copy list items from one list to another in sharepoint

Question

In Sharepoint how can you copy a list item from one list to another list eg copy from \"List A\" to \"List B\" (both are at the root of the site)

I want this copying

Answer 1

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;
