How do I add "Parent Reference item" to "File item List" using C#

Question

I'm trying to fetch Google Drive items & adding my own item dynamically for temporary use.

IList<File> Files = new List<File>();
FilesResource.ListRequest list = service.Files.List();
FileList filesFeed = list.Execute();

ParentReference pitem = new ParentReference();

File fileitem = new File();
fileitem.Id = RootId;
fileitem.Title = "MainDrive";
pitem.Id = null;
pitem.IsRoot = true;

fileitem.Parents.Add(pitem);

Files.Add(fileitem);

In the above code I'm able to add Google Drive file items plus my own fileitem to Files List.

To fetch the parent id I have to write the below code

(x => x.Files[0].Parent[0].Id)

But for the item which I added has fileitem.Parents itself is null, then how can I add parent id equal null(pitem.Id = null;)?? Throwing exception.

When i'm trying to add parent reference to List, It's throwing the error

"Object reference not set to an instance of an object."

Answer 1

Yes,I got it... fileitem.Parents = new List() { new ParentReference() { Id = _parent } };
