Introduction
Usually, we create custom classes to store the deserialized data from json. These custom classes were no more required if we use dynamic type which is introduced in C# 4.0.
Using the Code
Usual way of deserializing json using Newtonsoft:
class Car
{
public string Name;
public string Company;
public int Id;
}
class Program
{
static void Main(string[] args)
{
Car car = new Car() { Id = 1, Name = "Polo", Company = "VW" };
string serialized = JsonConvert.SerializeObject(car);
Car deserialized= JsonConvert.DeserializeObject<Car>(serialized);
Console.WriteLine(deserialized.Company + " " + deserialized.Name);
Console.ReadLine();
}
}
New way using dynamic:
class Program
{
static void Main(string[] args)
{
Car car = new Car() { Id = 1, Name = "Polo", Company = "VW" };
string serialized = JsonConvert.SerializeObject(car);
dynamic deserialized = JsonConvert.DeserializeObject(serialized);
Console.WriteLine(deserialized.Company + " " + deserialized.Name);
Console.ReadLine();
}
}
As dynamic type skips the compile time binding and performs the binding dynamically, intellisense support will not be available,
Also, if you try to access a non-existant property like deserialized.Price
which is not in the json, it will throw neither compile time or run time error. It will be considered as null
and no code break.
