MongoDb CurrentDate with setonInsert -


with $currentdate can set timestamp field server datetime.

this looks this:

updatedefinition<mydto> update = updates    .currentdate(x => x.servertimestamp);    .setoninsert(x => x.timestamp, commit.timestamp)

but in want use setoninsert method. date set created documents not updated

is there way c# driver?
