Question

In C#, given the two methods

 bool Action1(object Data);
bool Action2(object Data);

that are used in an if statement like this:

if ( Action1(Data) || (Action2(Data) )
{
    PerformOtherAction();
}

will Action2() still be called if Action1() returned true, or is this prevented by compiler optimisation, since it is already known that the expression will evaluate to true?

Answer 1

Action2() will only be called if Action1() returns false

This is conceptually similar to

if (Action1(Data))
{
    PerformOtherAction();
} 
else if (Action2(Data))
{
    PerformOtherAction();
}
