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

{"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": [

}

]

}

这样就容易多了.代码没做错误处理，读者可自行更改

需要导入Newtonsoft.Json，这里使用的版本是4.5

                            
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;
           
}         
       
}
