Question

我有以下Json对象

   [


{
    "ID": 21,
    "Name": "Clement Rakesh",
    "DOB": "1983-07-07T00:00:00",
    "DOJ": "2014-07-30T00:00:00",
    "Address": "BANGALORE",
    "Mobile": 9611795983.0,
  },
  {
    "ID": 34,
    "Name": "Clement Rakesh",
    "DOB": "0001-01-01T00:00:00",
    "DOJ": "0001-01-01T00:00:00",
    "Address": "BANGALORE",
    "Mobile": 0.0,

  }
]

到目前为止，我所做的是：

using (StreamReader sr = new StreamReader(FILENAME))
 {
    string s = sr.ReadToEnd();
    JToken v = JArray.Parse(s);
    var emp = v.Where(x => x["ID"].ToString() ==empmodl.ID.ToString()).ToList();
  }

其中FILENAME是包含上述JSON对象的文件的路径。 emp包含要更新的必需对象。现在我需要更新原始JSON对象中的emp信息。有人可以帮忙吗？

Answer 1

我建议如下：

将JSON反序列化为对象
编辑对象
序列化回JSON

 var input = s;  

 //step 1
 dynamic yourJson = JObject.Parse(input);

 //step 2
 yourJson[0].Name = "test";

 //step 3
 string updatedJson = yourJson.ToString();

Answer 2

为什么不直接将整个JSON解析为对象，修改所需的一切并再次序列化？

using (StreamReader sr = new StreamReader(FILENAME))
 {
    string s = sr.ReadToEnd();
    dynamic jsonObject = JObject.Parse(s);
    var emp = v.Where(x => x["ID"].ToString() ==empmodl.ID.ToString()).ToList();

    //do the modifications here
    //write the contents to the file by using this
    JsonConvert.SerializeObject(jsonObject);
  }

搜索json对象并更新它
