DateTime eventDate = DateTime.Now;

Console.WriteLine($"{eventDate.Year}年{eventDate.Month}月{eventDate.Day}日 {eventDate.Hour.ToString().PadLeft(2,‘0’)}:{eventDate.Minute.ToString().PadLeft(2,‘0’)}:{eventDate.Second.ToString().PadLeft(2,‘0’)}");

DateTime eventDate = DateTime.Now;
Console.WriteLine($"{eventDate.Year}年{eventDate.Month}月{eventDate.Day}日 {eventDate.Hour.ToString().PadLeft(2,'0')}:{eventDate.Minute.ToString().PadLeft(2,'0')}:{eventDate.Second.ToString().PadLeft(2,'0')}");
