Question

我有一个包含以下数据的json字符串：

[
  {
    "RecordId": "1800",
    "CrewId": "M9703",
    "Rank": "3RD OFFICER",
    "VesselCode": "Honourable Henry Jackman",
    "MovementType": "ON LEAVE",
    "StartDate": "2009-01-13",
    "EndDate": "2012-06-30",
    "DueDate": "2009-01-02",
    "StartLoc": "",
    "EndLoc": "",
    "CompletionReason": "",
    "Remarks": "",
    "Last_Edited_Date": "2013-10-18"
  },
  {
    "RecordId": "4880",
    "CrewId": "M9703",
    "Rank": "2ND OFFICER",
    "VesselCode": "Ore Salobo",
    "MovementType": "ON LEAVE",
    "StartDate": "2013-02-10",
    "EndDate": "2013-08-26",
    "DueDate": "2012-12-28",
    "StartLoc": "",
    "EndLoc": "",
    "CompletionReason": "NORMAL DUTIES",
    "Remarks": "",
    "Last_Edited_Date": "2013-10-18"
  }
]

我想在控制台中将其显示为键值对。

我试过将它显示为键和值对：

string json = JsonConvert.SerializeObject(res);
var Dejson = JsonConvert.DeserializeObject<dynamic>(json);
foreach (var pair in Dejson)
{
    Console.WriteLine("{0}: {1}", pair.Key, pair.Value);
}

但它只在控制台中显示:。

Answer 1

       // assuming res is list of objects and RecordId is string not integer/long
        string json = JsonConvert.SerializeObject(res);

        Dictionary<string, res> Dejson = JsonConvert.DeserializeObject<dynamic>(json).ToDictionary(k => k.RecordId, v => v); 

        foreach ((KeyValuePair<string, res> pair in Dejson)
        {
            Console.WriteLine("{0}: {1}", pair.Key, pair.Value);
        }

Answer 2

JArray obj = JArray.Parse(json);    
Response.Write(obj[0]["RecordId"]);

使用上面的代码，您可以从JSon对象中获取所需的值。
