我的课程只有私有字段和他们的公共 getter-setter。我需要将类对象转换为 JSON 字符串,因此我使用的是 JSON.Net。

以下是将类对象转换为 JSON 字符串的简单片段。

MyClass obj = new MyClass();
string json = JsonConvert.SerializeObject(obj);
Console.WriteLine(json);

但是该方法SerializeObject会抛出typeStackOverflowException的字段。这里发生了什么事?MyClassDateTime

以下是MyClass外观(实际上,我不介意分享实际课程)

                _FullLoad = value;
            }
        }
    }

此外,我将有另一个类,它将具有MyClass类型字段(以及它自己的类似字段集),它也将被转换为 JSON 字符串,这应该不是问题,因为据说 JSON.Net也支持这种情况。

注意:我是 C# 的新手,但我以前在 Java 中使用过 JSON,我可以在其中使用JSONObjectand JSONArray,而且它们非常简单。

看起来您的 TestEndTime 属性的 getter 引用了自己。因此,当 Json.NET 尝试对其进行序列化时,它会递归地访问自身并导致 StackOverflowException。

希望有帮助!
