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;安装插件并且TFS识别它之后的意思是，在ProcessEvent方法中放置一个断点。

我的问题是我正在尝试获取项目的名称和属于WorkItem的“共享”查询，其更改触发了此运行到订阅者插件，但我似乎无法找到此类引用（也不是我是否知道它们是否通过此接口提供，因为WorkItemChangedEvent上的信息非常稀疏。）

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reference

的参考

您应该按照这一行来解决您的问题：

获取项目工作项目
获取＆＃34;共享查询＆＃34;项目
获取＆＃34;工作项目ID＆＃34;每个查询结果
检查哪一个包含当前已更改的＆＃34;工作项ID＆＃34;

所以代码应该是：

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;
            }
        }
    }
}

顺便说一下，afaik;在将dll部署到＆＃34;插件＆＃34;之后，您需要回收iis应用程序池。文件夹，以便有时看到更改。
