在C#编程中,要获取主机名和主机IP地址,是比较容易的.它提供的Dns类,可以轻松的取得主机名和IP地址.

示例:
string strHostName = Dns.GetHostName(); //得到本机的主机名
IPHostEntry ipEntry = Dns.GetHostByName(strHostName); //取得本机IP
string strAddr = ipEntry.AddressList[0].ToString(); //假设本地主机为单网卡

在这段代码中使用了两个类,一个是Dns类,另一个为IPHostEntry类,二者都存在于命名空间System.Net中.
using System.Net
