    "timetosendsms" : null
}

This is my json string. What i need is to parse this string and store each values into specific members of a class.

The class is like this

public class Event
{

    public int id { get; set; }
    public string name {get;set;}
    public string text { get; set; }
    public DateTime start_date { get; set; }
    public DateTime end_date { get; set; }
    public string location { get; set; }
    public double ReminderAlert { get; set; }
    public MessagerType MessageType { get; set; }
    public string SmsMessage { get; set; }
    public string EmailMessage { get; set; }
    public string EmailSubject { get; set; }
    public DateTime TimeToSendEmail { get; set; }
    public DateTime TimeToSendSMS { get; set; }   
    public string[] members {get;set;}
}

I used Json.net library to parse..and my code snippet is given below

var eventValues = JsonConvert.DeserializeObject<List<Dictionary<string, Event>>>(stringEvent);

After running this code i get this error

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type ‘System.Collections.Generic.List1[System.Collections.Generic.Dictionary2[System.String,CalendarScheduler.Models.Event]]’ because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.

To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.

Path ‘id’, line 1, position 6.

What should be done to avoid this exception…?

Answer 1

This does not work?

var eventValues = JsonConvert.DeserializeObject<Event>(stringEvent);

And consider Oded’s comment. And match all JSON property names to C# property names.
