C#如何获取局域网ip地址

public static string GetLocalIP()
           {
               try
               { 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)
                       {
                           return IpEntry.AddressList[i].ToString();

                       }
                   }
                   return "";
               }
               catch (Exception ex)
               {
                   return "未知";
               }
       }
