Can't connect c# to mongoDb

Question

I'm trying to connect to a program coded in C# to a mongoDB. I have created a new collection and I have inserted some data . I'm using mlab as host for my dataBase.

MongoClientSettings settings = new MongoClientSettings();
settings.Server = new MongoServerAddress("ds145128.mlab.com", 45128);
MongoClient client = new MongoClient(settings);

var db = client.GetDatabase("unknowndb");
var coll = db.GetCollection<Book>("book");

Please help me, when I execute the program, it show me a error message that I can't connect to the DB?

Answer 1

I connected like that

var connectionString = ConfigurationManager.ConnectionStrings[CONNECTION_STRING_NAME].ConnectionString;
var mongoUrl = new MongoUrl(connectionString);
var client = new MongoClient(mongoUrl);
var database = client.GetDatabase(mongoUrl.DatabaseName);

And my connection string like this. I connected to local mongodb. You can use MongoUrl

mongodb://[username:password@]host1[:port1][/[database][?options]]

mongodb://localhost:27017/dbtest?readPreference=primary

Thanks a lot for you answers, this is how to connect with mongodb c# driver 2.0.1

   static void Main(string[] args)
    {
        Task t = MainAsync(args);
        t.Wait();
    }

    static async Task MainAsync(string[] args)
    {
        var client = new MongoClient("mongodb://localhost:27017/test");
        var db = client.GetDatabase("name");
        var coll = db.GetCollection<Book>("collName");}
