strange method

Question

Hello I am learning C# from a boo k and now I tried to build a search app with that book. And i tried to run it and I can't because there is something wrong with the method: GetMaxPossibleDestinationsArraySize() , I have tried to search it on msdn.com
but there was no result. Does somebody know if this Method really exists or is it written in another way or something? I have also looked on google, but without result.

thanks keffie91
