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(lái)的時(shí)候往往是這樣

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

什么？無(wú)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(cè)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(méi)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",      "code": "8147056167227050270",      "title": "testing",      "type": "產(chǎn)品",      "status": "已處理",      "datetime": "2014-07-12T21:16:46",      "replycontent": "好的，只是測(cè)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": ""    }  ]}

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;  }}
