JSON DeserializeObject error for a string and an object (array)

Question

This is my JSON value

{ "spatialReference": 
    { "wkid": 4326, "latestWkid": 4326 }, 
 "candidates": 
  [ 
      { "address": "380 New York St, Redlands, California, 92373",   "location": { "x": -117.19564110200449, "y": 34.057084093752607 }, "score": 99.890000000000001, "attributes": { } }, 
      { "address": "380 New York St, Redlands, California, 92373", "location": { "x": -117.19564235064003, "y": 34.057118309276547 }, "score": 99.890000000000001, "attributes": { } }, 
      { "address": "381 New York St, Redlands, California, 92373", "location": { "x": -117.19570747666533, "y": 34.057117640108572 }, "score": 78.890000000000001, "attributes": { } }, 
      { "address": "New York St, Redlands, California, 92373", "location": { "x": -117.19564313410432, "y": 34.054959327808675 }, "score": 99.890000000000001, "attributes": { } }, 
      { "address": "92373, Redlands, California", "location": { "x": -117.18448413080158, "y": 34.042938592774277 }, "score": 100, "attributes": { } }, 
      { "address": "Redlands, California", "location": { "x": -117.18259971082223, "y": 34.055564407815503 }, "score": 98.780000000000001, "attributes": { } } 

  ]
  }

This is code:

public class CanAttributes
    {
        public string StreetName { get; set; }
        public string StreetType { get; set; }
    }

    public class Candidates
    {
        [JsonProperty("address")]
        public string Address { get; set; }
        [JsonProperty("location")]
        public GeoLocation Location { get; set; }
        [JsonProperty("score")]
        public decimal Score { get; set; }
        [JsonProperty("attributes")]
        public CanAttributes Attributes { get; set; }
    }

    public class jsCandidates
    {
        [JsonProperty("spatialReference")]
        public string spatialReference { get; set; }  
         [JsonProperty("candidates")]
        public Candidates[] candidates { get; set; }
    }

    public class GeoLocation
    {
        [JsonProperty("x")]
        public decimal X { get; set; }

        [JsonProperty("y")]
        public decimal Y { get; set; }
    }



   jsCandidates canArray = JsonConvert.DeserializeObject<jsCandidates>(str);

It gives me "Error reading string. Unexpected token: StartObject. Path 'spatialReference', line 2, position 23" when I tried to deserialized the above json value. Any help would be appreciated.

It seems like you have declared wrong properties names in class GeoLocation. You declared them as Lat and Long while in your JSON they are x and y. Also, i would recommend you to use JSON 2 C#: json2csharp.com — denied

I edited the code to make it's more clear, but the issue still exist. — Jenny

Not string, you should change to object.

public string spatialReference { get; set; }

Or this instead:

public class SpatialReference
{
    public int wkid { get; set; }
    public int latestWkid { get; set; }
}
