.net获取本地ip地址

整理代码，.net获取本地ip地址，代码如下：

 1 string name = Dns.GetHostName();  
 2 IPHostEntry IpEntry = Dns.GetHostEntry(name);
 3 string ip = "";
 4 for (int i = 0; i < IpEntry.AddressList.Length; i++)
 5 {
 6     //从IP地址列表中筛选出IPv4类型的IP地址
 7     //AddressFamily.InterNetwork表示此IP为IPv4,
 8     //AddressFamily.InterNetworkV6表示此地址为IPv6类型
 9     if (IpEntry.AddressList[i].AddressFamily == AddressFamily.InterNetwork)
10     {
11          ip= IpEntry.AddressList[i].ToString();
12     }
13 }
