Deserialize an IEnumerable<BsonDocument> into an IEnumerable<NominalType>

[Alex Brown]

Is it possible to use the BsonSerializer to Deserialize an IEnumerable<BsonDocument> into an IEnumerable<NominalType>?

Currently it seems I have to do something nasty like:

var result = new List<Discipline>();

            foreach (var item in bsonDocs)
                 result  .Add(BsonSerializer.Deserialize<MyNominalType>(item));

            return results;

See response to the same question in the mongodb-user group.

Thanks..

Had deleted that post due to this group (mongodb-csharp) being the right place for it...

not sure if posts can be moved across groups?

anyway, thanks again

I didn't realize you had deleted the post. I responded by email, which may have resurrected the post.

In any case, here's what I replied in mongodb-user:

BsonSerialize.Deserialize is designed to deserialize a single document at a time.

However, you could write your conversion from IEnumerable<BsonDocument> to IEnumerable<NominalType> on a single line of code:

    return bsonDocs.Select(b => BsonSerializer.Deserialize<MyNominalType>(b));

which is essentially doing the same thing but using the LINQ Select method.
