c# SQL 到列表错误

真正的新手问题，我将不胜感激你能提供的任何支持。我正在尝试将SQL结果输出到列表中。但是当我返回列表时，我得到System.Collections.Generic.List'1[System.String]这是我的代码，有什么想法吗？提前谢谢你。

    public static List<string> GetDTSXPackages()
    {
        List<String> packages = new List<String>();
        using (SqlConnection connection = new SqlConnection(SQLConnectionString()))
        {
            string query = "SELECT PackageName FROM SharedServices.DTSXPackages";
            using (SqlCommand command = new SqlCommand(query, connection))
            {
                connection.Open();
                using (SqlDataReader reader = command.ExecuteReader())
                {
                    while (reader.Read())
                    {
                        packages.Add(reader["PackageName"].ToString());
                    }
                }
                connection.Close();
            }
        }
        return packages;
    }

    static void Main(string[] args)
    {
        List<string> x = SQLAccessLayer.GetDTSXPackages();
        foreach (var package in x)
        {
            Console.WriteLine(x);
        }
    }
