数组C＃WPF

Question

我正在使用C＃WPF开发一个新程序，其中一部分包括平均十PingReply.RoundTripTime并将其除以2以找到单向行程时间。我将所有PingReply个实例放在一个数组arrayReply中，现在想要执行上述操作。我尝试了很多东西，但这就是我现在所拥有的：

//New integer replyCount for counting ping replies
int replyCount = 0;
long Atime = 0;
long time = 0;

//for each PingReply instance in arrayReply
foreach (PingReply r in arrayReply)
{
    //set long integer (64-bit) Atime (time of ping) to the previous value of Atime
    //plus half of the next RoundTripTime divided by 2 (for approx one-way distance)
    long oneWayTime = r.RoundtripTime / 2;

    long x = Atime + oneWayTime;

    //add one to replyCount
    replyCount++;

    //Divide Atime by number of replies
    time = x / replyCount;
}

pingAverage.Text = time.ToString();

但是，每次都会产生0。我该如何解决这个问题？

Answer 1

使用LINQ进行平均：

var time = arrayReply.Average(pr => pr.RoundtripTime) / 2;
