我试图使用一个API,使用以下示例结构为他们返回的json

[
   {
      "customer":{
         "first_name":"Test",
         "last_name":"Account",
         "email":"test1@example.com",
         "organization":"",
         "reference":null,
         "id":3545134,
         "created_at":"2013-08-06T15:51:15-04:00",
         "updated_at":"2013-08-06T15:51:15-04:00",
         "address":"",
         "address_2":"",
         "city":"",
         "state":"",
         "zip":"",
         "country":"",
         "phone":""
      }
   },
   {
      "customer":{
         "first_name":"Test",
         "last_name":"Account2",
         "email":"test2@example.com",
         "organization":"",
         "reference":null,
         "id":3570462,
         "created_at":"2013-08-12T11:54:58-04:00",
         "updated_at":"2013-08-12T11:54:58-04:00",
         "address":"",
         "address_2":"",
         "city":"",
         "state":"",
         "zip":"",
         "country":"",
         "phone":""
      }
   }
]

JSON.net可以使用类似以下结构的东西

{
    "customer": {
        ["field1" : "value", etc...],
        ["field1" : "value", etc...],
    }
}

但我无法弄清楚如何让它对提供的结构感到满意.

使用默认的JsonConvert.DeserializeObject(content)会生成正确的Customer数,但所有数据都为null.

在CustomerList(下面)执行某些操作会导致"无法反序列化当前JSON数组"异常

public class CustomerList
{
    public List<Customer> customer { get; set; }
}

思考？

我正在寻找一个示例代码/ lib来使用C#解码JSON字符串.

编码我可以这样做:

var data = new Dictionary<string,string>(); 
data.Add("..", "..."); 
var json_encoded = new JavaScriptSerializer().Serialize(data); 

但我怎么解码？

var json_decoded = ?? 

我有一个json字符串,它是通过序列化一个对象数组创建的:

[
    {
        "html": "foo"
    },
    {
        "html": "bar"
    }
]

如何将其反序列化为某个可迭代的C#结构？我试过这段代码,但是我收到了No parameterless constructor defined for type of 'System.String'.错误:

string[] htmlArr = new JavaScriptSerializer().Deserialize<String[]>(html);

我想要获得的是一个可迭代的结构来获取每个'html'对象.

我正在使用ObjectForScripting属性与WebBrowser控件内的网页进行交互,一切正常,但我无法弄清楚如何将字符串数组传递回C#

HTML代码

<input type="submit" onclick="window.external.save(Array('test', 'test2'))" />

形成

// Returns System.__ComObject
public void Save(object parameters)
{
}

// Throws an exception
public void Save(object[] parameters)
{
}

// Also throws an exception
public void Save(string[] parameters)
{
}

假设我的json存储在字符串变量中.我的json看起来像

"{\"file\":\"dave\",\"type\":\"ward\"}"

上面的数据存储在我的字符串变量中.现在我如何反序列化这个json数据并读取每个组件,如文件和类型.

我尝试使用以下代码但收到错误

 var jss = new JavaScriptSerializer();
 string json = new StreamReader(context.Request.InputStream).ReadToEnd();

 var sData=jss.Deserialize<string>(json);
 string _file = sData[0].ToString();
 string _type = sData[1].ToString();

请指导我如何从json格式的数据反序列化后,如何提取文件和类型等每个组件.谢谢

纠正

这样我解决了这个....这里是整个客户端和服务器端代码.

     <script type="text/javascript">
     $(document).ready(function () {
         $('#btnlogin').click(function (e) {
             var FeedCrd = {};
             FeedCrd["file"] = 'dave';
             FeedCrd["type"] = 'ward';

             $.ajax({
                 type: "POST",
                 url: "CallASHX.ashx",
                 data: JSON.stringify(FeedCrd),
                 //data: { 'file': 'dave', 'type': 'ward' },
                 //dataType: "json",
                 success: function (data) {
                     if (data == "SUCCESS");
                     {
                         alert('SUCCESS');
                     }

                 },
                 error: function (XMLHttpRequest, textStatus, errorThrown) {
                     alert(textStatus); …

I'm trying to work with the google maps api. This URL is EXACTLY what I need:

http://maps.googleapis.com/maps/api/geocode/json?address=77379

Take a look at the results. It has all the info I need... lat, lon, state, country. Trouble is, I don't know how to extract this data. I tried this:

var client = new WebClient();
var content = client.DownloadString("http://maps.googleapis.com/maps/api/geocode/json?address=77379");
object myObject = JsonConvert.DeserializeObject(content);

While that doesn't error out, myObject doesn't end up being anything useful. (Or, maybe it is and I just don't …

我使用的API返回具有一些属性的公司符号的集合，但是我不知道如何反序列化它

{
    "A": {
        "advanced-stats": {
            "prop1": 0.198791,
            "prop2": 16.59,
            "prop3": 12.44,
        }
    },
    "AA": {
        "advanced-stats": {
            "prop1": 0.198791,
            "prop2": 16.59,
            "prop3": 12.44,
        }
    },
    "AAAU": {
        "advanced-stats": {
            "prop1": 0.198791,
            "prop2": 16.59,
            "prop3": 12.44,        
        }
    }
}

对我的网络请求的响应如下（不在我的控制之下）：

{
"nasdaq_imbalance": 
{
    "name": "nasdaq_imbalance", 
    "group": "Market Data", 
    "description": null
},
"DXOpen IM": 
{
    "name": "DXOpen IM", 
    "group": "Daily",
    "description": null
}, 
"Float Shares": 
{
    "name": "Float Shares", 
    "group": "Daily", 
    "description": null
}, 

}

不知何故，我需要将它反序列化为包含对象列表的 C# 对象......基本上我需要一个这样的对象列表：

public class Dataset    {
    public string name { get; set; } 
    public string group { get; set; } 
    public string description { get; set; } 
}

我正在尝试解析一个JsonArray很多个小时,我通过graph.facebook得到了,所以我可以得到额外的值.我想要提取的值是消息和ID.

获得JasonArry是没问题的并且工作正常:

[
    {
    "code":200,
    "headers":[{"name":"Access-Control-Allow-Origin","value":"*"}],
    "body":"{
        \"id\":\"255572697884115_1\",
        \"from\":{
            \"name\":\"xyzk\",
            \"id\":\"59788447049\"},
        \"message\":\"This is the first message\",
        \"created_time\":\"2011-11-04T21:32:50+0000\"}"},
    {
    "code":200,
    "headers":[{"name":"Access-Control-Allow-Origin","value":"*"}],
    "body":"{
        \"id\":\"255572697884115_2\",
        \"from\":{
             \"name\":\"xyzk\",
             \"id\":\"59788447049\"},
        \"message\":\"This is the second message\",
        \"created_time\":\"2012-01-03T21:05:59+0000\"}"}
]

现在我已经尝试了几种方法来访问消息,但每个方法都以catch结尾...并抛出异常.

例如:

var serializer = new JavaScriptSerializer();   
var result = serializer.Deserialize<dynamic>(json);

foreach (var item in result)
{
    Console.WriteLine(item.body.message);
}

抛出异常:System.Collections.Generic.Dictionary不包含body的定义.不过你在下面的截图中看到,该主体包含定义.

Becaus我不允许发布你可以在directupload上找到的图片:http://s7.directupload.net/images/120907/zh5xyy2k.png

我没有更多的想法,所以我请你帮助我.我需要这个项目,私有,而不是商业.

也许你可以给我一个代码短语,所以我可以继续我的发展.

谢谢你到目前为止

嗨我收到了来自网络服务的回复,我希望从回复中获得一个网址.我的回答是以下格式.

我需要"cdn_streaming_uri"作为名称"test3".

您可以在http://json.parser.online.fr/中查看JSON解析器. 如何解析它？

这是我的代码:
