The issue CSHARP-1521 occurs again in the newest 2.10.2 C# Driver. Error message:
The serializer for field 'MyDictionary' must implement IBsonArraySerializer and provide item serialization info.
Model is definied like this:
public class Model { public Dictionary<long, Guid> MyDictionary { get; set; } }
ClassMap is registered as below:
BsonClassMap.RegisterClassMap<Model>(cm =>
{
cm.AutoMap();
cm.MapProperty(c => c.MyDictionary).SetSerializer(new DictionaryInterfaceImplementerSerializer<Dictionary<long, Guid>>(DictionaryRepresentation.ArrayOfDocuments));
});
My query:
Builders<Model>.Filter.ElemMatch(request => request.MyDictionary, f => f.Value.Equals(value));
And I have a workaround that works for me, but I don't want to use it in long term:
public class DictionaryArrayInterfaceImplementerSerializer<TDictionary, TKey, TValue> : DictionaryInterfaceImplementerSerializer<TDictionary>, IBsonArraySerializer where TDictionary : class, IDictionary, new() { public DictionaryArrayInterfaceImplementerSerializer(DictionaryRepresentation dictionaryRepresentation) : base(dictionaryRepresentation) { } public bool TryGetItemSerializationInfo(out BsonSerializationInfo serializationInfo) { var serializer = new KeyValuePairSerializer<TKey, TValue>(); serializationInfo = new BsonSerializationInfo( null, serializer, serializer.ValueType); return true; } }
Basically I can create new serializer, which inherits from DictionaryInterfaceImplementerSerializer, but also implements IBsonArraySerializer and then everything works.
