问题描述

我们正在使用SharePoint2016.将项目导入SharePoint库时，我们会遇到错误消息.我们要导出库的最新主版本，然后导入到目标系统.导入时，我们会收到"Save Conflict"(保存冲突)信息，错误消息，如以下代码片段所示.

We are using SharePoint 2016. We are experiencing error messages when importing items to SharePoint libraries. We want to export most recent major version of the library and import to the destination system. While importing we are getting "Save Conflict" error messages as in the following snippet.

System.Runtime.InteropServices.COMException: <nativehr>0x8107054a</nativehr><nativestack></nativestack>Save Conflict  Your changes conflict with those made concurrently by another user. If you want your changes to be applied, click Back in your Web browser, refresh the page, and resubmit your changes., StackTrace:   
 at Microsoft.SharePoint.Deployment.FileSerializer.CreateOrUpdateFileWithGuid(SPFileStream spstm, SPLoggerObject loggerObject, SPWeb web, Guid fileId, String fileUrl, Int32 authorId, String authorLoginName, Int32 editorId, String editorLoginName, String checkinComment, DateTime timeCreated, DateTime timeLastModified, MetaInfoHandler metaInfo, Int32 length, Int32 iVersion, Boolean isFirstVersion, SPImportSettings settings, Int32 listItemId, String listInternalName, ImportObjectManager objectManager)

下一个代码片段显示了我们用于从源系统导出库的代码.如果我们使用SPIncludeVersions.LastMajor选项，则会发生错误.如果我们在源系统上的库上禁用版本控制，或者我们使用SPIncludeVersions.All 选项，那么我们不会收到错误消息.

The next snippet shows the code we are using to export library from the source system. The error happens, if we use SPIncludeVersions.LastMajor option. If we disable versioning on the library on the source system or we use SPIncludeVersions.All option then we do not get the error message.

private static void DoListExport(string listName, bool excludeBlacklistPages)
        {
            try
            {
                LogInfo("Running List Export");
                using (SPSite sourceSite = new SPSite(sourceHostUrl))
                {
                    using (SPWeb sourceWeb = sourceSite.OpenWeb())
                    {
                        SPExportSettings exportSettings = new SPExportSettings();
                        exportSettings.SiteUrl = sourceSite.Url;
                        
                        exportSettings.ExportMethod = SPExportMethodType.ExportAll;

                        exportSettings.BaseFileName = dataFile;
                        exportSettings.FileLocation = workFolder;
                        exportSettings.LogFilePath = workFolder + "\\" + exportLogFile;
                        exportSettings.IncludeSecurity = SPIncludeSecurity.None;
                        exportSettings.OverwriteExistingDataFile = true;
                        exportSettings.CommandLineVerbose = true;
                        exportSettings.FileCompression = false;
                        exportSettings.FileMaxSize = Int32.MaxValue;
                        exportSettings.IncludeVersions = SPIncludeVersions.LastMajor;
                        exportSettings.ExcludeDependencies = true;

                        foreach (SPWeb web in sourceSite.AllWebs)
                        {
                            SPList list = web.Lists.Cast<SPList>().FirstOrDefault(l => l.Title == listName);                            
                                    
                            if(list != null){
                                LogInfo("Exporting list:" + list.Title);
                                var exportObjectList = new SPExportObject();
                                exportObjectList.Id = list.ID;
                                exportObjectList.Type = SPDeploymentObjectType.List;
                                exportObjectList.IncludeDescendants = SPIncludeDescendants.All;
                                exportSettings.ExportObjects.Add(exportObjectList);
                            }
                                                   
                        }
                        exportSettings.Validate();
                        SPExport export = new SPExport(exportSettings);
                        export.Run();


                        LogInfo("Export completed successfully");
                    }
                }
            }
            catch (Exception ex)
            {
                LogError("Error while exporting - " + ex.Message + "-" + ex.StackTrace);
                throw;
            }
        }

下一个代码片段显示了用于将库导入到目标系统的代码.这是引发错误的代码.请帮助找到原因并消除错误.

The next snippet shows the code used to import the library to the destination system. This is the code that throws an error. Please help with finding the reason and eliminating the error.

private static void Import()
        {
            LogInfo("Running Import");

            using (SPSite destinationSite = new SPSite(destinationHostUrl))
            {
                SPWebApplication webApplication = destinationSite.WebApplication;
                destinationSite.AllowUnsafeUpdates = true;                

                using (SPWeb destinationWeb = destinationSite.OpenWeb())
                {
                    destinationWeb.AllowUnsafeUpdates = true;
                    webApplication.FormDigestSettings.Enabled = false;
                    webApplication.FormDigestSettings.Expires = false;
                    SPImportSettings importSettings = new SPImportSettings(new Uri(destinationHostUrl), workFolder, dataFile);
                    importSettings.IncludeSecurity = SPIncludeSecurity.None;
                    importSettings.RetainObjectIdentity = true;
                    importSettings.CommandLineVerbose = true;
                    importSettings.LogFilePath = workFolder + "\\" + importLogFile;
                    importSettings.WebUrl = destinationWeb.Url;
                    importSettings.SiteUrl = destinationSite.Url;
                    importSettings.FileCompression = false;

                    SPImport import = new SPImport(importSettings);
                    import.Run();
                    destinationWeb.AllowUnsafeUpdates = false;
                    webApplication.FormDigestSettings.Enabled = true;
                    webApplication.FormDigestSettings.Expires = true;
                    destinationWeb.Close();
                    LogInfo("Import Process completed successfully");
                }
                destinationSite.AllowUnsafeUpdates = false;
                destinationSite.Close();
            }
            LogInfo("Import Completed Successfully!");
        }
