I have following Code-1 for pinging to single IP and get the ping results. It is working as expected. Now I want to ping to multiple IP's (just few, not hundred of IP's) at the same time, and get their results.

I have written Code-2 but I don't know how to get the results like roundtrip time and ping status for each ping process. In Code1 I got these from the var reply. But in Code2 I don't know how to fetch them?

Code1*****

private async ValueTask PingMachine(string ipadress, string iptype)
{
    var timesToPing = 4;
    var counter = 1;
    while (counter <= timesToPing)
    {
        var reply = await Pinger(ipadress);
        TagService.log_Win.AppendLine($"Pinged {ipadress} {counter} times time:{reply.RoundtripTime} status: {reply.Status.ToString()}");
        }
        counter  ;
    }
}

private async ValueTask<PingReply>
Pinger(string ipAddress)
{
    var ping = new Ping();
    var reply = await ping.SendPingAsync(ipAddress);
    return reply;
}

Code2*****

public static string[] addresses = { "10.92.114.73", "10.92.114.74", "10.92.114.75" };
private async Task<List<PingReply>> Pinger2()
{
    var tasks = addresses.Select(ip => new Ping().SendPingAsync(ip, 2000));
    var reply = await Task.WhenAll(tasks);

    return reply.ToList();
}

Update2******

var replies = await Pinger2();
        foreach (var r in replies)
            {
            TagService.log_Win.AppendLine(replies.Select(r => r.RoundtripTime).ToString());
            }

private async Task<IEnumerable<PingReply>> Pinger2()
 {
   var tasks = addresses.Select(async ip => await new Ping().SendPingAsync(ip, 2000));
   var replies = await Task.WhenAll(tasks);
   return replies;
 }

CodePudding user response：

You just need to await within the lambda

private async Task<IEnumerable<PingReply>> Pinger2()
{
    var tasks = addresses.Select(async ip => await new Ping().SendPingAsync(ip, 2000));
    var replies = await Task.WhenAll(tasks);
    return replies;
}
