.net获取本地ip地址

整理代码，.net获取本地ip地址，代码如下：

 string name = Dns.GetHostName();
 IPHostEntry IpEntry = Dns.GetHostEntry(name);
 string ip = "";
 for (int i = ; 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)
     {
          ip= IpEntry.AddressList[i].ToString();
     }
 }
