TFS获取具有关系和子项的项

azure-devops visual-studio-2017 tfs c#

Dima Shivrin · 技术社区 · 6 年前

我需要一些微软TFS的帮助。(或VST,如果我错了,请纠正我)

我想得到,对于一个给定的项目,所有的关系和孩子。我能够得到关系,但我不了解子项(例如给定backlog下的所有任务,以及所有相关的任务/bug等)。最后,我想展示一个树(或者一个带有所有关系的graphQL样式的显示)。

这是我课堂上的一部分:

using Microsoft.TeamFoundation.WorkItemTracking.WebApi.Models;
using Microsoft.TeamFoundation.Client;

using Microsoft.VisualStudio.Services.Client;
using Microsoft.VisualStudio.Services.Common;
using Microsoft.VisualStudio.Services.WebApi;

public TfsDataProvider(string tfsInstanceUrl, string tfsCollection)
    {
        TfsInstanceUrl = tfsInstanceUrl.TrimEnd('/');
        TfsCollection = tfsCollection;

        TfsUrlPlusCollection = string.Format("{0}/{1}", tfsInstanceUrl, tfsCollection);

        //tfs nuget packages for API version 3.2:
        creds = new VssCredentials();
        creds.Storage = new VssClientCredentialStorage();

        Uri url = new Uri(TfsUrlPlusCollection); //"http://tfs:8080/tfs/aeronautics-100"

        connection = new VssConnection(url, creds);
        wiClient = connection.GetClient<WorkItemTrackingHttpClient>();

        //tracker = new HashSet<int>();
    }



public List<WorkItem> GetWorkItemsByIds(IEnumerable<int> ids)
{
  var wis = wiClient.GetWorkItemsAsync(ids, null, null, WorkItemExpand.Relations).Result;
  return wis;
}

我的问题是我不明白我怎么能把所有的孩子也弄到手。

目前我想给这个函数发送一个id数组(或者现在是一个id),并递归地获取它的所有子级和关系。看来我只知道关系。

    foreach (WorkItem wi in wis)
    {
        if (wi.Relations != null)
        {
            foreach (WorkItemRelation wir in wi.Relations)
            {
                Console.WriteLine(wir.Rel);
                Console.WriteLine(wir.Url);
            }
        }
    }

例如:

 private static void GetWorkItemsTest()
        {
           //var creds = new VssCredentials();
           // creds.Storage = new VssClientCredentialStorage();
            VssCredentials c = new VssCredentials(new Microsoft.VisualStudio.Services.Common.VssBasicCredential(string.Empty, "{PAT}"));
            Uri url = new Uri("https://starain.visualstudio.com"); 

           var connection = new VssConnection(url, c);
           var wiClient = connection.GetClient<WorkItemTrackingHttpClient>();
            IEnumerable<int> ids = new List<int> { 851, 180 };
            var wis = wiClient.GetWorkItemsAsync(ids, null, null, WorkItemExpand.Relations).Result;
            foreach (WorkItem wi in wis)
            {
                Console.WriteLine(wi.Id);
                GetChildrenWIT(wiClient, wi, 1,new List<int> { wi.Id.Value});
            }
        }
        private static void GetChildrenWIT(WorkItemTrackingHttpClient witClient, WorkItem child, int width,List<int> existingWit)
        { 
            if (child.Relations != null)
            {
                foreach (WorkItemRelation wir in child.Relations)
                {
                    var indent = new string('-', width);
                    int id = int.Parse(wir.Url.Split('/').Last());
                    if(!existingWit.Contains(id))
                    {
                        Console.WriteLine(string.Format("{0}{1}", indent, wir.Rel));
                        var childwit = witClient.GetWorkItemAsync(id, null, null, WorkItemExpand.Relations).Result;
                        existingWit.Add(childwit.Id.Value);
                        Console.WriteLine(string.Format("{0}-{1}", indent, childwit.Id));
                        GetChildrenWIT(witClient, childwit, width+1, existingWit);
                    }         
                }
            }
        }

结果如下:

var item = client.GetWorkItemAsync(c_projectName, id, null, null, WorkItemExpand.Relations).Result;

如果不使用此参数,Relations属性将为null。
