获取电脑名和IP地址

 private string  GetHostNameAndIP( bool  isv4Orv6)
        {
            string HostName = Dns.GetHostName();//本机名  
            string IPAddress = "";
            System.Net.IPAddress[] addressList = Dns.GetHostAddresses(HostName);//会返回所有地址，包括IPv4和IPv6   
            foreach (IPAddress ip in addressList)
            {
                if (isv4Orv6)
                {
                    if (ip.AddressFamily == AddressFamily.InterNetwork)
                        IPAddress = ip.ToString();
                   
                }
                else
                {
                    if (ip.AddressFamily == AddressFamily.InterNetworkV6)
                        IPAddress = ip.ToString();
                }
               
            }
            return "{HostNmae:'" + HostName + "',Ip:'" + IPAddress + "'}";
