An error message of type 'Newtonsoft.Json.JsonReaderException' occured in System.Private.CoreLib.ni.dll and was not user-handled Unexpected character found while reading value: [

I have utilized this JSON format for both my iOS and Android applications with no issues. jsonlint.com has confirmed the validity of the JSON structure. It is puzzling why there is an issue with the [ character.

Answer №1

If your JSON code is incomplete due to a copying error, the issue you are experiencing is likely caused by an incorrect model class. Your current model class has a property named browse_content that is expecting a string value, but the deserializer is attempting to assign an array from the JSON data to this property, resulting in the error message concerning the unexpected character [. To resolve this, simply update your model class as follows:

public class JSON_Browse_Root
{
    public List<JSON_Browse_Content> browse_content { get; set; }
}
