RegisteredTfsConnections.GetProjectCollection我得到nullexception

我有一些来自MS的示例代码连接到TFS并返回没有问题的集合和项目。 但是当我使用不同的代码连接来获取版本控制数据时，我得到一个空的exception错误。

using System; using System.Collections.ObjectModel; using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.Framework.Common; using Microsoft.TeamFoundation.Framework.Client; using Microsoft.TeamFoundation.VersionControl.Client; namespace TfsApplication { class Program { static void Main(String[] args) { /* Working Code Base */ // Connect to Team Foundation Server // Server is the name of the server that is running the application tier for Team Foundation. // Port is the port that Team Foundation uses. The default port is 8080. // VDir is the virtual path to the Team Foundation application. The default path is tfs. Uri tfsUri = (args.Length < 1) ? new Uri("http://mydomain.com:8080/tfs") : new Uri(args[0]); TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(tfsUri); // Get the catalog of team project collections ReadOnlyCollection collectionNodes = configurationServer.CatalogNode.QueryChildren( new[] { CatalogResourceTypes.ProjectCollection }, false, CatalogQueryOptions.None); // List the team project collections foreach (CatalogNode collectionNode in collectionNodes) { // Use the InstanceId property to get the team project collection Guid collectionId = new Guid(collectionNode.Resource.Properties["InstanceId"]); TfsTeamProjectCollection teamProjectCollection = configurationServer.GetTeamProjectCollection(collectionId); // Print the name of the team project collection Console.WriteLine("Collection: " + teamProjectCollection.Name); // Get a catalog of team projects for the collection ReadOnlyCollection projectNodes = collectionNode.QueryChildren( new[] {CatalogResourceTypes.TeamProject}, false, CatalogQueryOptions.None); // List the team projects in the collection foreach (CatalogNode projectNode in projectNodes) { Console.WriteLine(" Team Project: " + projectNode.Resource.DisplayName); } } /*Non-Working Code Base*/ var server = RegisteredTfsConnections.GetProjectCollection(tfsUri); var projects = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(server); var versionControl = (VersionControlServer)projects.GetService(typeof(VersionControlServer)); //var newestDate = DateTime.MinValue; //Item newestItem = null; var items = versionControl.GetItems("$/MyProject/DEV/*.*"); Console.ReadKey(); foreach (var item in items.Items) { Console.WriteLine(item.ServerItem); } } } } 

我修改了上面的代码，尝试在另一个stackoverflow [文章] [1]中找到的另一个方法。

[1]： RegisteredTfsConnections.GetProjectCollection在测试服务器上返回null，但在dev服务器上没有返回但是我得到TF31002：无法连接到此Team Foundation Server错误。 不知道该解决什么问题。

  Uri tfsUri2 = new Uri("http://mydomain.com:8080/tfs"); var projects = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(tfsUri2); var versionControl = (VersionControlServer)projects.GetService(typeof(VersionControlServer));

您希望连接到Team Project Collection以获取版本控制客户端。 最简单的方法是指定集合的​​URL。 例如，如果要连接到默认的Team Project Collection（名为DefaultCollection ）：

 var tfs = new TfsTeamProjectCollection(new Uri("http://example.com:8080/tfs/DefaultCollection")); var versionControl = (VersionControlServer)tfs.GetService(typeof(VersionControlServer));
