使用date.Hour C＃进行登录和注销的更正检测

如何解决使用date.Hour C＃进行登录和注销的更正检测

在设置aftternoon登录时间时遇到问题，该时间应为12:31 pm至4:59 pm

当我尝试使用下午登录名更改时间时，它会给我not recorded else语句

DateTime date = DateTime.Now;

// 0:00 to 11:59
if (date.Hour >= 0 && date.Hour <= 11) {
    MessageBox.Show("Morning Login");
}
// 12:00 between 0 minutes and 30
else if (date.Hour == 12 && date.Minute >= 0 && date.Minute <= 30) {
    MessageBox.Show("Morning logout");
}
// This is the condition I'm having problems with
else if (date.Hour == 12 || date.Hour >= 13 && date.Hour <= 16) {
    // I'm setting the time to afternoon login that should be 12:31pm to 4:59pm
    MessageBox.Show("Afternoon Login");
}
else if (date.Hour >= 17 && date.Hour <= 23)
{
    MessageBox.Show("Afternoon logout");
}
else
{
    MessageBox.Show("Not recorded");
}

解决方法

正如Panagiotis在评论中建议的那样，您应该使用TimeSpan进行比较

您的下午检查条件可能是

else if ((date.TimeOfDay >= new TimeSpan(12,31,0)) && (date.TimeOfDay <= new TimeSpan(16,59,0)))
{
   MessageBox.Show("Afternoon Login");
}
