C#格式化json字符串的方法分析

來源：本站原創(chuàng)|時(shí)間：2020-01-10|欄目：C#教程|點(diǎn)擊：次

本文實(shí)例講述了C#格式化json字符串的方法。分享給大家供大家參考，具體如下：

將Json字符串轉(zhuǎn)化成格式化表示的方法: 字符串反序列化為對(duì)象-->對(duì)象再序列化為字符串

使用Newtonsoft.Json提供的API，下載地址：http://www.newtonsoft.com/json

很多時(shí)候我們需要將json字符串以

{
  "status": 1,
  "sum": 9
}

這種方式顯示，而從服務(wù)端取回來的時(shí)候往往是這樣

{"status": 1, "sum": 9}

什么？無所謂？

如果數(shù)據(jù)很龐大的時(shí)候，比如這樣

復(fù)制代碼代碼如下:

{"status":1,"totalcount":2,"list":[{"id":"2305b1e2-4e31-4fd3-8eb6-db57641914df","code":"8147056167227050270","title":"testing","type":"產(chǎn)品","status":"已處理","datetime":"2014-07-12T21:16:46","replycontent":"好的，只是測試"},{"id":"3a6546f6-49a7-4a17-b679-b3812b12b27e","code":"8147056167227050269","title":"我建議龍頭有多種選配方式","type":"產(chǎn)品","status":"未處理","datetime":"2014-07-12T18:49:08.933","replycontent":""},{"id":"f735e461-ca72-4b44-8d7b-cd97ac09802f","code":"8147056167227050268","title":"這個(gè)產(chǎn)品不怎么好，不好用","type":"產(chǎn)品","status":"未處理","datetime":"2014-07-12T15:06:19.1","replycontent":""},{"id":"15926d9d-f469-4921-b01d-4b48ef8bd93d","code":"7141054273018032465","title":"jdjbcn","type":"服務(wù)","status":"未處理","datetime":"2014-05-27T01:03:46.477","replycontent":""},{"id":"1debf78f-42b3-4037-b71f-34075eed92bc","code":"4141051277003536211","title":"jdjbxn.x","type":"服務(wù)","status":"未處理","datetime":"2014-05-27T00:53:21.18","replycontent":""},{"id":"27593c52-b327-4557-8106-b9156df53909","code":"1143051276001357050","title":"ghggghh","type":"服務(wù)","status":"未處理","datetime":"2014-05-27T00:35:05.933","replycontent":""},{"id":"040198fc-b466-46c1-89d8-0514fbde9480","code":"4142053251166372433","title":"你好，你知道啦，我不喜歡白色浴缸","type":"服務(wù)","status":"未處理","datetime":"2014-05-25T16:37:43.853","replycontent":""},{"id":"16185418-d461-4e98-83c3-824eb7e344d6","code":"4145058213013197148","title":"hdjbchh","type":"服務(wù)","status":"未處理","datetime":"2014-05-21T01:19:14.903","replycontent":""},{"id":"6c043404-c1db-42e8-adeb-d4880fa7d1b5","code":"0142051185128085372","title":"ghhjdhd","type":"服務(wù)","status":"未處理","datetime":"2014-05-18T12:08:37.997","replycontent":""},{"id":"2dca1a38-a32b-4955-a99c-2ed7d6de60fa","code":"3146050186122030382","title":"hsibcn","type":"服務(wù)","status":"未處理","datetime":"2014-05-18T12:03:38.913","replycontent":""}]}

如果沒有格式化，將很難查看。。。

使用下面的方法，將結(jié)果格式化為這樣

{
  "status": 1,
  "totalcount": 2,
  "list": [
    {
      "id": "2305b1e2-4e31-4fd3-8eb6-db57641914df",

    }
  ]
}

實(shí)現(xiàn)代碼如下：

private string ConvertJsonString(string str)
{
  //格式化json字符串
  JsonSerializer serializer = new JsonSerializer();
  TextReader tr = new StringReader(str);
  JsonTextReader jtr = new JsonTextReader(tr);
  object obj = serializer.Deserialize(jtr);
  if (obj != null)
  {
    StringWriter textWriter = new StringWriter();
    JsonTextWriter jsonWriter = new JsonTextWriter(textWriter)
    {
      Formatting = Formatting.Indented,
      Indentation = 4,
      IndentChar = ' '
    };
    serializer.Serialize(jsonWriter, obj);
    return textWriter.ToString();
  }
  else
  {
    return str;
  }
}
