get Infopath form id after add into Formlibrary

Question

I want try to get Infopath form id after add to form library by following code

spFile = fileLibrary.Files.Add(fileName, fileContents, replaceExistingFiles);

and I can't access spFile.Item.Id because I added file to form library and I receive this error:

The object specified does not belong to a list.

Is there any efficient way to get id by name? I tried to get id by file URL but there is no Item.Id again.

Answer 1

The properties are case sensitive in SharePoint. Normally its ID

So try below code

spFile.Item.ID

This should solve the problem.
