Question

I have to update all the fields except _id.
I want to avoid to manually update the 16 fields…
All the new fields are stored inside a BsonDocument

Thanks for ideas

As @Philipp hinted there is a way way to do this. You can actually use the save function ( http://www.mongodb.org/display/DOCS/CSharp+Driver+Tutorial#CSharpDriverTutorial-Save%3CTDocument%3Emethod ) which will do what he says for you in the database end.

So imagine you have a document of:

{
    _id: {},
    d: 1
}

And that _id already exists, it will replace the previous document with this one.

Neat huh?
