using System.Collections.Generic;
using System.Web.Script.Serialization;

namespace CPTemp
{
    public class Class1
    {
        static void Main(string[] args)
        {
            string input = "{\"Errors\":[{\"Code\":123,\"Message\":\"Your account is Linked\"}]}";
            JavaScriptSerializer js = new JavaScriptSerializer();
            ErrorInfo obj = js.Deserialize<ErrorInfo>(input);
            foreach (ErrorDescription item in obj.Errors)
            {
                string message = item.Message;
                int code = item.Code;
            }
        }
    }

    public class ErrorDescription
    {
        public string Message { get; set; }
        public int Code { get; set; }
    }

    public class ErrorInfo
    {
        public List<ErrorDescription> Errors { get; set; }
    }
}
