c# - WIQL 查询不包括 "System.AssignedTo"字段

Question

我有这个 WIQL，它的目的是找到分配给工作项的用户。

var wiql = string.Format("SELECT [System.Id], [System.WorkItemType], [System.Title], [System.AssignedTo], [System.State]" +
                           " FROM WorkItems" +
                           " WHERE ([System.TeamProject] = '{0}')" +
                           " AND ([System.WorkItemType] = 'Task' OR [System.WorkItemType] = 'Bug')" + 
                           " ORDER BY [System.Id]", projectName);

我正在执行它......

Wiql wiql = new Wiql() { Query = wiqlQueryString };

  using (var workItemTrackingHttpClient = new WorkItemTrackingHttpClient(VstsAccess.AccessUri, VstsAccess.AccessCredentials))
  {
    var workItemQueryResult = workItemTrackingHttpClient.QueryByWiqlAsync(wiql).Result;

    if (workItemQueryResult != null && workItemQueryResult.WorkItemRelations.Any())
    {
      List<int> sourceIdList = new List<int>();
      foreach (var item in workItemQueryResult.WorkItemRelations)
        sourceIdList.Add(item.Target.Id);

      int[] arr = sourceIdList.ToArray();
      string[] fields = { "System.Id", "System.WorkItemType", "System.AssignedTo", "System.Title", "System.Description", "System.State", "System.IterationPath", "System.TeamProject", "System.ChangedDate", "System.ChangedBy", "System.CreatedDate" };
      return workItemTrackingHttpClient.GetWorkItemsAsync(arr, fields, workItemQueryResult.AsOf).Result;
    }
    else
      return new List<WorkItem>();
  }

但是“AssignedTo”和“Description”字段没有出现在工作项的字典字段集中。为什么会这样，我该如何解决？

查询结果将只包含非空字段，即没有人分配给工作项，该字段根本不会在 Fields 字典中。

您需要对这些字段实现自定义检查，并根据您的逻辑将它们分配给某些东西:

            int[] arr = ids.ToArray();

            string[] fields = new string[] {
                "System.Id", 
                "System.Title",
                "System.State",
                "System.AssignedTo"
            };

            var workItems = await workItemTrackingHttpClient.GetWorkItemsAsync(arr, fields, workItemQueryResult.AsOf);

            List<WorkItemData> list = new List<WorkItemData>();

            foreach (var workItem in workItems)
            {
                var wi = new WorkItemData(workItem.Id.Value);

                wi.Title = workItem.Fields["System.Title"].ToString();
                wi.State = workItem.Fields["System.State"].ToString();
                wi.AssignedTo = workItem.Fields.ContainsKey("System.AssignedTo") ? workItem.Fields["System.AssignedTo"].ToString() : "";

                list.Add(wi);

            }
