Getting File item all fields from SharePoint

Hi,

I am able to connect to sharepoint and download the files from a specific folder. Along with the file i need to create a metadata file which has to extracted from sharepoint. 

I am able to list all files using GetFiles, it returns a dictionary list, but this dictionary doesn’t have all the fields data (custom fields).

I was trying with GetListsItems but, it required List name and item id. is there any other way to get metadata from files while listing the files.

Thanks,

Sarath.
