xamarin 的初学者。我想在不添加秒数的情况下将时间显示为 HH:mm。它在我的表单上显示为示例 12:30:00，我只想显示为 12:30。我是否需要更改日期时间函数，代码当前正在运行，但仍将时间显示为时分秒。
代码还应该允许最快的时间出现在顶部，但它似乎也没有这样做。
void FindNextDue(ObservableCollection<UserMedDosagePayLoad> medtimes)
{
UserMedTimesFilteredList.Clear();
int nowHour = DateTime.Now.Hour;
int nowMinutes = DateTime.Now.Minute;
TimeSpan now = new TimeSpan(nowHour, nowMinutes, 0);
foreach (UserMedDosagePayLoad item in medtimes)
{
item.Nextduemessage = item.Dosage + " " + item.Dosageunit +
"due at " + item.Time;
string[] DT = item.Time.Split(':');
if (DT[0] != null)
{
int hr = Convert.ToInt32(DT[0]);
int minutes = Convert.ToInt32(DT[1]);
TimeSpan medTime = new TimeSpan(hr, minutes, 0);
TimeSpan comparison = now.Subtract(medTime).Negate();
TimeSpan TwentyFourHour = new TimeSpan(24, 0, 0);
if (comparison.TotalMilliseconds <0)
{
comparison = TwentyFourHour.Add(comparison);
}
TimeComparison.Add(comparison);
}
}
//Order the collection of times so the next due is always first
TimeComparison = new List<TimeSpan>(TimeComparison.OrderBy(h => h.Hours)
.ThenBy(m => m.Minutes));
List<string> UserMedIDs = new List<string>();
for (int i = 0; i < TimeComparison.Count(); i++)
{
DateTime NextDue = DateTime.Now.Add(TimeComparison[i]);
DateTime NextDueToCompare = new DateTime(NextDue.Year, NextDue.Month,
NextDue.Day, NextDue.Hour, NextDue.Minute, 0);
string NextDueComparisonString = NextDueToCompare.ToString("HH:mm:ss");
foreach (UserMedDosagePayLoad item in UserMedTimes)
{
if (item.Time == NextDueComparisonString &&
!UserMedIDs.Contains(item.Usermedid))
{
UserMedTimesFilteredList.Add(item);
UserMedIDs.Add(item.Usermedid);
}
}
UserMedTimes = medtimes;
MedicationList.ItemsSource = UserMedTimesFilteredList;
BusyIndicator.IsRunning = false;
