如何寫C＃查詢到JSON文件

Question

我不得不修改我的JSON文件在我的C＃項目，但我得到了一些problems.Moreover，我使用json.net

我的JSON文件deathGod.json：

{ 
    "toKillList": [ 
    { 
     "Name": "John", 
     "dieWith": "eat hot dog", 
     "Date": "date", 
     "State": "state" 
    }, 
    { 
     "Name": "peter", 
     "dieWith": "swim", 
     "Date": "date", 
     "State": "state" 
    } 
    ] 
} 

我的編碼：

string path = @"\users\deathGod\documents\visual studio 2012\Projects\killApp\killApp\deathGod.json"; 
string jsonData = File.ReadAllText(path); 

dynamic result = JsonConvert.DeserializeObject(jsonData); 
JArray items = (JArray)result["toKillList"]; 

問題：

我需要向JArray添加查詢，然後將Jarray添加到JObject。但是，引號和換行符會殺死我的文件。

代碼：

string element = @"{'Name':’may’, 
        ‘Path’:’driving’, 
        ‘Date’:’date’, 
        ‘State’:’state’}"; 

JValue value = new JValue(element); 
items .Add(value); 
//JArray => JObject => json file 

結果：

{ 
    "toKillList": [ 
     { 
      "Name": "John", 
      "dieWith": "eat hot dog", 
      "Date": "date", 
      "State": "state" 
     }, 
     { 
      "Name": "peter", 
      "dieWith": "swim", 
      "Date": "date", 
      "State": "state" 
    }, 
    "{'Name':’may’, \r\n‘Path’:’driving’,\r\n ‘Date’:’date’,\r\n ‘State’:’state’\r\n}" 
    ] 
} 

什麼想法？如果你想字符串轉換成JSON首先與'取代’

var element = JObject.FromObject(new 
{ 
    Name = "may", 
    Path = "driving", 
    Date = "date", 
    State = "state" 
}); 
items.Add(element); 

Answer 1

你應該建立JObject而不是JValue。然後使用下面的代碼：

var element = @"{'Name':'may','Path':'driving', 'Date':'date', 'State':'state'}"; 

var value = (JToken)JsonConvert.DeserializeObject(element); 
items.Add(value); 

var res = JsonConvert.SerializeObject(result); 

最終的結果是：

{ 
    "toKillList":[ 
    {"Name":"John","dieWith":"eat hot dog","Date":"date","State":"state"}, 
    {"Name":"peter","dieWith":"swim","Date":"date","State":"state"}, 
    {"Name":"may","Path":"driving","Date":"date","State":"state"} 
    ] 
}
