Convert Json String to C# Object List

You can use json2csharp.com to Convert your json to object model

• Go to json2csharp.com
• Past your JSON in the Box.
• Clik on Generate.
• You will get C# Code for your object model
• Deserialize by var model = JsonConvert.DeserializeObject<RootObject>(json); using NewtonJson

Here, It will generate something like this:

public class MatrixModel
{
    public class Option
    {
        public string text { get; set; }
        public string selectedMarks { get; set; }
    }

    public class Model
    {
        public List<Option> options { get; set; }
        public int maxOptions { get; set; }
        public int minOptions { get; set; }
        public bool isAnswerRequired { get; set; }
        public string selectedOption { get; set; }
        public string answerText { get; set; }
        public bool isRangeType { get; set; }
        public string from { get; set; }
        public string to { get; set; }
        public string mins { get; set; }
        public string secs { get; set; }
    }

    public class Question
    {
        public int QuestionId { get; set; }
        public string QuestionText { get; set; }
        public int TypeId { get; set; }
        public string TypeName { get; set; }
        public Model Model { get; set; }
    }

    public class RootObject
    {
        public Question Question { get; set; }
        public string CheckType { get; set; }
        public string S1 { get; set; }
        public string S2 { get; set; }
        public string S3 { get; set; }
        public string S4 { get; set; }
        public string S5 { get; set; }
        public string S6 { get; set; }
        public string S7 { get; set; }
        public string S8 { get; set; }
        public string S9 { get; set; }
        public string S10 { get; set; }
        public string ScoreIfNoMatch { get; set; }
    }
}

Then you can deserialize as:

var model = JsonConvert.DeserializeObject<List<MatrixModel.RootObject>>(json);

public static class Helper
{
    public static string AsJsonList<T>(List<T> tt)
    {
        return new JavaScriptSerializer().Serialize(tt);
    }
    public static string AsJson<T>(T t)
    {
        return new JavaScriptSerializer().Serialize(t);
    }
    public static List<T> AsObjectList<T>(string tt)
    {
        return new JavaScriptSerializer().Deserialize<List<T>>(tt);
    }
    public static T AsObject<T>(string t)
    {
        return new JavaScriptSerializer().Deserialize<T>(t);
    }
}
