I want this copying

Answer 1

private void CopyAttachmentsToList(SPListItem srcItem, SPListItem tgtItem)
{
    try
    {
        //get source item attachments from the folder
        SPFolder srcAttachmentsFolder =
            srcItem.Web.Folders["Lists"].SubFolders[srcItem.ParentList.Title].SubFolders["Attachments"].SubFolders[srcItem.ID.ToString()];

        //Add items to the target item
        foreach (SPFile file in srcAttachmentsFolder.Files)
        {
            byte[] binFile = file.OpenBinary();
            tgtItem.Update();
            tgtItem.Attachments.AddNow(file.Name, binFile);
            tgtItem.Update();
        }
    }
    catch
    {
        //exception message goes here
    }
    finally
    {
        srcItem.Web.Dispose();
    }
}

Don't forget to add this line, tgtItem.Update();, else you will get an err.

How to copy field and save versions:

public static SPListItem CopyItem(SPListItem sourceItem, SPList destinationList)
            {
                SPListItem targetItem = destinationList.AddItem();

                //loop over the soureitem, restore it
                for (int i = sourceItem.Versions.Count - 1; i >= 0; i--)
                {
                    //set the values into the archive 
                    foreach (SPField sourceField in sourceItem.Fields)
                    {
                        SPListItemVersion version = sourceItem.Versions[i];

                        if ((!sourceField.ReadOnlyField) && (sourceField.InternalName != "Attachments"))
                        {
                            SetFields(targetItem, sourceField, version);
                        }
                    }

                    //update the archive item and 
                    //loop over the the next version
                    targetItem.Update();
                }

                foreach (string fileName in sourceItem.Attachments)
                {
                    SPFile file = sourceItem.ParentList.ParentWeb.GetFile(sourceItem.Attachments.UrlPrefix + fileName);
                    targetItem.Attachments.Add(fileName, file.OpenBinary());
                }

                targetItem.SystemUpdate();
                return targetItem;
            }

            private static bool SetFields(SPListItem targetItem, SPField sourceField, SPListItemVersion version)
            {
                try
                {
                    targetItem[sourceField.InternalName] = version.ListItem[sourceField.InternalName];
                    return true;
                }
                catch (System.ArgumentException)//field not filled
                {
                    return false;
                }
                catch (SPException)//field not filled
                {
                    return false;
                }
            }

Indeed as Lars said, it can be tricky to move items and retain versions and correct userinfo. I have done similar things with that before so if you need some code examples, let me know through a comment and can supply you with some guidance.

The CopyTo method (if you decide to go with that) need an absolute Uri like: http://host/site/web/list/filename.doc

So, if you are performing this in an event receiver you need to concatinate a string containing the elements needed. Something like (note that this can be done in other ways to):

string dest= 
 siteCollection.Url + "/" + site.Name + list.Name + item.File.Name;

Answer 4

Make sure you call CopyTo(url) method on SPFile, not on SPListItem. for example:

ItemUpdated(SPItemEventProperties properties)
{ 
  //...
  string url = properties.Web.Site.Url + "/" + properties.Web.Name + "Lists/ListName/" + properties.ListItem.File.Name;
  //properties.ListItem.File.MoveTo(url);
  properties.ListItem.File.CopyTo(url);
  //...
}

Here is a powershell equivalent of Sylvian's that does allow for cross-site copy. His code could be modified similarly as well...

param([string]$sourceWebUrl, [string]$sourceListName, [string]$destWebUrl, [string]$destListName)

$sourceWeb = get-spweb $sourceWebUrl;
$sourceList = $sourceWeb.Lists[$sourceListName];
$destWeb = get-spweb $destWebUrl;
$destList = $destWeb.Lists[$destListName];
$sourceList.Items |%{
$destItem = $destList.Items.Add();
$sourceItem = $_;
$sourceItem.Fields |%{
    $f = $_;
    if($f.ReadOnlyField -eq $false -and $f.InternalName -ne "Attachments" -and $sourceItem[$f.InternalName] -ne $null){
        $destItem[$f.InternalName] = $sourceItem[$f.InternalName];
    }
}
$destItem.Update();
}

To use, copy and past to a file copy-listitems.ps1 and run using Sharpoint powerhsell commandline...

Copy List Items from one SharePoint List or library to Another SharePoint list or library using c# server side code

//Itecollection is a collection of data from source list

 public void CopyItemsFromOneListToAnotherList(SPListItemCollection itemCollection)
 {  
 using (SPSite site = new SPSite(siteUrl))
 {
  using (SPWeb web = site.OpenWeb())
  {
     //Get destination list/library
     //destListName - Destination list/library name
   SPList destList = web.Lists.TryGetList(destListName);

   foreach (SPListItem sourceItem in itemCollection)
   {
    //Add new Item to list
    SPListItem destItem = destList.Items.Add();

    foreach (SPField field in sourceItem.Fields)
    {
     if (!field.ReadOnlyField && !field.Hidden && field.InternalName != "Attachments")
     {
      if (destItem.Fields.ContainsField(field.InternalName))
      {
       //Copy item to  destination library
         destItem[field.InternalName] = sourceItem[field.InternalName];
      }
     }
    }
    //Update item in destination  library or list
    destItem.Update();
    Console.WriteLine("Copied " + sourceItem["ID"] + "to destination list/library");
   }
  }
 }

 }
