Parsing JSON into a List of Objects

Here is a filter string in the following format:

{"groupOp":"AND","rules":[{"field":"FName","op":"bw","data":"te"}]}

I am looking to deserialize this into a Generic list of items.

Any tips on how I can accomplish this?

Answer №1

Check out JSON.NET. With this tool, you can perform tasks such as:

JObject o = new JObject(
  new JProperty("Name", "John Smith"),
  new JProperty("BirthDate", new DateTime(1983, 3, 20))
);

JsonSerializer serializer = new JsonSerializer();
Person p = (Person)serializer.Deserialize(new JTokenReader(o), typeof(Person));

Console.WriteLine(p.Name);
// John Smith

Refer to the documentation for more information.

Answer №2

To deserialize the JSON data, you can utilize the JavaScriptSerializer class as demonstrated below:

Code for Deserialization

using System.Web.Script.Serialization;

...

string jsonData = "{\"groupOp\":\"AND\",\"rules\":[{\"field\":\"FName\",\"op\":\"bw\",\"data\":\"te\"}]}";
JavaScriptSerializer serializer = new JavaScriptSerializer();
Filter filter = (Filter)serializer.Deserialize<Filter>(jsonData);

Custom Classes

public class Filter
{
    public string GroupOp { get; set; }
    public List<Rule> Rules { get; set; }

    public Filter()
    {
        Rules = new List<Rule>();
    }
}

public class Rule
{
    public string Field { get; set; }
    public string Op { get; set; }
    public string Data { get; set; }
}
