Google api ドット ネット クライアントを使用していますが、少し混乱しています。
次のコードは、特定のフォルダーのリスト全体を返します (ID: XXXXXXXXXXXXXXXXXXXXX)。
List<File> result = new List<File>();
FilesResource.ListRequest request = service.Files.List();
request.Q = "'XXXXXXXXXXXXXXXXXXXXX' in parents";
request.MaxResults = 35;
FileList files = request.Fetch();
例として、この FileList の 1 つの項目は
"id": "0B5XhOfl0NZ2cZ1M1aVBPcVlTUTA",
"title": "87BC1CAE-A01C-43A1-BB21-BE3DA6D6C7DC"
タイトルを検索してクエリを変更すると、常に空の FileList が返されます。
List<File> result = new List<File>();
FilesResource.ListRequest request = service.Files.List();
request.Q = "title = '87BC1CAE-A01C-43A1-BB21-BE3DA6D6C7DC'";
request.MaxResults = 35;
FileList files = request.Fetch();
演算子が '=' または 'contains' であるか、またはディレクトリ名の一部のみを検索するかは問題ではありません。
title contains '87BC1CAE'
ID を検索するだけで正しい結果が得られます。次のコードは問題なく動作します。
File file = service.Files.Get(fileId).Fetch();
Console.WriteLine("Title: " + file.Title);
Console.WriteLine("Description: " + file.Description);
Console.WriteLine("MIME type: " + file.MimeType);
助けてください :)

ご覧のとおり、アイテム数は0です。
