Re: C# 2.0: Deserializing with convention pack

[Craig Wilson]

Hi Philip,

Sorry you are having trouble. To make a diagnosis, I'd need to see a more complete program. For instance, you are calling Find<T>... what is T? And what type is the collection? 

Regarding filter, you can use a BsonDocument as a filter, but it will not get mapping information applied to it. However, you can use the FilterDefinitionBuilder (Builders<Student>.Filter)  and use strings with it and it will get the mapping information applied.

Hi,

I am storing objects in my MongoDb, using a CamelCase pack. For example, an object like:

        public class Student : MongoObject

        {

            public string Name { get; set; }

            public int Year { get; set; }

        }

is stored like:

{

  "year : 2000",

  "name" : "Philip"

}

Now I want to deserialize the document into a Student object:

var filter = new BsonDocument();

var foundEnt = await collection.Find<T>(filter).FirstOrDefaultAsync();

However, the driver doesn't seem to understand the mapping, and it returns a Student object with null fields. 

Deserialization works fine when using the lambda format (which means that the camelcase is correctly registered), however, I need to use the BsonDocument-filter type for my current work.

Is this a bug or I am doing something wrong?

I see, sorry for insufficient data. I will simply use the FilterDefinitionBuilder to apply the mapping then.

Thanks!
