推荐答案

您是要测量第一个请求得到响应所花费的时间，还是要包含样式和外部脚本的下载以及客户端渲染?

Do you want to measure the time it takes for the first request to be answered, or do you want to include the downloading of style and external scripts and clientside rendering?

可以通过使用 WebClient .

WebClient client = new WebClient ();

// Add a user agent header in case the 
// requested URI contains a query.

client.Headers.Add ("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();

Stream data = client.OpenRead (@"your-url-here");
StreamReader reader = new StreamReader (data);
string s = reader.ReadToEnd();

stopwatch.Stop();
Console.WriteLine("Time elapsed: {0}", stopwatch.Elapsed);

data.Close();
reader.Close();

对于后者，请放置 WebBrowser 在您创建用于使用

While for the latter, put a WebBrowser on a form where you create a method for consuming the DocumentCompleted event:

// in your form declarations
Stopwatch _stopwatch = new Stopwatch();
String _url = @"your-url-here";

// in the button-click or whenever you want to start the test
_stopwatch.Start();
this.WebBrowser1.Navigate(_url);

// The DocumentCompled event handler
private void WebBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    if (e.Url == _url)
    {  
        _stopwatch.Stop();
        Console.WriteLine("Time elapsed: {0}", _stopwatch.Elapsed);
    }
}
