What are immutable objects in C# and how do I use them?

Immutable objects in C# are objects whose state cannot be modified after they are created. You can use them to ensure data integrity.

Can you give me an example of an immutable class?

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 class, Name and Age are set only through the constructor and cannot be changed afterward.

What are the benefits of using immutable objects?

Benefits include thread safety, easier debugging, and predictable behavior since the state cannot change unexpectedly.

Are there any downsides to using immutable objects?

Yes, one downside is that they can lead to increased memory usage since a new object is created for each change, rather than modifying an existing one.
