Question

first time i’m using MongoDB.

I have read this example:

SELECT a,b FROM users WHERE age=33
db.users.find({age:33}, {a:1,b:1})

But I can’t translate it into C#. Can anyone help me?

You can do it using SetFields method of MongoCursor class, below full example:

var server = MongoServer.Create(connectionString);
var db = _server.GetDatabase("dbName");
var users = db.GetCollection("users");

var cursor = users.FindAs<DocType>(Query.EQ("age", 33));
cursor.SetFields(Fields.Include("a", "b"));
var items = cursor.ToList();
