Question

用C#写一个类似cmd的控制台程序，实现ping的功能！！！（求完整程序源代码！）

Answer 1

using System;
using System.Net;
using System.Net.NetworkInformation;
class Program
{
    static void Main(string[] args)
    {
        int count = 4;
        IPAddress addr = IPAddress.Parse("220.181.111.86");
        Ping ping = new Ping();
        long timeSum = 0;
        int succCount = 0;
        //发送
        Console.WriteLine("正在ping {0}", addr);
        for (int i = 0; i < count; ++i)
        {
            PingReply pr = ping.Send(addr);
            if (pr.Status == IPStatus.TimedOut)
                Console.WriteLine("超时");
            else if (pr.Status == IPStatus.Success)
            {
                Console.WriteLine("延时：{0}毫秒", pr.RoundtripTime);
                ++succCount;
                timeSum += pr.RoundtripTime;
            }
        }
        if (timeSum != 0)
            Console.WriteLine("平均延时{0}毫秒，丢包率{1}%", 1.0 * timeSum / succCount, (count - succCount) * 100.0 / count);
        else
            Console.WriteLine("丢包率100%");
        return;
    }
}

using System.Diagnostics;

static void Main(string[] args)
{
string ip = "202.108.22.103";
string strRst = CmdPing(ip);
Console.WriteLine(strRst);
Console.ReadLine();
}
private static string CmdPing(string strIp)
{
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
string pingrst;
p.Start();
p.StandardInput.WriteLine("ping -n 1 " + strIp);
p.StandardInput.WriteLine("exit");
string strRst = p.StandardOutput.ReadToEnd();
if (strRst.IndexOf("(0% loss)") != -1)
pingrst = "连接";
else if (strRst.IndexOf("Destination host unreachable.") != -1)
pingrst = "无法到达目的主机";
else if (strRst.IndexOf("Request timed out.") != -1)
pingrst = "超时";
else if (strRst.IndexOf("Unknown host") != -1)
pingrst = "无法解析主机";
else
pingrst = strRst;
p.Close();
return pingrst;
}
}

追问

这个不能用啊？

追答

你有没有加引用，还有你看代码 你把需要输入IP的地方
替换一下stringip ="202.108.22.103";
换成string ip= console.readline();
就行了
