1、网络编程实验实验一IPAddress类、Dns类、IPHostEntry类和IPEndPoint类的使用方法。1.界面（各控件名称如图所示）textBox1listBox1Button1Button22、代码如下：usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Fo

3、ns.GetHostEntry(name);listBox1.Items.Add("本机所有的IP地址：");foreach(IPAddressipinme.AddressList){listBox1.Items.Add(ip);}IPAddresslocalip=IPAddress.Parse("127.0.0.1");IPEndPointiep=newIPEndPoint(localip,80);listBox1.Items.Add("theIPEndPointis："+iep.ToString());listBox1.Items.

4、Add("theAddressis："+iep.Address);listBox1.Items.Add("theAddressFamilyis："+iep.AddressFamily);listBox1.Items.Add("themaxportnumberis："+IPEndPoint.MaxPort);listBox1.Items.Add("theminportnumberis："+IPEndPoint.MinPort);}privatevoidbutton2_Click(objectsender,EventArgse){listB
