TFS 2012 - ISubscriber 插件。如何在执行插件时获取项目名称以及可能包含触发 WorkItem 的查询列表？

Question

所以，我有以下 ISubscriber 代码：

public class Subscriber : ISubscriber
{
    public string Namek
    {
        get { return "Subscriber"; }
    }

    public SubscriberPriority Priority
    {
        get { return SubscriberPriority.Normal; }
    }

    public EventNotificationStatus ProcessEvent    (TeamFoundationRequestContext requestContext, NotificationType     notificationType, object notificationEventArgs, out int statusCode, out string     statusMessage, out     Microsoft.TeamFoundation.Common.ExceptionPropertyCollection properties)
    {
        statusCode = 0;
        properties = null;
        statusMessage = String.Empty;

        try
        {
            if(notificationType == NotificationType.Notification && notificationEventArgs is WorkItemChangedEvent)
            {
               var ev = notificationArgs as WorkItemChangedEvent;
               ...........
            }
        }
    }

    public Type[] SubscribedTypes()
    {
        return new Type[1] = { typeof(WorkItemChangedEvent) };
    }
}

代码有效；这意味着在安装插件并且 TFS 识别它之后，在 ProcessEvent 方法中放置一个断点就可以了。

我的问题是我正在尝试获取项目的名称和属于 WorkItem 的 "Shared" 查询，其更改触发了此运行 Subscriber 插件，但我不能似乎找到了这样的引用（我也不知道它们是否通过此接口提供，因为 WorkItemChangedEvent 上的信息太少了）。

有什么建议吗？

Answer 1

WorkItemChangedEvent ev = notificationEventArgs as WorkItemChangedEvent;

您可以使用 Tfs.Aggregator 代码作为类似任务的参考 reference

您应该按照以下行来解决您的问题：

获取项目工作项在
获取项目"Shared Queries"
获取每个查询结果的"Work Item Ids"
检查哪一个包含当前更改的"Work Item Id"

所以代码应该是这样的：

var tfsCollection = new TfsTeamProjectCollection(new Uri(tfsUri));
var tfsStore = tfsCollection.GetService<WorkItemStore>();
var workItemId = ev.CoreFields.IntegerFields[0].NewValue;
var eventWorkItem = tfsStore.GetWorkItem(workItemId);
var project = eventWorkItem.Project;

var queryHierarchy = project.QueryHierarchy;
var queryFolder = queryHierarchy as QueryFolder;
var queryItem = queryFolder["Shared Queries"];
queryFolder = queryItem as QueryFolder;

//below is the list including the queries which include work item this event is attached
var queriesIncludingWorkItem = new List<QueryDefinition>();

if (queryFolder != null)
{
    foreach (QueryDefinition query in queryFolder)
    {
        var wiCollection = tfsStore.Query(query.QueryText);                            

        foreach (WorkItem workItem in wiCollection)
        {
            if (workItem.Id == eventWorkItem.Id)
            {
                queriesIncludingWorkItem.Add(query);
                break;
            }
        }
    }
}

顺便说一句，阿法克；在将 dll 部署到 "Plugins" 文件夹后，您需要回收 iis 应用程序池，以便有时看到更改。
