Question

我有一个项目，我必须向服务器显示查询时间。正在使用多个秒表：

1）对于webservice响应（TechDoctimer）

2）对于db响应（dbTimer）

3）对于功能性能的总时间（定时器），此定时器是＃34;最大的定时器＆＃34;，所有其他定时器都嵌套在其性能中。

因此，我必须获得2个数字（来自db和techdoc秒表），其总和将小于timer，但我得到这样的结果：

服务器总响应时间：1.351（秒）

TechDoc总响应时间：1.215（秒）

数据库价格总响应时间：0.67（秒）

正如您所见，TechDoc +数据库＆gt; 服务器总响应时间。我不明白如果只有Visual Studio不自行进行线程化，这怎么可能发生。

以下是我的功能代码：

 public static FullModel GetDetailList(string article)
    {
        Stopwatch timer = new Stopwatch();
        timer.Start();
        Stopwatch dbTimer = new Stopwatch();
        Stopwatch TechDoctimer = new Stopwatch();

        var db = new TecAllianceEntities();
        FullModel model = new FullModel();
        model.details = new List<DetailModel>();
        List<string> listOfNo = new List<string>();
        int articleId;

        TechDoctimer.Start();
        List<int> listOfIdsFound = RequestDetailIdByArticle(article);
        TechDoctimer.Stop();


        foreach (var item in listOfIdsFound)
        {
            DetailModel detail = new DetailModel();
            detail.oeNumberList = new List<OENumberModel>();
            detail.documents = new List<DocumentModel>();
            detail.attributeList = new List<AttributeModel>();

            articleId = item;

            TechDoctimer.Start();
            string resultFromRequestDetailById = TecAllianceResponce.RequestDetailByIds(articleId);
            TechDoctimer.Stop();

            var result = TecAllianceResponce.GetSorted(resultFromRequestDetailById);

            for (int i = 0; i < result.Count; i++)
            {
                switch (result[i])
                {

当您将结果保存到字符串时，为什么不直接使用TimeSpan.ToString（）输出？
