C# 如何使用.net内核中的httpclient获取异步/等待中的REST Get请求的运行时间

当我使用Task.Wait调用下面的DoRestCall方法时，经过的时间基本上显示为0 OK，显示为3ms。我知道这是因为异步/等待模式。我想知道完成rest通话的实际时间。我想不出一个办法进入HttpClient来解决这个问题

public static async Task DoRestCall()
{
    HttpClient client = new HttpClient();
    HttpResponseMessage response = await client.GetAsync("https://http://myrest.com");
    if (response.IsSuccessStatusCode)
    {
        var sw = new Stopwatch();
        sw.Start();
        var x = await response.Content.ReadAsStringAsync();
        sw.Stop();
        Console.WriteLine($"{x.Length} {sw.ElapsedMilliseconds}");
    }
}

您应该移动秒表以同时包含.GetAsync调用

public static async Task DoRestCall()
{
    HttpClient client = new HttpClient();
    string responseBody = String.Empty;
    var sw = new Stopwatch();
    sw.Start();
    HttpResponseMessage response = await client.GetAsync("https://http://myrest.com");
    if (response.IsSuccessStatusCode)
    {        
        responseBody = await response.Content.ReadAsStringAsync();
    }
    sw.Stop();    
    Console.WriteLine($"{responseBody.Length} {sw.ElapsedMilliseconds}");
}

为什么你只在接到请求后才启动秒表？您正在计时ReadAsString部分。异步不是这里的问题，只是您放置秒表的位置。为什么您只在请求后启动秒表？您正在计时ReadAsString部分。异步不是这里的问题，只是你的秒表的位置。
