C# Immutable Classes vs Mutable Classes

What are the main differences between immutable and mutable classes in C#?

Immutable classes cannot be changed after they are created, while mutable classes can be modified. This affects how you manage state.

Can you give me an example of an immutable class in C#?

Sure! Here's a simple example:

public class Person
{
    public string Name { get; }
    public int Age { get; }

    public Person(string name, int age)
    {
        Name = name;
        Age = age;
    }
}

In this example, once a Person object is created, its Name and Age cannot be changed.

What are the benefits of using immutable classes?

Immutable classes are thread-safe, easier to reason about, and can help prevent bugs related to unintended changes.

Are there any downsides to using immutable classes?

Yes, they can lead to increased memory usage and may require more complex code for operations that involve changing state.
