I am sharing my experience on the matter which worked for me. So basically the composition is the following for the string:

"mongodb://[user]:[password]@[host]:[port]"

and some example:

"mongodb://yourusername:yourpassword@localhost:27017"

I have used as refference the documentation here

Assuming user account was created in the admin database, and assuming you are using the command line interface (CLI) program called "mongo" you can connect to a 3 node replicaset with username and password with the following:

Syntax:

mongo --host "<replicaset name>/<host 1 resolvable name>:<host 1 port>,<host 2 resolvable name>:<host 2 port>,<host 3 resolvable name>:<host 3 port>" --username <username> --password <password> --authenticationDatabase <database name>

Example:

mongo --host "replset1/ip-172-31-48-110.eu-west-1.compute.internal:27017,ip-172-31-116-186.eu-west-1.compute.internal:27017,ip-172-31-29-140.eu-west-1.compute.internal:27017" --username barry --password supersecretpassword --authenticationDatabase admin

Like this:

var cliente = new MongoClient("mongodb://usuariocualquiera:tuclave@localhost:27017/BASEDEDATOS");

and could be call 

var collection = database.GetCollection<BsonDocument>("CUALQUIERCOLECCION");

With the C# driver you typically would not use the option of putting a database name on the connection string. It is partially supported to provide some level of compatibility with other drivers.

MongoServer.Create ignores the database name. Any credentials (username/password) on the connection string are used as default credentials for all databases.

The database name is only used by MongoDatabase.Create, which calls MongoServer.Create and then just calls GetDatabase for you.

So:

var connectionString = "mongodb://localhost/database";
var database = MongoDatabase.Create(connectionString);

is just a shortcut for:

var connectionString = "mongodb://localhost";
var server = MongoServer.Create(connectionString);
var database = server.GetDatabase("database");

No authentication actually happens until you first try to use a database.

You will create/return existing instance of the mongod process with user mongodb created in the admin database and password mongodb on localhost:27017. You shouldn't need to call Connect() - the driver will do this automatically as required.

It will connect to the named database. If the database is not present it will make a connection and upon creating a new object it will instantiate the database
