Check response time with HTTPWebRequest?

问题:

I'm trying to find the performance of some of my proxies. I tried the Ping class in .net but it does not accept ports. Is there a way to check how long a response took with httpwebrequest?

回答1:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(myUri);
System.Diagnostics.Stopwatch timer = new Stopwatch();

timer.Start();

HttpWebResponse response = (HttpWebResponse)request.GetResponse();
response.Close ();

timer.Stop();

TimeSpan timeTaken = timer.Elapsed;

回答2:

Why not just time it from the client side?

WebRequest request = BuildRequest();
Stopwatch sw = Stopwatch.StartNew();
using (WebResponse response = request.GetResponse())
{
    // Potentially fetch all the data here, in case it's streaming...
}
sw.Stop();
Console.WriteLine("Request took {0}", sw.Elapsed);
