Вот мой код для справки. Если вы перейдете в раздел «SYSCALL», вы найдете инструкцию if, относящуюся к «открытому 4», где я застрял. О, кстати, я не использую визуальную студию, я использую программу под названием «Verilator», которая позволяет мне связывать Verilog Code с кодом C++.

Есть ли какой-нибудь файл, который нужно включить, чтобы использовать var и byte? Извините, я новичок. –
, пожалуйста, не включайте теги (C#) в заголовок. Оставьте их в тегах. Также, пожалуйста, разместите код, и если вы получаете ошибку компиляции, покажите ошибку и скажите, какую версию Visual Studio вы используете. –
Когда я использую идею Грега, var chars = DataMemory.Skip (top-> a0) .TakeWhile (i => i! = 0). Выберите (i => (char) i); var str = новая строка (chars.ToArray()); Я получаю ошибки, говоря, что var не был объявлен. –
