官方文档没找见，自己在源码里面找到的

private string _dbHost = "bolt://localhost:7687";
private string _dbUser = "neo4j";
private string _dbPassword = "******";
private IDriver? _driver;

public CQLOperation(string _database = "neo4j")
{ 
    this.database = _database;
}

public string database { get; set; }

public string ExcuteQuery(string Cql)
{
    _driver = GraphDatabase.Driver(_dbHost, AuthTokens.Basic(_dbUser, _dbPassword));

    using (var session = _driver.Session(o => o.WithDatabase(database)))
    {
        var res = session.ExecuteRead(work =>
        {
            return work.Run(Cql).ToList();
        });

        string res_str = JsonConvert.SerializeObject(res);

        return res_str;
    }
}
