Case insensitive property mapping


When serializing a MongoDB document to a POCO is there any way to make properties map case insensitive? For example I'd like this document:

{ "id": "1" "foo": "bar" }

to map to this class:

public MyObj { public int Id {get; set;} public string Foo {get; set;} }


To do that I think you will have 2 options.

The first would be to write out a class map manually

BsonClassMap.RegisterClassMap<MyClass>(cm => { cm.AutoMap(); cm.GetMemberMap(c => c.Foo).SetElementName("foo"); });

The second would be to decorate your class with the following attributes

public class MyObj { [BsonElement("id")] public int Id { get; set; } [BsonElement("foo")] public string Foo { get; set; } }

The CSharp driver team have a good tutorial on serialization on the following link

I have just tried the following and this works for me, obviously I'm sure this is a much more simplified version of your code but taking a guess at how it might look.

I have registered the two class maps separately and added the BsonKnownType to the base class.

[BsonKnownTypes(typeof(GeoJSONObject))] public class Point { public string Coordinates { get; set; } } public class GeoJSONObject : Point { public string Type { get; set; } } static void Main(string[] args) { var cn = new MongoConnectionStringBuilder("server=localhost;database=MyTestDB;"); var settings = MongoClientSettings.FromConnectionStringBuilder(cn); var client = new MongoClient(settings); BsonClassMap.RegisterClassMap<Point>(cm => { cm.AutoMap(); cm.GetMemberMap(c => c.Coordinates).SetElementName("coordinates"); }); BsonClassMap.RegisterClassMap<GeoJSONObject>(cm => { cm.AutoMap(); cm.GetMemberMap(c => c.Type).SetElementName("type"); }); var result = client.GetServer() .GetDatabase("MyTestDB") .GetCollection("MyCol") .Find(Query.EQ("type", BsonValue.Create("xxxx"))); }
