I\'m trying to deserialize a Facebook friend\'s Graph API call into a list of objects. The JSON object looks like:
{\"data\":[{\"id\":\"518523721\",\"name\"
Here is another site that will help you with all the code you need as long as you have a correctly formated JSON string available:
https://app.quicktype.io/
Very easily we can parse JSON content with the help of dictionary and JavaScriptSerializer. Here is the sample code by which I parse JSON content from an ashx file.
var jss = new JavaScriptSerializer();
string json = new StreamReader(context.Request.InputStream).ReadToEnd();
Dictionary<string, string> sData = jss.Deserialize<Dictionary<string, string>>(json);
string _Name = sData["Name"].ToString();
string _Subject = sData["Subject"].ToString();
string _Email = sData["Email"].ToString();
string _Details = sData["Details"].ToString();
You need to create a structure like this:
public class Friends
{
public List<FacebookFriend> data {get; set;}
}
public class FacebookFriend
{
public string id {get; set;}
public string name {get; set;}
}
Then you should be able to do:
Friends facebookFriends = new JavaScriptSerializer().Deserialize<Friends>(result);
The names of my classes are just an example. You should use proper names.
Adding a sample test:
string json =
@"{""data"":[{""id"":""518523721"",""name"":""ftyft""}, {""id"":""527032438"",""name"":""ftyftyf""}, {""id"":""527572047"",""name"":""ftgft""}, {""id"":""531141884"",""name"":""ftftft""}]}";
Friends facebookFriends = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<Friends>(json);
foreach(var item in facebookFriends.data)
{
Console.WriteLine("id: {0}, name: {1}", item.id, item.name);
}
Produces:
id: 518523721, name: ftyft
id: 527032438, name: ftyftyf
id: 527572047, name: ftgft
id: 531141884, name: ftftft
Sometimes I prefer dynamic objects:
public JsonResult GetJson()
{
string res;
WebClient client = new WebClient();
// Download string
string value = client.DownloadString("https://api.instagram.com/v1/users/000000000/media/recent/?client_id=clientId");
// Write values
res = value;
dynamic dyn = JsonConvert.DeserializeObject(res);
var lstInstagramObjects = new List<InstagramModel>();
foreach(var obj in dyn.data)
{
lstInstagramObjects.Add(new InstagramModel()
{
Link = (obj.link != null) ? obj.link.ToString() : "",
VideoUrl = (obj.videos != null) ? obj.videos.standard_resolution.url.ToString() : "",
CommentsCount = int.Parse(obj.comments.count.ToString()),
LikesCount = int.Parse(obj.likes.count.ToString()),
CreatedTime = new System.DateTime(1970, 1, 1, 0, 0, 0, 0).AddSeconds((double.Parse(obj.created_time.ToString()))),
ImageUrl = (obj.images != null) ? obj.images.standard_resolution.url.ToString() : "",
User = new InstagramModel.UserAccount()
{
username = obj.user.username,
website = obj.user.website,
profile_picture = obj.user.profile_picture,
full_name = obj.user.full_name,
bio = obj.user.bio,
id = obj.user.id
}
});
}
return Json(lstInstagramObjects, JsonRequestBehavior.AllowGet);
}
