问题
I want to read Description, OutcomeDateTime, Team field which is inside Competitors array. I have tried JSON.Net but all the examples I found are pretty simple json feed but mine Json is quite complex. Can anyone suggest me how can I pull that fields into my C#?

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"],
};
回答2:
This code will show all the necessary fields:
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)));
}
}

Typist is right, you need to post your JSON to get better answers, in the mean time see if below helps,
Most browsers support JSON.parse(), which is defined in ECMA-262 5th Edition (the specification that JS is based on). Its usage is simple:
var json = '{"result":true,"count":1}', obj = JSON.parse(json);
alert(obj.count);
回答4:
Ignore this answer now as OP has posted the actual JSON. I'm keeping this in hope that this will still help somebody else.
If your Json string is like this -
[
"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",
}
]
Create a model class like -
public class Competitor
{
[JsonProperty("description")]
public string Description { get; set; }
[JsonProperty("team")]
public string Team { get; set; }
[JsonProperty("outcomeDateTime")]
public string OutcomeDateTime { get; set; }
}
You can deserialize like -
var competitors = JsonConvert.DeserializeObject<List<Competitor>>(jsonString);
回答5:
You need to have a class with all the properties which your json string contains , say for example you have that class called jsontext.
Use Json-Net to deserialize the response. To generate classes, you can use this generator which takes a Json input and outputs the C# classes associated.
//....
var responseObject = JsonConvert.DeserializeObject<RootObject>(jsontext);
}
this will convert your json string to that object values
