尝试从团队城市夏普服务器获取开始日期

这是我的代码，用于获取与TeamCitySharp服务器的Json连接。 本地主机是我的 Json 连接。 现在，我正在尝试获取当我转到本地主机时要显示的开始日期，但它显示为空。 关于如何解决这个问题的任何想法？

 HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:81/Status/AllStatuses");
            var response = request.GetResponse();
            var reader = new StreamReader(response.GetResponseStream());
            var responseString = reader.ReadToEnd();
            var serializer = new JavaScriptSerializer();
            serializer.RegisterConverters((new[] { new DynamicJsonConverter() }));
            dynamic obj = serializer.Deserialize(responseString, typeof(object));
            foreach (var objects in obj)
            {       
                foreach (var project in client.Projects)
                {

                    foreach (var build in project.Builds)
                    {
                        bs.date = project.ProjectStartDate.ToString();        

这是在单独项目中调用 Jsonresult 的另一个控制器上。

public JsonResult AllStatuses() //from the json called in the _client view
    {
        var buildStatuses = new List<BuildStatus>();
        var projects = Client.AllProjects();
        //var projects = storeDB.Projects.Include("Builds").ToList();
        //var buildStatuses = new List<BuildStatus>();

        foreach (var project in projects)
        {
            try 
            {
                var buildConfigs = Client.BuildConfigsByProjectId(project.Id);
                foreach (var buildConfig in buildConfigs)
                {
                    var build = Client.LastBuildByBuildConfigId(buildConfig.Id);
                    var b = new BuildStatus();
                    b.id = buildConfig.Id.ToString();
                    if (b.date != null)
                        b.date = b.date.ToString();
                    if (b.status != null)
                        b.status = build.Status.ToString();
                    buildStatuses.Add(b);
                }
            } catch { }
        }
        //var query = buildStatuses.OrderBy(x => x.status); // Create a sorted list from Error - Unknown               
        return Json(buildStatuses, JsonRequestBehavior.AllowGet);
    }
