读取包含所有空格和缩进的原始 JSON 字符串的一部分

Question

My client posts following json data in the body to my API, is there an easy way to get hold of the abc node's value (including the {} as well) as JSON string from HttpContext.Request.Body ? the most important thing is I need to keep all original spaces or indent if any .

PS the abc is always the first node, while def is the last node.

Thanks

{
   "abc": {
     ....
   },
   "def":"..."
}

Answer 1

You can try JObject which is part of Newtonsoft.Json library

using (StreamReader r = new StreamReader(filepath))
{
    string json = r.ReadToEnd();
    var jobject = JObject.Parse(json);
    var getabcvalue = jobject["abc"];
    Console.WriteLine(getabcvalue.ToString());
}

最终，我决定先从Stream读取字符串，然后使用Regex作为这种特殊情况的解决方案，我知道这不是很好，但是因为空格和缩进是关键要求之一，为了简单起见，我很乐意交易暂时关闭性能。
