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; }

Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised. While no messaging app can guarantee a 100% impermeable defense against determined attackers, Telegram is vulnerabilities are few and either theoretical or based on spoof files fooling users into actively enabling an attack.
How to Buy Bitcoin?
Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
