvokeMethod("SetGateways", inPar, null);

                    //設置DNS 
                    inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
                    inPar["DNSServerSearchOrder"] = new string[] { dns };
                    outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
                    return true;
                }
            }
            return false;
        }
