Download driver, new console project (. NET Core)

and add the MongoDB.dll 's Reference, NuGet searches MongoDB (current version 2.4.3).

Private Imongodatabase _database; private string _connstr = "mongodb://localhost:27017"; private string _dbname = "Vesseldb";

Create a database proxy class, link a database

Public Vesselrepository () { var client = new Mongoclient (_CONNSTR); _database = client. Getdatabase (_dbname); }

defining an Object

public class Vessel { [Bsonid] public int IMO {get; set;} [Bsonelement ("Vesselname")] public string Name {get; set;} [Bsonelement ("Portofregistry")] public string Registry {get; set;} [Bsonelement ("Yearofbuilt")] Public DateTime yearofbuilt {get; set;} }

The method of adding and modifying the deletion

Addmethod public void Addvessel (Vessel VSL) { _database. Getcollection<vessel> ("vessels"). Insertone (VSL); } Deletedmethod public void Deletevessel (string vslname) { var filter = Builders<vessel>. Filter.eq (VSL = VSL). Name, Vslname); _database. Getcollection<vessel> ("vessels"). Deleteone (filter); } Getmentod Public ienumerable<vessel> Getallvessels () { Return _database. Getcollection<vessel> ("vessels"). Find (FILTERDEFINITION<VESSEL>. Empty). ToList (); } UpdateMethod public void Updatevessel (int IMO, Vessel VSL) { var filter = Builders<vessel>. Filter.eq (v = v.imo, IMO); var update = Builders<vessel>. Update . Set (v = v.name, VSL. Name) . Set (v = v.registry, VSL. Registry) . Set (v = v.yearofbuilt, VSL. Yearofbuilt); _database. Getcollection<vessel> ("vessels"). Updateone (filter, update); }

It works perfectly.
