System.Net.IPAddress[] ipAddrs = System.Net.Dns.GetHostAddresses(System.Net.Dns.GetHostName());

                    if (ipAddrs != null && ipAddrs.Length > 0)

                    {

                        //m_JobRunIp = ipAddrs[0].ToString();

                        if (ipAddrs[0].IsIPv6LinkLocal)

                        {

                            m_JobRunIp = ipAddrs[1].ToString();

                        }

                        else

                        {

                            m_JobRunIp = ipAddrs[0].ToString();

                        }

                    }

                    else

                    {

                        m_JobRunIp = System.Net.Dns.GetHostName();

                    }

得到的ipAddrs 数组，如果本机未安装IPV6协议，用 ipAddrs[0]获取本机IP，如果安装， ipAddrs[0]为IP6的IP， ipAddrs[1]为IP4的地址。
