You use a delegate for method that accepts the result. You can for example use a lambda expression to create that:

Library.getResult(options, result => {
  // code here runs when the result arrives
});

You can also declare a named method:

private void HandleResult(library.libresult<dataCollection> result) {
  //...
}

Then just use its name in the call, which will automatically create a delegate for it:

Library.getResult(options, HandleResult);
