本文实例讲述了c#格式化json字符串的方法。分享给大家供大家参考,具体如下:

将json字符串转化成格式化表示的方法: 字符串反序列化为对象-->对象再序列化为字符串

使用newtonsoft.json提供的api,下载地址:http://www.newtonsoft.com/json

很多时候我们需要将json字符串以

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

这种方式显示,而从服务端取回来的时候往往是这样

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

什么?无所谓?

如果数据很庞大的时候,比如这样

复制代码 代码如下:
{"status":1,"totalcount":2,"list":[{"id":"2305b1e2-4e31-4fd3-8eb6-db57641914df","code":"8147056167227050270","title":"testing","type":"产品","status":"已处理","datetime":"2014-07-12t21:16:46","replycontent":"好的,只是测试"},{"id":"3a6546f6-49a7-4a17-b679-b3812b12b27e","code":"8147056167227050269","title":"我建议龙头有多种选配方式","type":"产品","status":"未处理","datetime":"2014-07-12t18:49:08.933","replycontent":""},{"id":"f735e461-ca72-4b44-8d7b-cd97ac09802f","code":"8147056167227050268","title":"这个产品不怎么好,不好用","type":"产品","status":"未处理","datetime":"2014-07-12t15:06:19.1","replycontent":""},{"id":"15926d9d-f469-4921-b01d-4b48ef8bd93d","code":"7141054273018032465","title":"jdjbcn","type":"服务","status":"未处理","datetime":"2014-05-27t01:03:46.477","replycontent":""},{"id":"1debf78f-42b3-4037-b71f-34075eed92bc","code":"4141051277003536211","title":"jdjbxn.x","type":"服务","status":"未处理","datetime":"2014-05-27t00:53:21.18","replycontent":""},{"id":"27593c52-b327-4557-8106-b9156df53909","code":"1143051276001357050","title":"ghggghh","type":"服务","status":"未处理","datetime":"2014-05-27t00:35:05.933","replycontent":""},{"id":"040198fc-b466-46c1-89d8-0514fbde9480","code":"4142053251166372433","title":"你好,你知道啦,我不喜欢白色浴缸","type":"服务","status":"未处理","datetime":"2014-05-25t16:37:43.853","replycontent":""},{"id":"16185418-d461-4e98-83c3-824eb7e344d6","code":"4145058213013197148","title":"hdjbchh","type":"服务","status":"未处理","datetime":"2014-05-21t01:19:14.903","replycontent":""},{"id":"6c043404-c1db-42e8-adeb-d4880fa7d1b5","code":"0142051185128085372","title":"ghhjdhd","type":"服务","status":"未处理","datetime":"2014-05-18t12:08:37.997","replycontent":""},{"id":"2dca1a38-a32b-4955-a99c-2ed7d6de60fa","code":"3146050186122030382","title":"hsibcn","type":"服务","status":"未处理","datetime":"2014-05-18t12:03:38.913","replycontent":""}]}

如果没有格式化,将很难查看。。。

使用下面的方法,将结果格式化为这样

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

      "datetime": "2014-05-18t12:03:38.913",
      "replycontent": ""
    }
  ]
}

实现代码如下:

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;
  }
}
