Hei. Stavo leggendo la fonte decompilata di Digi Traffic Accelerator (penso che sia il modo migliore per imparare), finché non ho ottenuto un codice non comprensibile! Si prega di dare un'occhiata:Comprensione del tipo generato dal compilatore in dotPeek del codice decompilato

Come si può vedere, sembra in CheckProxy metodo, il compilatore ha generato un nuovo tipo! Hai idea di cosa stia realmente succedendo in questo metodo? Come posso capire il codice?
Questa è una carenza di decompilatore, segnalarla. – usr
