C#中如何格式化json字符串的方法分析

这篇文章主要介绍了C#格式化json字符串的方法,结合实例形式分析了C#针对json字符串格式化的原理、步骤与具体实现技巧,需要的朋友可以参考下

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，

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: 2014-07-12T21:16:46,
      replycontent: 好的，只是测试
    },

      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;
  }
}
