原标题:Get a list of documents from Mongo DB

  • mongodb

我想做的是:

 List<int> fff = new List<int>();
 fff.Add(1);
 fff.Add(2);
 fff.Add(5);

 Mongo m = new Mongo();
 m.Connect();
 var dataBase = m.GetDatabase("database");
 var collection = dataBase.GetCollection("coll");

 IMongoQuery queryable = collection.AsQueryable();
        MongoQueryProvider prov = new MongoQueryProvider(collection);
        var query = new MongoQuery(prov);

 var ffppp = from p221 in query where fff.Contains((int)p221["oid"]) select p221;

这一错误: 不能将《公约》转化为《公约》。

我看到,下刚果省有1美元运营商。 是否有任何人知道我如何从c#中加以使用? (。 http://www.mongodb.org/display/DOCS/Advanced+Queries

最佳回答

在进行了更多的 go角之后,我发现:

var mongo = new Mongo();
var queryable = mongo["db"]["collection"].AsQueryable();
var in = from d in queryable where d.Key("foo").In("bar", "baz") select d;
