Question

我正在尝试通过WEB API向TFS“ONLINE”提交workItem。它在我的本地机器上工作正常，但是当我将它上传到共享主机服务器时，它无法正常工作。

发生了错误。错误HRESULT E_FAIL已从调用COM组件返回。 System.Runtime.InteropServices.COMException Microsoft.TeamFoundation.WorkItemTracking.Client.DataStore.Datastore.UpdateMetadata（Object rowset，String dbstamp）at at Microsoft.TeamFoundation.WorkItemTracking.Client.DataStore.DataStoreNative.UpdateMetadata（IntPtr handle，Object rowset，String dbstamp，UInt32＆amp; changes）at at Microsoft Microsoft.TeamFoundation上的Microsoft.TeamFoundation.WorkItemTracking.ClientFore.WorkItemTracking.WorkItemStore.InitializeInternal（）中的Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore.RefreshCacheInternal（BackendCallData＆amp; data）中的Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore.EndBackendCall（BackendCallData数据） Microsoft.TeamFoundation.Client.TfsConnection.CreateServiceInstance（程序集程序集）中的Microsoft.TeamFoundation.Client.TfsTeamProjectCollection.InitializeTeamFoundationObject（String fullName，Object instance）的.WorkItemTracking.Client.WorkItemStore.Microsoft.TeamFoundation.Client.ITfsTeamProjectCollectionObject.Initialize（TfsTeamProjectCollection teamProjectCollection），String fullNam e）位于Microsoft.TeamFoundation.Clits.TfsConnection.GetService的Microsoft.TeamFoundation.Client.TfsTeamProjectCollection.GetServiceInstance（类型serviceType，Object serviceInstance）中的Microsoft.TeamFoundation.Client.TfsConnection.GetServiceInstance（类型serviceType，Object serviceInstance）（类型serviceType）位于e：\ Industry \ InsightSoft \ FeedBack \ FeedBackService \ FeedBackService \ Models \ TFSManager.cs：第249行的FeedBackService.Models.TFSManager.AddWorkItem（字符串标题，字符串描述，字符串imagePath）中的Microsoft.TeamFoundation.Client.TfsConnection.GetServiceT位于e：\ Industry \ InsightSoft \ FeedBack \ FeedBackService \ FeedBackService \ Controllers \ ValuesController.cs中的FeedBackService.Controllers.ValuesController.Get（）：位于System.Web.Http的lambda_method（Closure，Object，Object []）的第28行。 Systems.Web.Http.Controllers.ReflectedHttpActionDescriptor中的Controllers.ReflectedHttpActionDescriptor.ActionExecutor。＆lt;＆gt; c_ DisplayClass13.b _c（Object instance，Object [] methodParameters）。在System.Threading.Tasks.TaskHelpers的System.Web.Http.Controllers.ReflectedHttpActionDescriptor。＆lt;＆gt; c_ DisplayClass5.b _4（）的ActionExecutor.Execute（Object instance，Object [] arguments）。 RunSynchronously [TResult]（Func`1 func，CancellationToken cancellationToken）

我的代码：

public void AddWorkItem(string title,string description,string imagePath)
        {
            string _myUri = "https://testredrock.visualstudio.com/DefaultCollection";

            NetworkCredential netCred = new NetworkCredential(userName, password);
            BasicAuthCredential basicCred = new BasicAuthCredential(netCred);

            TfsClientCredentials credential = new TfsClientCredentials(basicCred);
            credential.AllowInteractive = false;

            string TFSServerPath = "https://testredrock.visualstudio.com/DefaultCollection";



            using (TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(new Uri(TFSServerPath), credential))
            {
                CatalogNode catalogNode = tfs.CatalogNode;

                ReadOnlyCollection<CatalogNode> tpNodes = catalogNode.QueryChildren(

                                new Guid[] { CatalogResourceTypes.TeamProject },

                                false, CatalogQueryOptions.None);

                WorkItemStore workItemStore = tfs.GetService<WorkItemStore>();
                Project teamProject = workItemStore.Projects[project];
                WorkItemType workItemType = teamProject.WorkItemTypes[workitemType];

                // Create the work item. 
                WorkItem userStory = new WorkItem(workItemType)
                {
                    // The title is the only required field that does not have a default value. 
                    // You must set it, or you cannot save the work item. 
                    Title = title,
                    Description = "",



                };

                userStory.Fields["Repro Steps"].Value = description;

                // Save the new user story. 
                userStory.Save();

            }

        }

Answer 1

我有同样的错误，虽然我正在研究内部TFS。清除以下文件：

C：\ ProgramData \ Microsoft Team Foundation \ 4.0 \ Cache

我连接到TFS的地方解决了我的问题。

Microsoft.TeamFoundation.WorkItemTracking.Client中的InteropServices.COMException
