c# 怎么对网络信息进行相关设置(ip,dns,网关等)

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)); }
}

public bool EnableDhcp()
{
 var wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");
 var moc = wmi.GetInstances();
 foreach (var o in moc)

   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;
}

 switch (IpAddresses.Count)
 {
  case 3:
   return IpAddresses[2];
  case 2:
   return IpAddresses[1];
 }
 return IpAddresses[0];

  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
