Is there a better way of writing v = (v == 0 ? 1 : 0); [closed]

Answer 1

I would make it more explicit.

What does v mean?

For example when v is some state. Create an object Status. In DDD an value object.

Implement the logic in this value object. Then you can write your code in a more functional way which is more readable. Switching status can be done by creating a new Status based on the current status. Your if statement / logic is then encapsulated in your object, which you can unittest. An valueObject is always immutable, so it has no identity. So for changing it's value you have to create a new one.

Example:

public class Status
{
    private readonly int _actualValue;
    public Status(int value)
    {
        _actualValue = value;
    }
    public Status(Status status)
    {
        _actualValue = status._actualValue == 0 ? 1 : 0; 
    }

    //some equals method to compare two Status objects
}

var status = new Status(0);

Status = new Status(status);
