如何将为“ PayloadResponse”返回的字符串转换为HTTPResponse？我尝试了以下操作，但无法检索响应的正文：

var response = JObject.Parse(await httpResponseMessage.Content.ReadAsStringAsync());
var payloadResponse = response["ProcessCardSwipeOutputs"][0]["PayloadResponse"];


var msg = new HttpResponseMessage
{
   Content = new StringContent(payloadResponse.ToString(), Encoding.UTF8, "application/json")
};

这是我想转换为HttpResponse的PayloadResponse的内容，以便我可以以一种简洁的方式解析出响应主体：

HTTP/1.1 200 OKPragma: no-cache

            }
        ]
    }
}

如果我理解正确，那么您只想“以一种简洁的方式解析响应主体”。

您正在尝试将其转换为an，HttpResponseMessage因为您认为这将使所有内容都符合您的要求。这是一种干扰，听起来好像您想要创建一个响应并将其转发，但是您真正想要的只是将有效载荷解析为可用格式。

如我错了请纠正我。

要解析该有效负载，您可以在换行符（/u000a）上拆分该字符串，删除多余的内容&并解析json。

var splitResponse = payloadResponse.ToString().Split(new char[] { '\u000a' });

string body = splitResponse.Last().Substring(1);

JObject job = JObject.Parse(body);

// example
Console.WriteLine(job["messages"]["message"][0]["text"]);

我没有提供可以反序列化此json的类，因为它是一条错误消息，并且我假设您将不会总是在处理错误。成功响应可能是不同的模式。我不知道如何从您提供的信息中为此设计类，但也许可以使用JObject。
