将CString日期键转换为长键

#include <iostream>
#include <ctime>

long long convertCStringToLongKey(const char* cStringDate) {
    // 解析字符串日期键
    struct std::tm tm;
    strptime(cStringDate, "%Y-%m-%d", &tm);

    // 转换为长整型键
    std::time_t time = std::mktime(&tm);
    return static_cast<long long>(time);
}

int main() {
    const char* cStringDate = "2022-01-01";
    long long longKey = convertCStringToLongKey(cStringDate);
    std::cout << "Long key: " << longKey << std::endl;

    return 0;
}
