How do I serialize and deserialize JSON in a Blazor application?

Platform: Blazor| Category: General

JSON (JavaScript Object Notation) is a lightweight data-interchange format and a text format that is language independent. In Blazor, the JsonSerializer class, found in the System.Text.Json namespace, assists with serializing and deserializing JSON data.

@code {
    public class User
        public int ID { get; set; } 
        public string? Name { get; set; } 
        public string? Address { get; set; } 
    User user = new User() { ID = 1, Name = "Manas", Address = "India" }; 
    public string? serializedString { get; set; } 
    void SerializeMethod () 
        //for serialization 
        serializedString = System.Text.Json.JsonSerializer.Serialize(user); 

    void DeserializeMethod () 
        //for deserialization 
        User userCopy = System.Text.Json.JsonSerializer.Deserialize<User>(serializedString); 

In the provided sample, JsonSerialize.Serialize(object) is used to serialize the user object of the User class into a string. Then, JsonSerialize.Deserialize<ClassName>(JsonObject) is used to deserialize the serializedString string into a new instance of the User class named userCopy
