How can I serialize collections in C#?

How can I serialize collections in C#?

You can serialize collections in C# using the JsonSerializer class from the System.Text.Json namespace.

Can you show me an example of serializing a list?

Sure! Here's a simple example:

using System;
using System.Collections.Generic;
using System.Text.Json;

class Program
{
    static void Main()
    {
        var list = new List<string> { "apple", "banana", "cherry" };
        string json = JsonSerializer.Serialize(list);
        Console.WriteLine(json);
    }
}

What about deserializing it back to a list?

To deserialize, you can use JsonSerializer.Deserialize<T>(). Here's how:

var json = "[\"apple\", \"banana\", \"cherry\"]";
var list = JsonSerializer.Deserialize<List<string>>(json);

Are there any other serialization formats I can use?

Yes, you can also use XML serialization with XmlSerializer or binary serialization with BinaryFormatter, depending on your needs.
