tfs - Microsoft.TeamFoundation.WorkItemTracking.Client 中的 InteropServices.COMException

Question

我正在尝试通过 WEB API 将工作项提交到 TFS“在线”。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不工作。

发生了错误。调用 COM 组件返回错误 HRESULT E_FAIL。系统.Runtime.InteropServices.COMException在 Microsoft.TeamFoundation.WorkItemTracking.Client.DataStore.DataStoreNative.UpdateMetadata(IntPtr 句柄、对象行集、字符串 dbstamp、UInt32& 更改)在 Microsoft.TeamFoundation.WorkItemTracking.Client.DataStore.Datastore.UpdateMetadata(对象行集、字符串 dbstamp) .TeamFoundation.WorkItemTracking.Client.WorkItemStore.EndBackendCall(BackendCallData 数据)在 Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore.RefreshCacheInternal(BackendCallData& 数据)在 Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore.InitializeInternal() 在 Microsoft.TeamFoundation。 .Client.WorkItemStore.Microsoft.TeamFoundation.Client.ITfsTeamProjectCollectionObject.Initialize(TfsTeamProjectCollection teamProjectCollection) 在 Microsoft.TeamFoundation.Client.TfsTeamProjectCollection.InitializeTeamFoundationObject(String fullName, Object instance) 在 Microsoft.TeamFoundation assembly,AssemblyConnection.Client.Tfs fullName) 在 Mi Microsoft.TeamFoundation.Client.TfsTeamProjectCollection.GetServiceInstance(Type serviceType, Object serviceInstance) 在 Microsoft.TeamFoundation.Client.TfsConnection.GetService(Type serviceType) TeamFoundation.Client.TfsConnection.GetServiceT 位于 FeedBackService.Models.TFSManager.AddWorkItem(字符串标题、字符串描述、字符串图像路径)，位于 e:\Industry\InsightSoft\FeedBack\FeedBackService\FeedBackService\Models\TFSManager.cs:第 249 行，位于 FeedBackService。 Controllers.ValuesController.Get() 在 e:\Industry\InsightSoft\FeedBack\FeedBackService\FeedBackService\Controllers\ValuesController.cs:line 28 at lambda_method(Closure , Object , Object[] ) 在 System.Web.Http.Controllers.ReflectedHttpActionDescriptor .ActionExecutor.<>c_DisplayClass13.b_c(Object instance, Object[] methodParameters) 在 System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor .Execute(Object instance, Object[] arguments) 在 System.Web.Http.Controllers.ReflectedHttpActionDescriptor.<>c_DisplayClass5.b_4() 在 System.Threading.Tasks.TaskHelpers.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();

            }

        }

虽然我正在处理内部 TFS，但我遇到了同样的错误。清除文件在:

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

我从哪里连接到 TFS 为我解决了这个问题。
