在sgmoore的链接中发布了对象转储器：

YAML也很好地达到了这个目的，这就是使用YamlDotNet可以做到的

install-package YamlDotNet

    private static void DumpAsYaml(object o)    {        var stringBuilder = new StringBuilder();        var serializer = new Serializer();        serializer.Serialize(new IndentedTextWriter(new StringWriter(stringBuilder)), o);        Console.WriteLine(stringBuilder);    }
