C#网络适配器简单 *** 作

概述网络的相关设置在项目开发中有较多的应用，有时候需要在项目中对网络信息进行相关设置。

网络的相关设置在项目开发中有较多的应用，有时候需要在项目中对网络信息进行相关设置。

现在提供提供几种相关的辅助方法类。

(1).IP地址

/// <summary>  /// IP地址  /// </summary>  public string IpAddress  {   get   {    string ipAddress;    var address = GetAddress();    if (address == null)    {     ipAddress = string.Empty;    }    else    {     ipAddress = address.Address.ToString();    }    return ipAddress;   }   set { if (value == null) throw new ArgumentNullException(nameof(value)); }  }

(2).网关地址

  /// <summary>  /// 网关地址  /// </summary>  public string Getway  {   get   {        string getway;    if (Getwaryes != null && Getwaryes.Count > 0)    {     getway = Getwaryes[0].Address.ToString() == "0.0.0.0" ? "" : Getwaryes[0].Address.ToString();     }    else    {     getway =string.Empty;    }    return getway;   }   set { if (value == null) throw new ArgumentNullException(nameof(value)); }  }

(3). DHCP服务器地址

  /// <summary>  /// DHCP服务器地址  /// </summary>  public string Dhcpserver  {   get   {    string dhcpserver;    if (DhcpserverAddresses != null && DhcpserverAddresses.Count > 0)    {     dhcpserver = DhcpserverAddresses[0].ToString();    }    else    {     dhcpserver = string.Empty;    }    return dhcpserver;   }   set { if (value == null) throw new ArgumentNullException(nameof(value)); }  }

(4).MAC地址

(9).是否是IP地址

  /// <summary>  /// 是否是IP地址  /// </summary>  /// <param name="ipAddress"></param>  /// <returns></returns>  public bool IsIPAddress(string ipAddress)  {   const string regexStr = @"^(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])$";   var regex = System.Text.RegularExpressions.Regex.Match(ipAddress,regexStr);   return regex.Success;  }

(10).启用DHCP服务

  /// <summary>  /// 启用DHCP服务  /// </summary>  public bool EnableDhcp()  {   var wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");   var moc = wmi.GetInstances();   foreach (var o in moc)   {    var mo = (ManagementObject) o;    if (!(bool)mo["IPEnabled"])     continue;    if (mo["SettingID"].ToString() != NetworkInterfaceID) continue;    mo.InvokeMethod("SetDNSServerSearchOrder",null);    mo.InvokeMethod("EnableDHCP",null);   }   //查询现适配器接口信息   var networkAdapter = new NetworkAdapterUtil().GetNeworkAdapterByNetworkInterfaceID(NetworkInterfaceID);    return networkAdapter != null && networkAdapter.IsDhcpEnabled;  }

(11).设置IP地址,子网掩码，网关,DNS

 /// <summary>  /// 设置IP地址,DNS,/// </summary>  public bool SetIpAddressSubMaskDnsGetway(string ipAddress,string subMask,string getWay,string dnsMain,string dnsBackup)  {   string[] dnsArray;   if (string.IsNullOrEmpty(dnsBackup))   {    dnsArray = new[] { dnsMain };   }   else   {    dnsArray = new[] { dnsMain,dnsBackup };   }   return SetIpAddress(new[] { ipAddress },new[] { subMask },new[] { getWay },dnsArray);  }  /// <summary>  /// 设置IP地址和子网掩码  /// </summary>  public bool SetIpAddressAndSubMask(string ipAddress,string subMask)  {   return SetIpAddress(new[] { ipAddress },null,null);  }  /// <summary>  /// 设置IP网关  /// </summary>  public bool SetGetWayAddress(string getWay)  {   return SetIpAddress(null,null);  }

(12).设置主,备份DNS地址

  /// <summary>  /// 设置主,备份DNS地址  /// </summary>  public bool SetDnsAddress(string dnsMain,dnsBackup };   }   return SetIpAddress(null,dnsArray);  }

(14).检查设置IP地址,如果返回空，表示检查通过，为了方便返回就字符串了

  /// <summary>  /// 检查设置IP地址,如果返回空，表示检查通过，为了方便返回就字符串了，没用枚举了  /// </summary>  /// <param name="ipAddress"></param>  /// <param name="subMask"></param>  /// <param name="getWay"></param>  /// <param name="dnsMain"></param>  /// <param name="dnsBackup"></param>  /// <returns></returns>  public string IsIPAddress(string ipAddress,string dnsBackup)  {   if (!string.IsNullOrEmpty(ipAddress))   {    if (!IsIPAddress(ipAddress)) return "IP地址格式不对";   }   if (!string.IsNullOrEmpty(subMask))   {    if (!IsIPAddress(subMask)) return "子网掩码格式不对";   }   if (!string.IsNullOrEmpty(getWay))   {    if (!IsIPAddress(getWay)) return "网关地址格式不对";   }   if (!string.IsNullOrEmpty(dnsMain))   {    if (!IsIPAddress(dnsMain)) return "主DNS地址格式不对";   }   if (string.IsNullOrEmpty(dnsBackup)) return "";   return !IsIPAddress(dnsBackup) ? "备用DNS地址格式不对" : "";  }

(15).设置IP地址

  /// <summary>  /// 设置IP地址  /// </summary>  /// <param name="ip"></param>  /// <param name="submask"></param>  /// <param name="getway"></param>  /// <param name="dns"></param>  private bool SetIpAddress(IEnumerable ip,IEnumerable submask,IEnumerable getway,IEnumerable dns)  {   var wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");   var moc = wmi.GetInstances();   foreach (var o in moc)   {    var mo = (ManagementObject) o;    if (!(bool)mo["IPEnabled"])     continue;    if (NetworkInterfaceID != mo["SettingID"].ToString()) continue;    ManagementBaSEObject inPar;    ManagementBaSEObject outPar;    string str = null;    if (ip != null && submask != null)    {     inPar = mo.getmethodParameters("EnableStatic");     inPar["IPAddress"] = ip;     inPar["subnetMask"] = submask;     outPar = mo.InvokeMethod("EnableStatic",inPar,null);     if (outPar != null) str = outPar["returnvalue"].ToString();     return (str=="0"||str=="1");     //获取 *** 作设置IP的返回值， 可根据返回值去确认IP是否设置成功。 0或1表示成功    }    if(getway!=null)    {     inPar = mo.getmethodParameters("SetGateways");     inPar["DefaultIPGateway"] = getway;     outPar = mo.InvokeMethod("SetGateways",null);     if (outPar != null) str = outPar["returnvalue"].ToString();     return (str == "0" || str == "1");    }    if (dns == null) continue;    inPar = mo.getmethodParameters("SetDNSServerSearchOrder");    inPar["DNSServerSearchOrder"] = dns;    outPar = mo.InvokeMethod("SetDNSServerSearchOrder",null);    if (outPar != null) str = outPar["returnvalue"].ToString();    return (str == "0" || str == "1");   }   return false;  }
