将大型 httpresponse 流转换为 JSON 字符串？
Converting large httpresponse stream to a JSON string?
问题背景：
更新：
我仍然不确定如何从该回复中提取相关信息。我已尝试将我的响应类型设置为 JSON 但仍然收到如下所示的响应。我已经考虑了关于使用 NameValueCollection 的内容，但仍然看不出这对如此大的响应有何帮助。理想情况下，我希望将其映射到某种对象结构，它不一定必须是 JSON.
问题：
我目前正在使用 PayPal Api 'ExpressCheckout' 方法允许用户为我的测试站点上的项目付款。来自 API 的 HTTP 响应提供了一个包含我需要提取的关键信息的大型响应 - 例如买家地址、付款是否成功等。
问题:
目前我对如何处理响应感到困惑。理想情况下，我会将数据转换为 JSON 字符串，然后使用 Newtonsoft 将数据映射到 C# 类，从而允许轻松访问数据。这是 Httpresponse 的示例：

如果有人能给我一种将此数据映射到 C# 对象的简单方法，那就太好了。
您想要 JSON 格式有什么具体原因吗？如果它不是必需的，并且如果您可以接受键值对，那么这里是您可以将响应作为键值对处理的一种方法。

仍然不确定将其作为 NameValueCollection 处理有什么问题。
例如
//NameValueCollection
//or use HttpUtility.ParseQueryString(some_string_of_names_values)
var foo = Request.QueryString;
var bar = foo["FIRSTNAME"]; //based on above this is "Joe"
更新：
It is response string which is being processed here and not request hence you wont be able to retrieve details using Request.QueryString
如评论所述：
string rawResponse = "TOKEN=EC%2XXXXXXXXXXXXXXXXXR&BILLINGAGREEMENTACCEPTEDSTATUS=0&CHECKOUTSTATUS=PaymentActionNotInitiated&TIMESTAMP=2015%2d01%2d02T21%3a11%3a30Z&CORRELATIONID=ab184fdba7a30&ACK=Success&VERSION=88...."
var foo = HttpUtility.ParseQueryString(rawResponse); //NameValueCollection
var bar = foo["FIRSTNAME"]; //Joe
