消息订阅接口中返回的json中，msg后面的值加了双引号

此问题导出json解析失败，请问是这是bug还是需要采用别的方式来解析呢？（对接语言  c#）

请看截图

麻烦您把返回的json复制一下发上来，不要截图，方便定位问题，谢谢。

https://www.youzanyun.com/docs/guide/3401/3449，您参考一下这里提供的解析方式，看看是否可以正确解析 ...

这里的是java和PHP的，没有C#的demo呀，您这边有C#的demo吗？

抱歉，目前还没有C#的demo，您看一下这个是否有帮助，https://www.cnblogs.com/yuanzijian-ruiec/p/97344 ...

好吧，我在看下，看看如何处理一下，不过话说为啥你们这个json的值会加一个双引号呢
