MongoDB C# Driver – Ignore fields on binding

February 9, 2023 by Tarik

Yes. Just decorate your UserModel class with the BsonIgnoreExtraElements attribute:

[BsonIgnoreExtraElements]
public class UserModel
{
    public ObjectId id { get; set; }
    public string Email { get; set; }
}

As the name suggests, the driver would ignore any extra fields instead of throwing an exception. More information here – Ignoring Extra Elements.
