If you look at your collection I think you will find that some documents have an ObjectId value for the _id, but your class declares ID to be a string.

What are you trying to accomplish?

c# driver version:1.4.0.4468

yes，i do

If you have documents that don't match your class declaration you will need to clean up your database first.

Still not sure what you are trying to accomplish, though. Your usage of the StringObjectIdGenerator is rather unusual. Why don't you just store your Ids as ObjectIds?
