MongoDB C # Wrapper class (MongoDB Driver 1.9)

1. Installing the 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; The 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", "Ten}}}///</summary>       <param name= "Query" ></param>///<param name= "CollectionName" ></param> PU  Blic void Deleteby<t> (expression<func<t, bool>> whereexp, String collectionname) {var Collection = _db.            Getcollection<t> (CollectionName); Collection. Remove (QUERY&LT;T&GT;.        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&LT;T&GT;. Where (WHEREEXP)).        ToList (); } public T single<t> (expression<func<t, bool>> whereexp, string collectIonname) {return Search (Whereexp, CollectionName).        Single (); The public void Removecollection (string collectionname) {_db.        Dropcollection (CollectionName); public void Dispose () {_server.        Disconnect (); }    }

3 Examples of usage of some related operations

Query var driver = dbwrapper.single<driver> (d = d.name = = Name, dbcollectionname.for<driver> ()); var drivers = Dbwrapper.search<driver> (d = = D.name = = Name, dbcollectionname.for<driver> ()); Delete Dbwrapper.deleteby <Job> (j = j.id = = Id, dbcollectionname.for<publicqueue> ()); remove var updatingnw = update<network> from the collection . Pull (NW = NW. Jobs, ajobfromqueue);                Dbwrapper.update (QUERY<NETWORK>. Where (n = n.name = = Name), dbcollectionname.for<network> (), UPDATINGNW); Add new item to collection var UPDATINGDP = update< Dispatcher>. Addtoset<dynamic> (d = d.pendingjobs, ajobfromqueue);                Dbwrapper.update (QUERY<DISPATCHER>. Where (d = d.name = = Name), dbcollectionname.for<dispatcher> (), UPDATINGDP); Update Dbwrapper.update (query< Network>. Where (n = n.name = = Name), dbcollectionname.for<network> (), UPDATINGNW);
