            //Create database object

            IMongoCollection<UserInfo> collection = database.GetCollection<UserInfo>(collectionName);
            collection.InsertOne(userObject);

            //Retrieving one object
            UserInfo retrievedObject;
            FilterDefinition<UserInfo> theFilter = Builders<UserInfo>.Filter.Eq(p => p.FirstName, "Bob");
            retrievedObject = collection.Find<UserInfo>(theFilter).First();

How to connect MongoDb Database from application

Define parameters

private static IMongoClient _client;
private static IMongoDatabase _database;
private static IMongoCollection< -collection class name- > _collection;
 

Assign values to parameters

_client = new MongoClient("mongodb://localhost:27017");
_database = _client.GetDatabase("database name here");
_collection = _database.GetCollection< -collection class name- >("collection name here");
