I have a class, Foo, that looks like the following.
public class Foo { public ObjectId Id { get; set; } public string A { get; set; } public string B { get; set; } public string C { get; set; } }
And I map the class as follows
BsonClassMap.RegisterClassMap<Foo>(cm =>
{
cm.AutoMap();
cm.MapMember(c => c.A).SetOrder(3);
cm.MapMember(c => c.B).SetOrder(2);
cm.MapMember(c => c.C).SetOrder(1);
});
I expect my document to look like the following
> db.foo.findOne()
{
"_id" : ObjectId("58407cb1a589ca66b0d0ac48"),
"C" : "0",
"B" : "2016",
"A" : "Jan"
}
But they actually look like this.
> db.foo.findOne()
{
"_id" : ObjectId("58407bf8a589ca8f5cedb77b"),
"A" : "Jan",
"B" : "2016",
"C" : "0"
}
In order to get the desired order, I have to do the following mapping, making AutoMap last.
BsonClassMap.RegisterClassMap<Foo>(cm =>
{
cm.MapMember(c => c.A).SetOrder(3);
cm.MapMember(c => c.B).SetOrder(2);
cm.MapMember(c => c.C).SetOrder(1);
cm.AutoMap();
});
These should either be independent of order or we need to be explicit that SetOrder needs to come first.
