如何以编程方式还原儿童Sitecore项目？

Question

I can currently delete items by calling item.DeleteChildren() and if there is an error I would like to restore those items by having the original item list var originalItems = item.GetChildren(); but how can I restore them so that the values that were inside those template fields also remain?

I tried executing the following but all that does is recreate the template without the field values.

foreach (Item backupItem in backupItems)
{
    item.Add(backupItem.Name, backupItem.Template);
}

You can archive them instead of deleting them and the restore them if need be.

Code via John West

Sitecore.Data.Items.Item item = Sitecore.Context.Item;
Sitecore.Diagnostics.Assert.IsNotNull(item, "item");
Sitecore.Data.Archiving.Archive archive = 
Sitecore.Data.Archiving.ArchiveManager.GetArchive("archive", item.Database);

foreach (Sitecore.Data.Items.Item child in item.Children)
{
  if (archive != null)
  {
    // archive the item
    archive.ArchiveItem(child);
    // to archive an individual version instead: archive.ArchiveVersion(child);
  }
  else
  {
    // recycle the item
    // no need to check settings and existence of archive
    item.Recycle();
    // to bypass the recycle bin: item.Delete();
    // to recycle an individual version: item.RecycleVersion();
    // to bypass the recycle bin for a version: item.Versions.RemoveVersion();
  }
}

To restore, use the same Archive class.

using (new SecurityDisabler())
{
    DateTime archiveDate = new DateTime(2015, 9, 8);
    string pathPrefix = "/sitecore/media library";

    // get the recyclebin for the master database
    Sitecore.Data.Archiving.Archive archive = Sitecore.Data.Database.GetDatabase("master").Archives["recyclebin"];

    // get as many deleted items as possible 
    // where the archived date is after a given date 
    // and the item path starts with a given path
    var itemsRemovedAfterSomeDate =
        archive.GetEntries(0, int.MaxValue)
                .Where(entry => 
                    entry.ArchiveDate > archiveDate && 
                    entry.OriginalLocation.StartsWith(pathPrefix)
                ).ToList();

    foreach (var itemRemoved in itemsRemovedAfterSomeDate)
    {
        // restore the item
        archive.RestoreItem(itemRemoved.ArchivalId);
    }
}
