IPHostEntry strIp = Dns.Resolve(Environment.MachineName);报错！

IPHostEntry strIp = Dns.Resolve(Environment.MachineName);报错！！！
Page_load代码中写入如下代码：
String   hostIp;
                        hostIp   =   " ";
                        IPHostEntry   strIp   =   Dns.Resolve(Environment.MachineName);
                      //上面一句报错了。有一个警告。
                        for   (int   i   =   0;   i   <   strIp.AddressList.Length;   i++)
                                hostIp   +=   String.Format( "NetCard[{0}],IP={1}\n ",   i   +   1,   strIp.AddressList[i].ToString());
                        Response.Write(hostIp);

错误内容如下：
警告 1 “System.Net.Dns.Resolve(string)”已过时:“Resolve   is   obsoleted   for   this   type,   please   use   GetHostEntry   instead.   http://go.microsoft.com/fwlink/?linkid=14202” D:\BMSystem\BMMain\IpConfig.aspx.cs 25 38 http://localhost/BMSystem/
