C# 取消序列化JSON字符串

我有这个密码

        string jsonString = "{\r\n  \"value1\":\"value2\" \r\n}";

        string normalString = "value4";

        NameValueCollection collection = new NameValueCollection();
        collection["First"] = jsonString;
        collection["Second"] = normalString;

        var nvcDictionary = collection.AllKeys.ToDictionary(k => k, k => collection[k]);

        var result = JsonConvert.SerializeObject(nvcDictionary);

产生

        {\"First\":\"{\\r\\n  \\\"value1\\\":\\\"value2\\\" \\r\\n}\",\"Second\":\"value4\"}

      {\"First\":\"value2\",\"Second\":\"value4\"}

但我想要这样

        {\"First\":\"{\"value1\":\"value2\"}\",\"Second\":\"value4\"}

        string jsonString = "{\r\n  \"value1\":\"value2\" \r\n}";

        string normalString = "value4";

        var parsedJson = JObject.Parse(jsonString);
        string valuefromJsonString = parsedJson["value1"].ToString();

        NameValueCollection collection = new NameValueCollection();
        collection["First"] = valuefromJsonString;
        collection["Second"] = normalString;

        var nvcDictionary = collection.AllKeys.ToDictionary(k => k, k => collection[k]);

        var result = JsonConvert.SerializeObject(nvcDictionary);

我试过了

        Regex.Unescape(jsonString);  

及

但我似乎无法在开始时“取消序列化”jsonString

为什么不在处理之前删除换行符

string jsonString = "{\r\n  \"value1\":\"value2\" \r\n}";
jsonString = jsonString.Replace(Environment.NewLine, "");

当我运行它时，结果的值为

"{\"First\":\"{  \\\"value1\\\":\\\"value2\\\" }\",\"Second\":\"value4\"}"

不是我想要的，但我会这样解决

        {\"First\":\"{\"value1\":\"value2\"}\",\"Second\":\"value4\"}

        string jsonString = "{\r\n  \"value1\":\"value2\" \r\n}";

        string normalString = "value4";

        var parsedJson = JObject.Parse(jsonString);
        string valuefromJsonString = parsedJson["value1"].ToString();

        NameValueCollection collection = new NameValueCollection();
        collection["First"] = valuefromJsonString;
        collection["Second"] = normalString;

        var nvcDictionary = collection.AllKeys.ToDictionary(k => k, k => collection[k]);

        var result = JsonConvert.SerializeObject(nvcDictionary);

产生

        {\"First\":\"{\\r\\n  \\\"value1\\\":\\\"value2\\\" \\r\\n}\",\"Second\":\"value4\"}

      {\"First\":\"value2\",\"Second\":\"value4\"}

如果您打算将json字符串转换为字典，则可以使用

JsonConvert.deserialize（）

方法将字符串反序列化为字典，然后基于该方法创建新字典

string jsonString = "{\r\n  \"value1\":\"value2\" \r\n}";
string normalString = "value4";
            
Dictionary<string, string> dict = JsonConvert.DeserializeObject<Dictionary<string, string>>(jsonString);
Dictionary<string, string> newDict = new Dictionary<string, string>()
{
    { "First", dict["value1"] },
    { "Second", normalString }
};
Console.WriteLine(JsonConvert.SerializeObject(newDict));

// Prints:
{"First":"value2","Second":"value4"}

string jsonString=“{\r\n\“value1\”：\“value2\”\r\n}”；
字符串normalString=“value4”；
Dictionary dict=JsonConvert.DeserializeObject（jsonString）；
字典newDict=新字典（）
{
{“第一”，dict[“value1”]}，
{“第二”，normalString}
};
WriteLine（JsonConvert.SerializeObject（newDict））；
//印刷品：
{“第一个”：“value2”，“第二个”：“value4”}
