What are immutable structs in C#?

Immutable structs in C# are data structures that cannot be modified after they are created. This means once you set their values, you cannot change them, which helps in maintaining data integrity.

Can you give me an example of an immutable struct?

Sure! Here's a simple example:

public struct Point
{
    public int X { get; }
    public int Y { get; }

    public Point(int x, int y)
    {
        X = x;
        Y = y;
    }
}

In this example, the Point struct is immutable because its properties can only be set through the constructor.

What are the benefits of using immutable structs?

The benefits include thread safety, easier reasoning about code, and reduced chances of bugs due to unintended modifications.

Are there any downsides to using immutable structs?

Yes, one downside is that every time you want to change an immutable struct, you need to create a new instance, which can lead to performance overhead in certain scenarios.
