Convert .NET Guid to MongoDB ObjectID

Question

How can I convert a .NET GUID to a MongoDB ObjectID (in C#). Also, can I convert it back again to the same GUID from the ObjectID?

Answer 1

although not a direct answer keep in mind that there is no.requirement that _id be an ObjectID --- only that it be unique.

any valid type can be set for _I'd including an embedded object or a . you should be fine (barring any uniqueness violations) using a GUID for _id; in fact, ObjectID is really just a custom GUID.
