Insert a new field into an existing collection (many documents) in MongoDB using C# driver

Question

How can I insert a new field into a MongoDB collection using the C# Update API?

What I am trying to do: I have a HomePhoneId field that I need to insert into every document in my People collection.

Any ideas?

Following code should work:

collection.Update(Query.Null, Update.Set("HomePhoneId", "some value"), UpdateFlags.Multi)

Btw, here is you can look into driver documentation.
