我想读取Description, OutcomeDateTime, Team字段，这是在竞争者数组内。我尝试过JSON。但我发现的所有例子都是相当简单的json feed，但我的json相当复杂。有人能建议我如何把字段拉到我的c#中吗?

var json = new WebClient().DownloadString("http://4gp.tw/b036/1402972549560.txt");
var obj = JObject.Parse(json);
var query =
from JObject ev in obj.PropertyValues()
from JObject evid in ev.PropertyValues()
select new
{
Description = (string)evid["Description"],
OutcomeDateTime = Convert.ToDateTime((string)evid["OutcomeDateTime"]),
Teams =
from JObject comps in evid["Competitors"]["Competitors"]
select (string)comps["Team"],
};
下面的代码将显示所有必需的字段:
var parsedJson = JsonConvert.DeserializeObject<Dictionary<string, Dictionary<string, dynamic>>>(json);
foreach (var element in parsedJson)
{
Console.WriteLine(element.Key);
foreach (var item in element.Value)
{
Console.WriteLine(item.Key);
Console.WriteLine(item.Value.Description);
Console.WriteLine(item.Value.OutcomeDateTime);
IEnumerable<dynamic> competitors = item.Value.Competitors.Competitors;
Console.WriteLine(string.Join(",", competitors.Select(x => x.Team)));
}
}

打字员是对的，你需要发布你的JSON以获得更好的答案，同时看看下面是否有帮助，
大多数浏览器都支持JSON.parse()，它在ECMA-262第5版(JS基于的规范)中定义。它的用法很简单:
var json = '{"result":true，"count":1}'，obj = json .parse(json);
警报(obj.count);
现在忽略这个答案，因为OP已经发布了实际的JSON。我保存着这个，希望它仍然能帮助别人。
如果你的Json字符串是这样的-
[
"competitor":{
"description":"anything that you want to write",
"Team":"Team1",
"outcomeDateTime":"2014-06-16T05:01:10-04:00",
},
"competitor":{
"description":"anything that you want to write",
"team":"Team2",
"outcomeDateTime":"2014-06-16T05:01:10-04:00",
}
]
创建一个像-
这样的模型类public class Competitor
{
[JsonProperty("description")]
public string Description { get; set; }
[JsonProperty("team")]
public string Team { get; set; }
[JsonProperty("outcomeDateTime")]
public string OutcomeDateTime { get; set; }
}
你可以像-
那样反序列化var competitors = JsonConvert.DeserializeObject<List<Competitor>>(jsonString);
你需要有一个类，其中包含json字符串包含的所有属性，例如你有一个名为jsontext的类。
使用Json-Net来反序列化响应。要生成类，你可以使用这个生成器，它接受一个Json输入并输出相关的c#类。
//....
var responseObject = JsonConvert.DeserializeObject<RootObject>(jsontext);
}
这会将json字符串转换为对象值
