What are some examples of immutable types in C#?

In C#, immutable types are types whose instances cannot be modified after they are created. Examples include the string class, DateTime, and custom structs defined with read-only properties.

Can you explain why immutability is important?

Immutability is important because it helps to ensure thread safety, reduces bugs related to state changes, and makes it easier to reason about code.

How do I create an immutable class in C#?

To create an immutable class in C#, define all properties as read-only and set their values through a constructor. 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;
    }
}
