Мы с коллегой только что обнаружили, что, похоже, существует ограничение на количество параметров, которые можно использовать в vb. net code.
Что мне странно, так это то, что этот код будет компилироваться, но когда я его запускаю, он выдает исключение InvalidProgramException, говорящее, что «JIT-компилятор обнаружил внутреннее ограничение».
Кто-нибудь видел что-нибудь подобное раньше? Не могли бы вы указать мне, почему это происходит?
(я использую .net 4.0 с VS 2010. Мы обнаружили это в VS 2008, и результат был немного другим.)
Пример кода:
Dim bigVariable As Double = 10.35
Dim factor As Double = 1.3
Dim hugeNumberOfArgs As Double = (bigVariable * factor) + (bigVariable * factor) +
(bigVariable * factor) + (bigVariable * factor) + (bigVariable * factor) + (bigVariable * factor) + (bigVariable * factor) +
