该特定字段返回什么？我想要每秒接收的字节数。我应该依赖这个吗？
我认为你可以这样使用它：
long beginValue = NetworkInterface.GetIPv4Statistics().BytesReceived;
DateTime beginTime = DateTime.Now;
// do something
long endValue = NetworkInterface.GetIPv4Statistics().BytesReceived;
DateTime endTime = DateTime.Now;
long recievedBytes = endValue - beginValue;
double totalSeconds = (endTime - beginTime).TotalSeconds;
var bytesPerSecond = recievedBytes / totalSeconds;
用于定期更新的代码片段
private object _lockObj;
private long bytesPerSecond = 0;
private Timer _refreshTimer = new Timer { Interval = 1000 };
// do in ctor or some init method
_refreshTimer.Tick += _refreshTimer_Tick;
_refreshTimer.Enabled = true;
private void _refreshTimer_Tick(object sender, EventArgs e)
{
ThreadPool.QueueUserItem(callback =>
{
long beginValue = NetworkInterface.GetIPv4Statistics().BytesReceived;
DateTime beginTime = DateTime.Now;
Thread.Sleep(1000);
long endValue = NetworkInterface.GetIPv4Statistics().BytesReceived;
DateTime endTime = DateTime.Now;
long recievedBytes = endValue - beginValue;
double totalSeconds = (endTime - beginTime).TotalSeconds;
lock(_lockObj)
{
bytesPerSecond = recievedBytes / totalSeconds;
}
});
}
您可以将其与一些跟踪结合起来，以记录一段时间内接收到的字节数
