TFS二次开发的数据统计以PBI、Bug、Sprint等为例（一）

在TFS二次开发中，我们可能会根据某一些情况对各个项目的PBI、BUG等工作项进行统计。在本文中将大略讲解如果进行这些数据统计。

　　一：连接TFS服务器，并且得到之后需要使用到的类方法。

   /// <summary>
        /// tfs的
        /// </summary>
        private TfsTeamProjectCollection server;
        private WorkItemStore workstore;
        private TeamSettingsConfigurationService configSvc;
        private TfsTeamService teamService;
        public String TfsUri { get; set; }

        /// <summary>
        /// 初始化TFSServer
        /// </summary>
        /// <param name="model"></param>
        public TFSServerDto(string tfsUri)
        {
            this.TfsUri = tfsUri;
            Uri uri = new Uri(TfsUri);
            server = new TfsTeamProjectCollection(uri);
            workstore = (WorkItemStore)server.GetService(typeof(WorkItemStore));
            configSvc = server.GetService<TeamSettingsConfigurationService>();
            teamService = server.GetService<TfsTeamService>();

        }

　　二：获取到本TFS Server 指定团队的所有项目

        /// <summary>
        /// 获取项目集合
        /// </summary>
        /// <returns></returns>
        public ProjectCollection GetProjectList()
        {
            return workstore.Projects;
        }
        public Project GetProject(int projectId)
        {
            return workstore.Projects.GetById(projectId);
        }

　　三：根据工作项类型获取工作项集合

        /// <summary>
        /// 获取工作项统计
        /// </summary>
        /// <param name="workitemtype">工作项类型：Bug,Impediment,Product Backlog Item,Task,Task Case</param>
        /// <returns></returns>
        public WorkItemCollection GetWorkItemCollection(string workitemtype, string projectName)
        {
            WorkItemCollection queryResults = GetWorkItemCollection(workitemtype,projectName, string.Empty);
            return queryResults;
        }

        /// <summary>
        /// 获取工作项统计
        /// </summary>
        /// <param name="workitemtype">工作项类型：Bug,Impediment,Product Backlog Item,Task,Task Case等</param>
        /// <param name="condition">查询条件:针对Bug类型的       State=‘New,Approved,Committed,Done,Removed'
        ///                                  针对Impediment类型的State='Open'
        ///                                  针对Product Backlog Item类型的State='New'
        ///                                  针对Task类型的      State='To Do'
        ///                                  针对Task Case类型的 State='Design'
        /// <returns></returns>
        public WorkItemCollection GetWorkItemCollection(string workitemtype,string projectName,string condition)
        {
            string sql = @"Select  [Title] From WorkItems Where [Work Item Type] = '{0}' and [System.TeamProject] = '{1}' ";
            if (!string.IsNullOrEmpty(condition))
            {
                sql +=" and "+ condition;
            }
            sql = string.Format(sql, workitemtype, projectName);
            WorkItemCollection queryResults = workstore.Query(sql);
            return queryResults;
        }

　　四：获取Sprint信息和开始、结束时间

       /// <summary>
        /// 获取项目的Sprint信息
        /// </summary>
        /// <param name="projectUri">project的Uri信息</param>
        /// <returns></returns>
        public TeamSettings GetSprintInfo(String projectUri)
        {
            TeamFoundationTeam team = teamService.QueryTeams(projectUri).First();
            IList<Guid> teamGuids = new List<Guid>() { team.Identity.TeamFoundationId };
            TeamConfiguration config = configSvc.GetTeamConfigurations(teamGuids).FirstOrDefault();
            var members = team.GetMembers(server, MembershipQuery.Direct);
            var users = members.Where(m => !m.IsContainer);

            return config.TeamSettings;
        }
        /// <summary>
        /// 获取项目Sprint的关键信息如开始时间和结束时间
        /// </summary>
        /// <param name="projectUri"></param>
        /// <returns></returns>
        public IEnumerable<ScheduleInfo> GetIterationDates(string projectUri)
        {
            var css = server.GetService<ICommonStructureService4>();
            NodeInfo[] structures = css.ListStructures(projectUri);
            NodeInfo iterations = structures.FirstOrDefault(n => n.StructureType.Equals("ProjectLifecycle"));
            List<ScheduleInfo> schedule = null;
            if (iterations != null) {
                string projectName = css.GetProject(projectUri).Name;
                XmlElement iterationsTree = css.GetNodesXml(new[] { iterations.Uri }, true);
                GetIterationDates(iterationsTree.ChildNodes[0], projectName, ref schedule);
            }
            return schedule;
        }
        /// <summary>
        /// 通过解析XML得到Sprint的开始和结束时间
        /// </summary>
        /// <param name="node"></param>
        /// <param name="projectName"></param>
        /// <param name="schedule"></param>
        private  void GetIterationDates(XmlNode node, string projectName, ref List<ScheduleInfo> schedule)
        {     if (schedule == null)
            schedule = new List<ScheduleInfo>();
            if (node != null)
            {
                string iterationPath = node.Attributes["Path"].Value;
                if (!string.IsNullOrEmpty(iterationPath))
                {
                    // Attempt to read the start and end dates if they exist.
                    string strStartDate = (node.Attributes["StartDate"] != null) ? node.Attributes["StartDate"].Value : null;
                    string strEndDate = (node.Attributes["FinishDate"] != null) ? node.Attributes["FinishDate"].Value : null;
                    DateTime? startDate = null, endDate = null;
                    if (!string.IsNullOrEmpty(strStartDate) && !string.IsNullOrEmpty(strEndDate))
                    {
                        bool datesValid = true;
                        // Both dates should be valid.
                        startDate = DateTime.Parse(strStartDate);
                        endDate = DateTime.Parse(strEndDate);
                        schedule.Add(new ScheduleInfo
                        {
                            Path = iterationPath.Replace(string.Concat("\\", projectName, "\\Iteration"), projectName),
                            StartDate = startDate,
                            EndDate = endDate
                        });
                    }
                }
                // Visit any child nodes (sub-iterations).
                if (node.FirstChild != null)
                {
                    // The first child node is the <Children> tag, which we'll skip.
                    for (int nChild = 0; nChild < node.ChildNodes[0].ChildNodes.Count; nChild++)
                        GetIterationDates(node.ChildNodes[0].ChildNodes[nChild], projectName, ref schedule);
                }
            }
        }

　　五：获取团队成员名单

        /// <summary>
        /// 获取项目的Sprint信息
        /// </summary>
        /// <param name="projectUri">project的Uri信息</param>
        /// <returns></returns>
        public IEnumerable<TeamFoundationIdentity> GetMemberInfo(String projectUri)
        {
            TeamFoundationTeam team = teamService.QueryTeams(projectUri).First();
            var members = team.GetMembers(server, MembershipQuery.Direct);
            var users = members.Where(m => !m.IsContainer);
            return users;
        }
