MongoDb C # Wrapper class,

MongoDb C # Wrapper class,

1. Install mongoDb Driver package

2. Use the Wrapper class:

 public class MongoDbWrapper : IDisposable    {        private MongoServer _server;        private MongoDatabase _db;        public MongoDbWrapper()        {            var uri = ConfigurationSettings.AppSettings["mongoUrl"];            var url = new MongoUrl(uri);            var client = new MongoClient(url);            _server = client.GetServer();            _db = _server.GetDatabase(url.DatabaseName);        }        public MongoDbWrapper BatchAdd<T>(T[] objArray, string collectionName)        {            var collection = _db.GetCollection<T>(collectionName);            collection.InsertBatch(objArray);            return this;        }        public MongoDbWrapper Add<T>(T obj, string collectionName)        {            var collection = _db.GetCollection<T>(collectionName);            collection.Insert(obj);            return this;        }        /// <summary>        /// e.g. { "Age", new BsonDocument { { "$gte", 10 } } }        /// </summary>        /// <param name="query"></param>        /// <param name="collectionName"></param>        public void DeleteBy<T>(Expression<Func<T, bool>> whereExp, string collectionName)        {            var collection = _db.GetCollection<T>(collectionName);            collection.Remove(Query<T>.Where(whereExp));        }        public void Update<T>(IMongoQuery query, string collectionName, T newObj) where T : IMongoUpdate        {            var collection = _db.GetCollection<T>(collectionName);            collection.Update(query, newObj);        }        public IEnumerable<T> Search<T>(Expression<Func<T, bool>> whereExp, string collectionName)        {            var collection = _db.GetCollection<T>(collectionName);            return collection.Find(Query<T>.Where(whereExp)).ToList();        }        public T Single<T>(Expression<Func<T, bool>> whereExp, string collectionName)        {            return Search(whereExp, collectionName).Single();        }        public void RemoveCollection(string collectionName)        {            _db.DropCollection(collectionName);        }        public void Dispose()        {            _server.Disconnect();        }    }
