FiterDefinitionBuilder的使用

MemberDownloadData:对象数组
ImageInfo:实体模型

                var Imageinfo = MemberDownloadData.Select(p => new ObjectId(p.ImageId));
                FilterDefinitionBuilder<ImageInfo> builderFilter = Builders<ImageInfo>.Filter;
                FilterDefinition<ImageInfo> filter = builderFilter.In("_id", Imageinfo.ToArray());
                var img_data = await _repositoryImg.Find(filter, Builders<ImageInfo>.Projection
                    .Include(p => p._id)
                    .Include(p => p.ThumbnailPathList)
                    .Include(p => p.Title));
