How can I get the Owner name of a file that is shared with me using file id or preview url

How can I get the Owner name or email of a file that is shared with me using file id or file preview url.

I am using .Net SDK.

Thanks

This depends on what kind of sharing you're referring to.

If the file is in a shared folder that you are a member of, you can use the ListFolderMembersAsync and ListFolderMembersContinueAsync methods to get the list of members, and check which one is the owner.

If the file has been individually shared with you, you can use GetFileMetadataAsync to get the metadata for the shared file, including the OwnerDisplayNames if available.

If you have a shared link for a file, you can use GetSharedLinkMetadataAsync to get the metadata for the shared link, including TeamMemberInfo, if the links owner's is a member of the same team.

Hi,

Thanks for quick response.

In my case  file has been individually shared with me,

when I am trying to get the metadata of the file using  GetFileMetadataAsync and file id as a parameter to get the metadata of the shared file why OwnerDisplayNames is null?

Code :

var FileMetaData = await dc_Member.Sharing.GetFileMetadataAsync(SharedFile.Id);

Unfortunately, the OwnerDisplayNames value can't always be fetched, though I don't have more specific information to share on when/why that is the case. I'll send this along to the team to ask to get this better documented though.
