这是我基于 Sam使用的可行解决方案我是的答案:

Here's the workable solution I used based off of Sam I am's answer:

dynamic obj = JsonConvert.DeserializeObject(json);
foreach (var response in (IEnumerable<dynamic>)obj.responses)
{
    response.body = JsonConvert.DeserializeObject((string)response.body);
}
string result = JsonConvert.SerializeObject(obj);
