Question

我正在使用TFS API将TFS 2010团队项目迁移到TFS 2015。我在尝试拨打VersionControlServer.GetLatestChangesetId()和VersionControlServer.QueryHistory(...)时遇到了问题。

我正在使用2015年的nuget Team Foundation软件包来提供dll。

我得到的例外是：

'VersionControlServer.GetLatestChangesetId()' threw an exception of type 'System.Xml.XmlException'
    Data: {System.Collections.ListDictionaryInternal}
    HResult: -2146232000
    HelpLink: null
    InnerException: null
    LineNumber: 0
    LinePosition: 0
    Message: "Unexpected end of file."
    Source: "System.Runtime.Serialization"
    SourceUri: null
    StackTrace: "   at System.Xml.EncodingStreamWrapper.ReadBOMEncoding(Boolean notOutOfBand)\r\n   at System.Xml.EncodingStreamWrapper..ctor(Stream stream, Encoding encoding)\r\n   at System.Xml.XmlUTF8TextReader.SetInput(Stream stream, Encoding encoding, XmlDictionaryReaderQuotas quotas, OnXmlDictionaryReaderClose onClose)\r\n   at Microsoft.TeamFoundation.Client.Channels.TfsSoapMessageEncoder.ReadMessage(Stream stream)\r\n   at Microsoft.TeamFoundation.Client.Channels.TfsHttpWebRequest.ReadMessage(HttpWebResponse webResponse, WebException webException, Stream responseStream, Boolean& closeResponse)\r\n   at Microsoft.TeamFoundation.Client.Channels.TfsHttpWebRequest.ReadResponse(HttpWebResponse webResponse, WebException webException)\r\n   at Microsoft.TeamFoundation.Client.Channels.TfsHttpWebRequest.IsAuthenticationChallenge(TfsMessage requestMessage, HttpWebResponse webResponse, WebException webException, TfsMessage& responseMessage)\r\n   at Microsoft.TeamFoundation.Client.Channels.TfsHttpWebRequest.SendR

    TargetSite: {SupportedEncoding ReadBOMEncoding(Boolean)}

QueryHistory和GetLatestChangesetId的异常基本相同。从堆栈跟踪看，TFS可能在2010年到2015年之间处理不同的编码。

我正在寻找一种解决方案，允许我通过API查询旧版TFS 2010和新的TFS 2015.

Answer 1

我可以使用API从TFS2010和TFS2015查询，以下是我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.VersionControl.Client;

namespace TFSAPI
{
    class Program
    {
        static void Main(string[] args)
        {
            string project = "http://xxxxx:8080/tfs/DefaultCollection";
            NetworkCredential nc = new NetworkCredential("username","pwd");
            TfsTeamProjectCollection tpc = new TfsTeamProjectCollection(new Uri(project), nc);
            tpc.Authenticate();
            VersionControlServer vcs = tpc.GetService<VersionControlServer>();
            int cid = vcs.GetLatestChangesetId();
            string p = "$/ProjectName";
            var h = vcs.QueryHistory(p,RecursionType.Full,5);
            Console.WriteLine("Following are the latest 5 changeset in " + p +":");
            foreach (Changeset item in h)
            {
                Console.WriteLine("{0} {1}", item.ChangesetId, item.Comment);
            }
            Console.WriteLine("The latest changeset ID is:" + cid);
            Console.ReadLine();
        }
    }
}

假设您使用相应的VS版本来使用TFS。对于Visual Studio的每个主要版本，我们可能需要重新构建我们的TFS版本控制项目，以定位客户端对象模型的新版本。您想要的是构建引用TFS客户端dll并支持混合环境的项目。您可以查看http://blogs.msdn.com/b/phkelley/archive/2013/08/12/checkin-policy-multitargeting.aspx以了解可能适合您的方法。

希望这会对你有所帮助。

是否可以将TFS 2015 api用于TFS 2010中的QueryHistory更改集？
