C# MongoDB.Driver -如何形成构造函数

using MongoDB.Driver;

public class MongoDbManager
{
    private readonly IMongoDatabase _database;

    public MongoDbManager(string connectionString, string databaseName)
    {
        var client = new MongoClient(connectionString);
        _database = client.GetDatabase(databaseName);
    }

    // 其他操作方法...

    // 示例方法：获取集合
    public IMongoCollection<T> GetCollection<T>(string collectionName)
    {
        return _database.GetCollection<T>(collectionName);
    }
}

var connectionString = "mongodb://localhost:27017";
var databaseName = "mydatabase";

var manager = new MongoDbManager(connectionString, databaseName);

var collection = manager.GetCollection<MyDocument>("mycollection");
// 对集合进行操作...
