C# Mongo BsonSerializer.Deserialize Ignore elements that do not exist

Question

Is there a flat that will tell the C# Mongo BsonSerializer to ignore elements that do not exist in the poco class

Example collection

Animal {"Type" : "Cat", "Skill" : "Jump"}
Animal {"Type" : "Dog", "Skill" : "Bark", "Owner" : "Jimmy"}

If the cat C# class only has

public string Type {get;set;}
public string Skill {get;set;}

When I attempt to execute the following

 var test = BsonSerializer.Deserialize<Animal>(result);

The first item will work fine, the second one will throw an exception that Owner does not exist.

Answer 1

Use [BsonIgnoreExtraElements] attribute on Cat class.
From attribute summary:

Specifies whether extra elements should be ignored when this class is deserialized.
