如何将字符串转换为时间字符串 C#

Question

How can I convert the following

string Time = "2324"; string Time = "1024";

In the first case the converted value should be another string "11:24 PM". The second case should be "10:24 AM".

I tried Date.ParseExact(Time,"hh:mm tt",CultureInfo.InvariantCulture) That solves it when the time is less than 12:00PM. But when it is "2324", I get 23:24 PM when I actually need 11:24 PM

Answer 1

Method expects time to be always 4 characters

    static string ParseTime(string time)
    {
        if (int.TryParse(time.Substring(0, 2), out int hrs) && int.TryParse(time.Substring(2), out int min))
        {
            return new DateTime(2001, 1, 1, hrs, min, 0).ToString("hh:mm tt", CultureInfo.InvariantCulture);
        }
        // throw exception or return empty;
        return string.Empty;
    }
