I am trying to parse a JSON string but I am getting an odd error:

Unable to cast object of type 'Newtonsoft.Json.Linq.JObject' to type 'Newtonsoft.Json.Linq.JProperty'

Would you check it and let me how I can get title values from this JSON string!

JArray theamackersSuggesionResult = JArray.Parse(json);
foreach (JObject parsedObject in theamackersSuggesionResult.Children<JObject>())

 foreach (JProperty parsedProperty in theamackersSuggesionResult)
 
 string propertyName = parsedProperty.Name;
 if (propertyName == "title")
 
 MessageBox.Show(parsedProperty.Value.ToString());
 KeywordSuggestionTable.Rows.Add(parsedProperty.Value.ToString());
 KeywordResultDataGrid.Refresh();
 
 

Try creating a model,

public class Example
 
 [JsonProperty("id")]
 public string id get; set; 

 [JsonProperty("title")]
 public string title get; set; 

 [JsonProperty("link")]
 public string link get; set; 

 [JsonProperty("is_answered")]
 public bool is_answered get; set; 
 

and use Newtonsoft to get the models from the json

var responseModels = JsonConvert.DeserializeObject<List<Example>>(json);

Then you can loop the responseModels to get what you want.

Also you can use this site -> http://json2csharp.com/

If you want to get model in C# of JSON data this site will be useful.

The error is due to this line:

foreach (JProperty parsedProperty in theamackersSuggesionResult)

It should be:

foreach (JProperty parsedProperty in parsedObject.Properties())
