What is the difference between immutable and mutable types in C#?

What is the difference between immutable and mutable types in C#?

In C#, mutable types can be changed after they are created, while immutable types cannot be modified once initialized.

Can you give me examples of each?

Sure! An example of a mutable type is a List<T>, which allows adding or removing items. An example of an immutable type is string, which cannot be changed after creation.

Why would I use immutable types?

Immutable types are useful for thread safety, easier debugging, and maintaining a consistent state throughout your application.

Are there performance implications when using immutable types?

Yes, while immutable types can lead to safer code, they may incur performance costs due to the need to create new instances instead of modifying existing ones.
