Detailed timing info from HttpWebRequest

Question

I'm trying to extract detailed timing info, much like the Timing tab in Chrome, from a HTTP request made through HttpWebRequest in .NET:

Anyone know if this is possible? I cannot find any other documentation, than wrapping the entire request in a Stopwatch. But I really want the details, like how long it takes to resolve from DNS, how long it takes to request, content download etc.

Answer 1

For future reference, I'm answering my own question. While the proposed answer with the logger might work, I've found a better (IMO) and much simpler approach:

var waiting = new Stopwatch();
var contentDownload = new Stopwatch();
waiting.Start();
using (var webResponse = (HttpWebResponse)webRequest.GetResponse())
{
    waiting.Stop();
    contentDownload.Start();
    using (var reader = new StreamReader(webResponse.GetResponseStream()))
    {
        var body = reader.ReadToEnd();
        contentDownload.Stop();
    }
}

It's as simple as that really. Calling GetResponse corresponds Chrome's Waiting and GetResponseStream+ReadToEnd corresponds Content Download.

In this example I'm making a GET (body-less) request. Being able to time Request Sent would make sense, but not really achievable using this approach.
