Is the return value used?

Question

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
