This is my first time using json.net and I can't figure it out. Here is my code below.
// Constructor
public MainPage()
{
InitializeComponent();
}
private void btnRefreshTweets_Click(object sender, RoutedEventArgs e)
{
string ServerURL = @"http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer/1/query?text=e&geometry=&geometryType=esriGeometryPoint&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&objectIds=&where=&time=&returnCountOnly=false&returnIdsOnly=false&returnGeometry=false&maxAllowableOffset=&outSR=&outFields=&f=json";
WebClient webClient = new WebClient();
webClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClient_DownloadStringCompleted);
webClient.DownloadStringAsync(new Uri(ServerURL));
}
void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error != null)
{
return;
}
List<Attributes> tweets = JsonConvert.DeserializeObject<List<Attributes>>(e.Result);
this.lbTweets.ItemsSource = tweets;
}
public class Attributes
{
public string STATE_NAME { get; set; }
}
I can't deserialize the STATE_NAME attributes. What am I missing?
I keep getting this error
"Cannot deserialize JSON object into type 'System.Collections.Generic.List`1[WPJsonSample.MainPage+Attributes]'. Line 1, position 20."
Here is your class structure ( I used http://json2csharp.com/)
public class FieldAliases
{
public string STATE_NAME { get; set; }
}
public class Field
{
public string name { get; set; }
public string type { get; set; }
public string alias { get; set; }
public int length { get; set; }
}
public class Attributes
{
public string STATE_NAME { get; set; }
}
public class Feature
{
public Attributes attributes { get; set; }
}
public class RootObject
{
public string displayFieldName { get; set; }
public FieldAliases fieldAliases { get; set; }
public List<Field> fields { get; set; }
public List<Feature> features { get; set; }
}
