获取IPV4地址

//获取IPV4地址

string HostName = Dns.GetHostName(); //得到主机名
IPHostEntry IpEntry = Dns.GetHostEntry(HostName);
for (int i = 0; i < IpEntry.AddressList.Length; i++)
{
  //从IP地址列表中筛选出IPv4类型的IP地址
  //AddressFamily.InterNetwork表示此IP为IPv4,
  //AddressFamily.InterNetworkV6表示此地址为IPv6类型
  if (IpEntry.AddressList[i].AddressFamily == AddressFamily.InterNetwork)
  {
     IpEntry.AddressList[i].ToString();
  }
}
