I am currently following an online tutorial to create a RESTful API for MongoDB. The guide includes a DataAccess class for CRUD functionality. It is using the old MongoDB API which is now deprecated.There are three variables for Client, Server and Database and then has a constructor for the class:
MongoClient _client;
MongoServer _server;
MongoDatabase _db;
public DataAccess()
{
_client = new MongoClient("mongodb://localhost:27017");
_server = _client.GetServer();
_db = _server.GetDatabase("EmployeeDB");
}
The new API does not need the server variable so you just call directly on the client ( C# MongoDB.Driver GetServer is Gone, What Now? ) but I'm having trouble with the constructor. This is what I have but is throwing a "Cannot implicitly convert type" error for the _db line of code in the constructor:
MongoClient _client;
MongoDatabase _db;
public DataAccess()
{
_client = new MongoClient("mongodb://localhost:27017");
_db = _client.GetDatabase("Users");
}
MongoClient.GetDatabase
returns IMongoDatabase
interface.
Change your code to:
MongoClient _client;
IMongoDatabase _db;
public DataAccess()
{
_client = new MongoClient("mongodb://localhost:27017");
_db = _client.GetDatabase("Users");
}
