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[], 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 = ; nChild < node.ChildNodes[].ChildNodes.Count; nChild++)
GetIterationDates(node.ChildNodes[].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;
}
