Question

我有这个：

private void button1_Click(object sender, EventArgs e)
{

    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://10.123.9.66:80/solr_3.6/wiewaswie_live/select/?qt=edismax_nosyn_a2aperson&q=(huibert faro)&fq={!tag%3Dalldoctypes}doc_type:1&facet.query={!ex%3Dalldoctypes}doc_type:3 AND (b_public:1 OR fk_account:(10847871))&facet.query={!ex%3Dalldoctypes}doc_type:2 AND (b_public:1 OR fk_account:(10847871))&spellcheck=true&spellcheck.count=-3&start=10&sort=name_last asc, score desc&omitHeader=true");

    System.Diagnostics.Stopwatch timer = new Stopwatch();
    timer.Start();

    TimeSpan timeTaken = timer.Elapsed;

    try
    {
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        timer.Stop();
    }
    catch (Exception exception)
    {
        MessageBox.Show(exception.Message);
    }

    try
    {
        using (StreamReader sr = new StreamReader("testSolar.txt"))
        {
            String line = sr.ReadToEnd();
            txtReadFile.Text = timeTaken.ToString();
        }
    }
    catch (Exception exception)
    {
        Console.WriteLine("The file could not be read:");
        Console.WriteLine(exception.Message);
    }
}

但是：HttpWebRequest request = (HttpWebRequest)WebRequest.Create现在是硬编码的。但我有一个包含许多请求的文本文件，如下所示：

所以从每个http我想看到文本框中的响应时间（）：txtReadFile.Text = timeTaken.ToString();

谢谢。

首先，您使用StopWatch类错了。你应该启动它，停止它然后获得经过的时间。

接下来，如果您尝试读取该文件并使用该文件中的网址，则需要先读取文件，然后尝试连接到网址。

以下是我认为你想要的，作为一个控制台应用程序。如果您想在WinForm应用程序中使用它，您可以轻松使用Dictionary<string, TimeSpan>填充数据网格或列表视图，以获得更友好的查看界面。

//Consider making this configurable
const string sourceFile = @"testSolar.txt";

var requester = new WebClient();
var times = new Dictionary<string, TimeSpan>();
var stopwatch = new System.Diagnostics.Stopwatch();

//Add header so if headers are tracked, it will show it is your application rather than something ambiguous
requester.Headers.Add(HttpRequestHeader.UserAgent, "Response-Tester-Client");

var urlList = new List<string>();

//Loop through the lines in the file to get the urls to hit against
try
{
    stopwatch.Start();
    using (var reader = new StreamReader(sourceFile))
    {

        while (!reader.EndOfStream)
        {
            urlList.Add(reader.ReadLine());
        }
    }
}
catch (Exception e)
{
    Console.WriteLine("An error occured while attempting to access the source file at {0}", sourceFile);
}
finally
{
    //Stop, record and reset the stopwatch
    stopwatch.Stop();
    times.Add("FileReadTime", stopwatch.Elapsed);
    stopwatch.Reset();
}

//Try to connect to each url
var counter = 1;
foreach (var url in urlList)
{
    try
    {
        stopwatch.Start();
        requester.DownloadString(url);
    }
    catch (Exception e)
    {
        Console.WriteLine("An error occured while attempting to connect to {0}", url);
    }
    finally
    {
        stopwatch.Stop();

        //We use the counter for a friendlier url as the current ones are unwieldly
        times.Add("Url " + counter, stopwatch.Elapsed);
        counter++;

        stopwatch.Reset();
    }
}

//Release the resources for the WebClient 
requester.Dispose();

//Write the response times
foreach (var key in times.Keys)
{
    Console.WriteLine("{0}: {1}", key, times[key].TotalSeconds);
}
