内容部署和迁移API不导入不抛出错误

Question

以下内容 http://blogs.technet.com/b/stefan_gossner/archive/2007/08/30/deep-dive-into-the-sharepoint-content-deployment-and-migration-api-part-4.aspx 提供follwoinf代码，以使用内容部署和迁移API导入和导出项目。

           SPWeb web = site.OpenWeb("/PressReleases");

           SPList list = web.Lists["TargetList"];

           SPImportObjectCollection rootObjects = args.RootObjects;

           foreach (SPImportObject io in rootObjects)

           {

               io.TargetParentUrl = list.RootFolder.ServerRelativeUrl;

           }

           web.Dispose();

           site.Dispose();

       }     
   }     
}

好的，太好了。我已经改变了seetings，所以它使用我的列表名称和我的网站url。出口很好.导入不起作用.我正在文档lib上执行代码。不会抛出任何错误，但内容项未更改列表。

可能出了什么问题？即使我在导出后删除原始项目，然后在不更改父列表的情况下进行导入，也不会发生任何事情。

我已经测试了你的代码，发现问题是在导出过程中创建的文件没有在本地磁盘上正确清理。我实现了文件删除逻辑，以确保导出和导入工作正常。注意，我运行了有和没有的导出和导入 FileCompression 两者都工作正常。我在两个图片库上运行了我的测试。

对不起，我没有太多时间来改进你的代码。正确处理SPWeb和SPSite对象。希望你会自己做。

更新后的代码粘贴在下面:

class Program
    {
        static void Main(string[] args)
        {
            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                // implementation details omitted
                SPSite site = new SPSite("http://mylocaldev/");
                SPWeb web = site.OpenWeb("/");
                SPList list = web.Lists["ParentPic"];
                SPListItem listItem = list.Items[0];

                try
                {
                    //delete the old files
                    DirectoryInfo dir = new DirectoryInfo(@"c:\export\CopyListItem");
                    foreach (System.IO.FileInfo file in dir.GetFiles()) file.Delete();                    

                    // export                        
                    SPExportObject exportObject = new SPExportObject();
                    exportObject.Id = listItem.UniqueId;

                    exportObject.Type = SPDeploymentObjectType.ListItem;
                    SPExportSettings exportSettings = new SPExportSettings();
                    exportSettings.ExportObjects.Add(exportObject);
                    exportSettings.FileLocation = @"c:\export\CopyListItem";

                    exportSettings.FileCompression = false;

                    //exportSettings.BaseFileName = "exportfile.cmp";

                    exportSettings.SiteUrl = "http://mylocaldev/";

                    SPExport export = new SPExport(exportSettings);

                    export.Run();

                }
                catch (Exception ex)
                {

                }
                finally { web.Dispose();}


                // import

                SPImportSettings importSettings = new SPImportSettings();

                importSettings.SiteUrl = "http://mylocaldev/";

                importSettings.FileLocation = @"c:\export\CopyListItem";

                importSettings.FileCompression = false;

                //importSettings.BaseFileName = "exportfile.cmp";

                importSettings.RetainObjectIdentity = false;

                SPImport import = new SPImport(importSettings);

                EventHandler<SPDeploymentEventArgs> startedEventHandler = new EventHandler<SPDeploymentEventArgs>(OnStarted);

                import.Started += startedEventHandler;

                import.Run();

                // cleanup

                site.Dispose();

            });

        }

        // event handler to assign a new parent to the orphaned image in the package

        static void OnStarted(object sender, SPDeploymentEventArgs args)
        {

            SPSite site = new SPSite("http://mylocaldev/");

            SPWeb web = site.OpenWeb("/");

            SPList list = web.Lists["ChildPic"];

            SPImportObjectCollection rootObjects = args.RootObjects;

            foreach (SPImportObject io in rootObjects)
            {

                io.TargetParentUrl = list.RootFolder.ServerRelativeUrl;

            }

            web.Dispose();

            site.Dispose();

        }
    }

Answer 2

幸运的是，在几天之前，我正在研究类似的任务。

我尝试过您的代码。几乎是它的工作。

但我同意@falak，你应该用正确的尝试/ catch和sharepoint标准编码模式编写代码。

这里，我发现一旦你的代码应该完全运行，第二次你应该得到错误，因为你没有清理你的文件位置文件夹哪一个：“ c：\ export \Copylistitem “。

这可能对您有所帮助。
