C#中实现Ping的简单功能

关于用C#实现Ping的功能网上有很多不同的方法，但是很多代码太复杂了。这里少一点的代码来简单模拟一下这个功能。

效果如下：

 

 

 

 

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net.NetworkInformation;


namespace Bing
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Ping p1 = new Ping(); //只是演示，没有做错误处理 
            PingReply reply = p1.Send(this.textBox1.Text);//阻塞方式 
            displayReply(reply); //显示结果 
        }
        private void displayReply(System.Net.NetworkInformation.PingReply reply) //显示结果 
        {
            StringBuilder sbuilder;
            if (reply.Status == IPStatus.Success)
            {
                sbuilder = new StringBuilder();
                sbuilder.Append(string.Format("Address: {0} ", reply.Address.ToString()));
                sbuilder.Append(string.Format("RoundTrip time: {0} ", reply.RoundtripTime));
                sbuilder.Append(string.Format("Time to live: {0} ", reply.Options.Ttl));
                sbuilder.Append(string.Format("Don't fragment: {0} ", reply.Options.DontFragment));
                sbuilder.Append(string.Format("Buffer size: {0} ", reply.Buffer.Length));
                listBox1.Items.Add(sbuilder.ToString());
            }

        }
    }
}
