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
/// <summary> /// mac地址 /// </summary> public string macaddres { get { string macaddress; if (macaddress == null) macaddress = string.empty; else if (macaddress.tostring().length == 12) { macaddress = macaddress.tostring().insert(4, "-").insert(9, "-"); } else { macaddress = macaddress.tostring(); } return macaddress; } set { if (value == null) throw new argumentnullexception(nameof(value)); } }
(5). 主dns地址
/// <summary> /// 主dns地址 /// </summary> public string dnsmain { get { var dnsmain =string.empty; if (dnsaddresses.count > 0) { if (isipaddress(dnsaddresses[0].tostring())) { dnsmain = dnsaddresses[0].tostring(); } } else { dnsmain =string.empty; } return dnsmain; } set { if (value == null) throw new argumentnullexception(nameof(value)); } }
(6).备用dns地址
/// <summary> /// 备用dns地址 /// </summary> public string dnsbackup { get { var dnsbackup = string.empty; if (dnsaddresses.count > 1) { if (isipaddress(dnsaddresses[1].tostring())) { dnsbackup = dnsaddresses[1].tostring(); } } else { dnsbackup = string.empty; } return dnsbackup; } set { if (value == null) throw new argumentnullexception(nameof(value)); } }
(7).子网掩码
/// <summary> /// 子网掩码 /// </summary> public string mask { get { string mask; var address = getaddress(); if (address == null) { mask = ""; } else { if (address.ipv4mask != null) { mask = address.ipv4mask.tostring(); } else { mask = "255.255.255.0"; } } return mask; } set { if (value == null) throw new argumentnullexception(nameof(value)); } }
(8).属性
/// <summary> /// dns集合 /// </summary> public ipaddresscollection dnsaddresses { get; set; } /// <summary> /// 网关地址集合 /// </summary> public gatewayipaddressinformationcollection getwaryes { get; set; } /// <summary> /// ip地址集合 /// </summary> public unicastipaddressinformationcollection ipaddresses { get; set; } /// <summary> /// dhcp地址集合 /// </summary> public ipaddresscollection dhcpserveraddresses { get; set; } /// <summary> /// 网卡mac地址 /// </summary> public physicaladdress macaddress { get; set; } /// <summary> /// 是否启用dhcp服务 /// </summary> public bool isdhcpenabled { get; set; } /// <summary> /// 描述信息 /// </summary> public string description { get; set; } /// <summary> /// 网络接口类型 /// </summary> /// <returns></returns> public string networkinterfacetype { get; set; } /// <summary> /// 速度 /// </summary> public string speed { get; set; }
(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,子网掩码,网关,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 }, new[] { submask }, null, null); } /// <summary> /// 设置ip网关 /// </summary> public bool setgetwayaddress(string getway) { return setipaddress(null, null, new[] { getway }, null); }

(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 submask, string getway, string dnsmain, 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"); //获取操作设置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", inpar, 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", inpar, null); if (outpar != null) str = outpar["returnvalue"].tostring(); return (str == "0" || str == "1"); } return false; }
