我的最终目标是递归地获取一个工作项的父项,直到层次结构中不再有父项。目前,还没有任何递归,我仍然在优化获取父工作项的方式。我想到了一种涉及查询的方法:
public WorkItem GetParentWorkItem(int id)
{
StringBuilder queryString = new StringBuilder("SELECT [System.Id]" +
" FROM WorkItemLinks " +
" WHERE [Source].[System.WorkItemType] = '" + TFS_TIMESHEET_WORK_ITEM_TYPE + "'" +
" AND [Source].[System.TeamProject] = '" + TFS_TIMESHEET_PROJECT_KEY + "'" +
" AND [Source].[System.Id] = " + id
);
Query wiQuery = new Query(GetWorkItemStore, queryString.ToString());
WorkItemLinkInfo[] wiTrees = wiQuery.RunLinkQuery();
WorkItem wi = GetWorkItemStore.GetWorkItem(wiTrees[1].TargetId);
return wi;
}
此方法的问题在于它获取所有链接的工作项,包括前任,后继,子和父。我知道wiTrees[1]
是父工作项,因此我对索引进行了硬编码。
我找到了一种从工作项商店获取“父”WorkItemTypeEnd
对象的方法:
WorkItemLinkTypeEnd linkTypEnd = GetWorkItemStore.WorkItemLinkTypes.LinkTypeEnds["Parent"];
我从哪里开始?

这适用于TFS 2013:
var parent_link = work_item.WorkItemLinks.Cast<WorkItemLink> ().FirstOrDefault (x => x.LinkTypeEnd.Name == "Parent");
WorkItem parent_work_item = null;
if (parent_link != null)
parent_work_item = work_item_store.GetWorkItem (parent_link.TargetId);

找到一个解决方案,如果有父项,则返回父WorkItem,否则返回null。
public WorkItem GetParentWorkItem(int id)
{
StringBuilder queryString = new StringBuilder("SELECT [System.Id]" +
" FROM WorkItemLinks " +
" WHERE [Source].[System.WorkItemType] = '" + TFS_TIMESHEET_WORK_ITEM_TYPE + "'" +
" AND [Source].[System.TeamProject] = '" + TFS_TIMESHEET_PROJECT_KEY + "'" +
" AND [Source].[System.Id] = " + id
);
Query wiQuery = new Query(GetWorkItemStore, queryString.ToString());
WorkItemLinkInfo[] wiTrees = wiQuery.RunLinkQuery();
int parentLinkId = GetWorkItemStore.WorkItemLinkTypes.LinkTypeEnds["Parent"].Id;
foreach (WorkItemLinkInfo linkInfo in wiTrees)
{
// -2 is the LinkTypeId for parent
if (linkInfo.LinkTypeId == parentLinkId)
{
workItem = GetWorkItemStore.GetWorkItem(linkInfo.TargetId);
break;
}
else
{
workItem = null;
}
}
return workItem;
}
