Do nothing when “other side” of ternary operator is reached?

Question

Note: I\'ve seen this question asked sometimes before (a, b, c), but neither of these was in C#, nor helpful.

Assume I\'m using the ? : ternary

Answer 1

I can suggest an extension method like this:

public static T ChangeOn(this T variable, bool condition, T newValue)
{
    return condition ? newValue : variable;
}

And use it like this:

var result = r.ChangeOn(r == 5, 0);
//or: r = r.ChangeOn(r == 5, 0); for self change
