Is the return value used?

Poul Christiansen

I have a method lik ethis:
public bool DoSomething()
{
....
}

It is possible to use this method like this:
if (DoSomething())
....

or like this
DoSomething();

Is there anyway that I can, within the DoSomething method, figure out from reflection or somewhere else if the return value is used by the calling code?

Any help is much appreciated?

Best regards

It's certainly possible to call it like this:

if (DoSomething())

It's also possible to call it like this but if you do so then the bool return value will be discarded:

DoSomething();

However, there's no way that you can figure out within the DoSomething() method whether it's return value is used by the calling code or not.
