}
and I am unable to parse the result into an array/list of Hotspot objects. I've tried the following:
var json = response.Content.ReadAsStringAsync().Result;
HotspotArray hotspotArray = JsonConvert
.DeserializeObject<HotspotArray>(json);
Hotspot[] hotspots = hotspotArray.Hotspots;
var hotspotNames = "";
for (int i = 0; i < hotspots.Length; i++)
{
hotspotNames += hotspots[i].Name + " ";
}
output.Text = hotspotNames;
}
}
}
public class HotspotArray
{
[JsonProperty("WebHotspotList")]
public Hotspot[] Hotspots { get; set; }
}
public class Hotspot
{
[JsonProperty("address")]
public string Address { get; set; }
[JsonProperty("rewards_total")]
public decimal RewardsTotal { get; set; }
[JsonProperty("geo_long_city")]
public string GeoLongCity { get; set; }
[JsonProperty("geo_long_country")]
public string GeoLongCountry { get; set; }
[JsonProperty("geo_long_state")]
public string GeoLongState { get; set; }
[JsonProperty("geo_long_street")]
public string GeoLongStreet { get; set; }
[JsonProperty("geo_short_city")]
public string GeoShortCity { get; set; }
[JsonProperty("geo_short_country")]
public string GeoShortCountry { get; set; }
[JsonProperty("geo_short_state")]
public string GeoShortState { get; set; }
[JsonProperty("block")]
public int Block { get; set; }
[JsonProperty("block_added")]
public int BlockAdded { get; set; }
[JsonProperty("location")]
public string Location { get; set; }
[JsonProperty("name")]
public string Name { get; set; }
[JsonProperty("nonce")]
public int Nonce { get; set; }
[JsonProperty("owner")]
public string Owner { get; set; }
[JsonProperty("score")]
public decimal Score { get; set; }
[JsonProperty("score_update_height")]
public int ScoreUpdateHeight { get; set; }
[JsonProperty("lat")]
public decimal Lat { get; set; }
[JsonProperty("lng")]
public decimal Lon { get; set; }
[JsonProperty("status_gps")]
public string StatusGPS { get; set; }
[JsonProperty("status_height")]
public int StatusHeight { get; set; }
[JsonProperty("status_online")]
public string StatusOnline { get; set; }
[JsonProperty("geo_short_street")]
public string GeoShortStreet { get; set; }
[JsonProperty("geo_city_id")]
public string GeoCityID { get; set; }
}
However the data keeps coming back null...hotspots array is null. What am I missing here? TIA

Top-level in your json is Type with property Done. Create type:
public class HotspotResponse
{
public HotspotArray Done { get; set; }
}
and deserialize json string into this class.
