解析aspx中的JSON对象 [英] Parse JSON Object in aspx

问题描述

我有如下的JSON对象.

I have JSON Object as below.

[{"articleLeader":"","articlePostDate":{"date":12,"day":4,"hours":0,"minutes":0,"month":10,"seconds":1,"time":1258012801000,"timezoneOffset":480,"year":109},"articleTitle":"AZ United Care Home LLC","author":"","webPageFileName":"AZ_United_Care_Home.html","webPageURI":"/AZ_United_Care_Home.html"},
 {"articleLeader":"","articlePostDate":{"date":12,"day":4,"hours":0,"minutes":0,"month":10,"seconds":1,"time":1258012801000,"timezoneOffset":480,"year":109},"articleTitle":"Baldris Home Care","author":"","webPageFileName":"Baldris_Home_Care.html","webPageURI":"/Baldris_Home_Care.html"},
 {"articleLeader":"","articlePostDate":{"date":12,"day":4,"hours":0,"minutes":0,"month":10,"seconds":1,"time":1258012801000,"timezoneOffset":480,"year":109},"articleTitle":"Basia Residential Care","author":"","webPageFileName":"Basia_Residential_Care.html","webPageURI":"/Basia_Residential_Care.html"}]

我想从该对象中提取诸如author，articleTitle之类的参数.

我该怎么办.

推荐答案

当我在aspx页面中调用JSON servlet接口时，我将这个JSON对象作为webResponse获得.

Hi I am getting this JSON object as webResponse when I call JSON servlet Interface in aspx page.

try
       {

           string URL = "http://xapi-content.jbossdev/json";

           string content = "service=contentService&method=getArticlePagesByService¶ms=<a class="\"array\""><e type="\"string\"" key="\"webSiteName\"">www.testecl.com</e><e type="\"string\"" key="\"serviceCode\"">Senior_Home_Care</e><e type="\"string\"" key="\"maxCount\"">3</e><e type="\"string\"" key="\"sortOrder\"">ARTICLE_SORT_BY_TITLE_ACENDING</e></a>";
           //Console.WriteLine(URL);


           HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(URL);
           webRequest.Credentials = CredentialCache.DefaultCredentials;
           webRequest.Method = "POST";
           webRequest.ProtocolVersion = HttpVersion.Version11;
           webRequest.ContentType = "application/x-www-form-urlencoded";
           webRequest.ContentLength = content.Length;
           Stream requestStream = webRequest.GetRequestStream();
           ASCIIEncoding encoding = new ASCIIEncoding();
           byte[] array = encoding.GetBytes(content);
           requestStream.Write(array, 0, array.Length);
           requestStream.Flush();
           requestStream.Close();


           HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();

           string jsonResponse = string.Empty;
           using (StreamReader sr = new StreamReader(webResponse.GetResponseStream()))
           {
               jsonResponse = sr.ReadToEnd();

           }
           Response.Write(jsonResponse);


       }
       catch (Exception objExp)
       {
           Console.WriteLine(objExp.ToString());
       }

   }

所以现在我在``jsonResponse''字符串变量中有了这个JSON字符串.

我只是aspx开发的初学者，这是我的第一个项目.

我已经从http://json.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=37810
下载了Json.NET 3.5 Release 6
现在我不知道如何实现此库并解析JSON字符串.

请指导.

So Now I have this JSON string in my ''jsonResponse'' string variable.

I am just starter in aspx devlopment, this is my first project.

I have downloaded Json.NET 3.5 Release 6 from http://json.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=37810

Now I do not know How to implement this library and parse JSON string.

Please guide.

使用JavaScriptSerializer 解析JSON对象.

说

Use JavaScriptSerializer to parse JSON objects.

Say

string json = yourjsonstring;

现在使用:

Now use :

JavaScriptSerializer ser = new JavaScriptSerializer();
var jsonobj= ser.Deserialize(json);

只需将yourjsonscript放在字符串变量中，然后将其反序列化为您自己的对象即可.您也可以定义一个类而不是使用匿名类型. :cool:

Just place yourjsonscript in the string variable and Deserialize it to your own object. You can also define a class rather than using an annonymous type. :cool:

它给了我下面的错误.


错误1找不到类型或名称空间名称"JavaScriptSerializer"(您是否缺少using指令或程序集引用?)C:\ ElderCare \ ArticleData.aspx.cs

错误3找不到类型或名称空间名称"var"(您是否缺少using指令或程序集引用?)C:\ ElderCare \ ArticleData.aspx.cs 74 13 C:\ ElderCare \


我不明白如何将jsonscript放入字符串变量并将其反序列化为您的对象

Hi It gave me below error.


Error 1 The type or namespace name ''JavaScriptSerializer'' could not be found (are you missing a using directive or an assembly reference?) C:\ElderCare\ArticleData.aspx.cs

Error 3 The type or namespace name ''var'' could not be found (are you missing a using directive or an assembly reference?) C:\ElderCare\ArticleData.aspx.cs 74 13 C:\ElderCare\


I did not understand How do I place jsonscript in the string variable and Deserialize it to your my object
