MongoDB with ASP.NET Core - Practical Examples

public class MongoDbService
{
    private readonly IMongoCollection<Person> _peopleCollection;

    public MongoDbService(IConfiguration configuration)
    {
        var client = new MongoClient(configuration.GetConnectionString("MongoDb"));
        var database = client.GetDatabase("TestDb");
        _peopleCollection = database.GetCollection<Person>("People");
    }

    public async Task<List<Person>> GetAsync() =>
        await _peopleCollection.Find(_ => true).ToListAsync();

    public async Task<Person> GetAsync(string id) =>
        await _peopleCollection.Find(p => p.Id == id).FirstOrDefaultAsync();

    public async Task CreateAsync(Person person) =>
        await _peopleCollection.InsertOneAsync(person);

    public async Task UpdateAsync(string id, Person person) =>
        await _peopleCollection.ReplaceOneAsync(p => p.Id == id, person);

    public async Task RemoveAsync(string id) =>
        await _peopleCollection.DeleteOneAsync(p => p.Id == id);
}

public class PeopleController : ControllerBase
{
    private readonly MongoDbService _mongoDbService;

    public PeopleController(MongoDbService mongoDbService)
    {
        _mongoDbService = mongoDbService;
    }

    [HttpGet]
    public async Task<IActionResult> Get() => Ok(await _mongoDbService.GetAsync());

    [HttpPost]
    public async Task<IActionResult> Create(Person person)
    {
        await _mongoDbService.CreateAsync(person);
        return CreatedAtAction(nameof(Get), new { id = person.Id }, person);
    }
}
