Question

I see lots of threads on copying files from one document library to another, but i want to move or copy a complete document library from one site to another (within the same site collection).

Is this possible with .NET C# code?

Answer 1

No, this is not possible – this is where specialized Backup solutions from third party vendors come in.

If you are talking about a simple document library it is of course not that hard:

• You first create a new document library at your destination and apply all your settings you have on your current library

• Secondly you just have to iterate over all documents in the library and use use the SPFolder.Add command

  SPFileCollection collFile = collFolder.Files;
foreach(SPFile file in collFile)
destFolder.Files.Add(file.Name, file.OpenBinary());

The collFolder in this case is the original document libary. The destFolder is the new document library. You can get the doc libs as a folder by using SPWeb.GetFolder(string doclibname).
