Sharepoint client object model - Pull files from one site and move to another

Question

Dear All,
I am using client object model to retrieve files of certain criteria using caml query and copy them to some other site using 
client object model. There is no exception being thrown, but the application is not performing either. No files are being copied to destination. Here is the code. Please advise.
The message box that I have kept at the end is being displayed, but no files are being copied.

Hi,
To copy files from one site collection to another site collection, the simplest way is to open document library in windows explorer view.
Go to document library, click library tab, click open with explorer.
You can open the document library1 in explorer then copy the files which you want to paste to another site collection
document library2, then open the document library2 in explorer to paste the documents.
Besides, there are other method:
