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://HdhCmsTestnewtonsoft测试数据/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" ,

]
}
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;
}
}
