Insert data or document into collection with C# and MongoDB

The InsertOneAsync method and the InsertManyAsync method are used to add documents to a collection in MongoDB. If documents to a collection that does not exist, MongoDB will create the collection.

We can use InsertManyAsync while inserting more than one document.

Follow the Install and Connect to MongoDB step to connect to a running MongoDB instance.
