Question

Does C# have something like the JavaScript if or value syntax?

For example, I know you can do this in JavaScript:

var test = someValue || thisValue;

if someValue is undefined, false, or empty string, then test becomes thisValue. However, I’ve never seen a way to do this in C# other than a traditional if, or inline if.

Answer 1

NullCoalesce

var test = someValue ?? thisValue;

However, C# doesn’t do weird JavaScript falsey behaviors.

The short circuit evaluation in C# is more pertinent in evaulating bools:

private bool EvaluateA()
{
    return true;
}

private bool EvaluateB()
{
    return false;
}

public static int main()
{
    Console.Write(EvaluateA() || EvaluateB()); // EvaluateB is never called
}
