long? catCode = null; // Если строка val не пустая, if (!(String.IsNullOrWhiteSpace(val))) { // распознаем в первых цифрах до пробела целое 64-битное число. // Если его там нет, записываем в catCode NULL. // Если его удалось распознать, записываем его в catCode. if (!(Int64.TryParse(val.Split(" ")[0], out long cc))) { catCode = null; } else { catCode = cc; } }
Как переписать этот код чуть понятнее?
⏩Как вариант, можно написать что-то в духе:
public static string LeftDigits(this string str) { if (str == null) return null; if (!str.contains(" ") return null; string left = str.Split(" ")[0]; if (! left.All(Char.IsDigit){ return null; } return left; }

In many cases, the content resembled that of the marketplaces found on the dark web, a group of hidden websites that are popular among hackers and accessed using specific anonymising software.“We have recently been witnessing a 100 per cent-plus rise in Telegram usage by cybercriminals,” said Tal Samra, cyber threat analyst at Cyberint.The rise in nefarious activity comes as users flocked to the encrypted chat app earlier this year after changes to the privacy policy of Facebook-owned rival WhatsApp prompted many to seek out alternatives.
How to Invest in Bitcoin?
Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today?
