SharePoint 2010:在列表之间复制文档

找到了解决方案:

            SPDocumentLibrary fromList = (SPDocumentLibrary)SPContext.Current.Site.RootWeb.Lists.TryGetList(ListNames.DocmentListName);

            SPWeb currentWeb = SPContext.Current.Web;

            SPDocumentLibrary toList = (SPDocumentLibrary)currentWeb.Lists.TryGetList(ListNames.DocmentListName);

            SPFileCollection collection = fromList.RootFolder.Files;

            foreach (SPFile item in collection)
            {
                toList.RootFolder.Files.Add(item.Url, item.OpenBinary());
            }
