如何将对象转换为JSON表示形式 [英] How do I convert an object to JSON representation

问题描述

奇怪的是，我没有找到这个.

Oddly enough, I didn't find this.

将对象转换为JSON字符串的最简单方法是什么? (对象图中的循环等边缘情况对我来说并不重要.让我们找到一种简单的类A的解决方案，其中包含一些B，C，D类对象和一些基元).

What's the simplest way to convert an object to a JSON string? (Edge cases like loops in the object graphs aren't of much interest to me. Let's find a solution to the simple case of class A that contains some objects of classes B,C,D and some primitives).

必须有基本的收藏支持.

Basic collection support is a must.
