For more please read our writing reference. Use InsertMany or BulkWrite to insert multiple documents at once. Inserting the first document will create collection named "Games" var games = database.GetCollection("Games") Same happens when we create a database, the first structure inside a database will implicitly create it. If a collection does not exist, the first write operation will implicitly create it. Use the InsertOne method to create a single document inside a collection. ![]() In the sample application, this is a Game type, which is a class we defined with the same properties as the field in our document.

Now that we have a client, it is time to connect to the database using this client and begin to add in the CRUD functionality. This service was created to give us access to all the CRUD operations. Once you have your connection string, you can create an instance of the client and pass it in as per below, replacing the template string below with your connection string : var client = new our sample application, the client is created inside a GamesService class. A commonly used secure source for information in. In production we recommend placing the string and passwords in a secure source not exposed as a clear text code.
