Deserialize to Object with a List

问题

Im trying to parse an JSON response string to my class objects.. I can't figure this out and i need some help with this.

I use the json.net reference but i cant't find what i'm looking for :(

my json:

{

"@companyName": "Company Name",
"@version": "1.0",
"@generatedDate": "3/1/10 2:10 PM",
"application": [
    {
        "@name": "Application #1 name",
        "@apiKey": "1234",
        "@createdDate": "2010-03-01",
        "@platform": "Platform name"
    },
    {
        "@name": "Application #1 name",
        "@apiKey": "1234",
        "@createdDate": "2010-03-01",
        "@platform": "Platform name"
    }
]
}

my root class for the json is:

public class RootObject
{
    [JsonProperty]
    public string companyName { get; set; }

    [JsonProperty]
    public string version { get; set; }

    [JsonProperty]
    public string generatedDate { get; set; }

    [JsonProperty]
    public List<Application> application { get; set; }
}

my sub class (list of applications):

public class Application
{
    [JsonProperty]
    public string name { get; set; }

    [JsonProperty]
    public string apiKey { get; set; }

    [JsonProperty]
    public string createdDate { get; set; }

    [JsonProperty]
    public string platform { get; set; }
}

To parse it i have the following code now:

      JObject obj = JObject.Parse(e.Result);
      applications = new RootObject
            {
                companyName = (string) obj["companyName"],
                version = (string) obj["version"],
                generatedDate = (string) obj["generatedDate"],
                application = ???????? (how to make a list here?)

            }

Thanks in advance!

回答1:

Change your class definitions as follows

public class RootObject
{
    [JsonProperty("@companyName")]
    public string companyName { get; set; }

    [JsonProperty("@version")]
    public string version { get; set; }

    [JsonProperty("@generatedDate")]
    public string generatedDate { get; set; }

    public List<Application> application { get; set; }
}

public class Application
{
    [JsonProperty("@name")]
    public string name { get; set; }

    [JsonProperty("@apiKey")]
    public string apiKey { get; set; }

    [JsonProperty("@createdDate")]
    public string createdDate { get; set; }

    [JsonProperty("@platform")]
    public string platform { get; set; }
}

and deserialize

var rootObj = JsonConvert.DeserializeObject<RootObject>(myjson);

回答2:

Can you try the following code and report back any issues:

RootObject applications = JsonConvert.DeserializeObject<RootObject>(e.Result);

回答3:

A project I work on occasionally uses Json.Net. It's a wonderful library. I would use the JsonConvert.DeserializeObject method instead.

In your case I would try something like this:

var result = JsonConvert.DeserializeObject<RootObject>(yourJsonString);

That should take care of it.
