c# 中如何用代码实现ping方法实现丢包率计算

在C#中，可以使用`System.Net.NetworkInformation.Ping`类来发送ICMP Echo Request（即Ping请求）并获取响应，进而估算网络延迟和丢包率。以下是一个简单的示例，展示如何实现基本的Ping操作和丢包率计算：

using System;
using System.Diagnostics;
using System.Net.NetworkInformation;

public class PingCalculator
{
    public static void Main(string[] args)
    {
        string target = "www.example.com"; // 替换成你要测试的目标地址
        int pingCount = 5; // 发送请求的数量
        int successCount = 0;
        bool isSuccess;

        for (int i = 0; i < pingCount; i++)
        {
            Ping pingSender = new Ping();
            try
            {
                // 发送ping请求
                var reply = pingSender.Send(target);

                // 如果成功接收到回复
                if (reply.Status == IPStatus.Success)
                {
                    successCount++;
                    Console.WriteLine($"Ping {i + 1}: Response time in ms: {reply.RoundtripTime}ms");
                }
                else
                {
                    Console.WriteLine($"Ping {i + 1}: Failed with error code: {reply.Status}");
                }

                isSuccess = reply.Status == IPStatus.Success;
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Ping failed: {ex.Message}");
                isSuccess = false;
            }
        }

        double packetLossRate = ((double)(pingCount - successCount)) / pingCount * 100;
        Console.WriteLine($"Average packet loss rate: {packetLossRate}%");
