生成Mongo自增主键

public long GetSequence(string collectionName = "")
{
    MongoClient Client=new MongoClient(dbconn);
    if (string.IsNullOrEmpty(collectionName))
    {
        collectionName = typeof(T).Name;
    }
    var filter = Builders<Sequence>.Filter.Where(p => p.CollectionName == collectionName);
    var update = Builders<Sequence>.Update.Inc(x => x.Value, 1);
    var options = new FindOneAndUpdateOptions<Sequence, Sequence>() { ReturnDocument = ReturnDocument.After, IsUpsert = true };
    var seq = Client.GetDatabase(dbName).GetCollection<Sequence>("Sequence").FindOneAndUpdate(filter, update, options);
    return seq.Value;
}
public class Sequence
{
    public ObjectId Id { get; set; }
    public string CollectionName { get; set; }
    public long Value { get; set; }
}

Issue from

RunCommand with JsonCommand

public TResult RunCommand<TResult>(string json)
{
    new MongoClient(connectstring)
    .GetDatabase(dbname)
    .GetCollection<TDocument>()
    .RunCommand(new JsonCommand<TResult>(json));
}

Json格式文档参考
