如何在 Mongo C# 驱动程序中使用自动增量字段而不使用 eval？

我正在使用所讨论的自动增量字段here https://www.tutorialspoint.com/mongodb/mongodb_autoincrement_sequence.htm.

我可以在 Mongo Console 中执行这个示例，但是如何使用 c# 驱动程序实现这样的事情？

db.products.insert({
     "_id":getNextSequenceValue("productid"),
     "product_name":"Apple iPhone",
    "category":"mobiles"
})

是否可以在写操作中指定一个函数？

我可以使用 Eval 调用此函数，但由于它已被弃用，我想找到一个不使用它的解决方案。

举例来说here http://www.lybecker.com/blog/2014/06/27/mongodb-auto-increment-or-sequence/:

var client = new MongoClient(connectionString);
MongoServer server = client.GetServer();
MongoDatabase db = server.GetDatabase("myDatabase");
var counterCol = db.GetCollection("counters")

var result = counterCol.FindAndModify(new FindAndModifyArgs()
{
    Query = Query.EQ(d => d.Id, "orderId"),
    Update = Update.Inc(d => d.Value, 1),
    VersionReturned = FindAndModifyDocumentVersion.Modified,
    Upsert = true, //Create if the document does not exists
});

使用新的 v2.x 驱动程序：

public class Sequence
{
    [BsonId]
    public ObjectId _Id { get; set; }

    public string Name { get; set;  }

    public long Value { get; set;  }

    public void Insert(IMongoDatabase database)
    {
        var collection = database.GetCollection<Sequence>("sequence");
        collection.InsertOne(this);
    }

    internal static long GetNextSequenceValue(string sequenceName, IMongoDatabase database)
    {
        var collection = database.GetCollection<Sequence>("sequence");
        var filter = Builders<Sequence>.Filter.Eq(a => a.Name, sequenceName);
        var update = Builders<Sequence>.Update.Inc(a => a.Value, 1);
        var sequence = collection.FindOneAndUpdate(filter, update);

        return sequence.Value;
    }
}
