[英]How to assign a time value from a textbox to a variable?
我试图弄清楚如何将文本框中的小时,分钟,秒和毫秒值设置为长变量,以便可以在应用程序中操作时间值。
到目前为止,我一直在尝试创建一个名为“ workTime”的长变量,但是我不确定如何将在文本框中输入的值分配为一段时间。
例如,如果用户输入“ 00:02:30:000”,我该如何将其分配给变量?
是否可以通过这种方式分配时间值?
任何建议或替代方法将不胜感激。
private void startBtn_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
string wrkString;
string rstString;
int i;
//Assign text box time string to string variables.
wrkString = wrkTbx.Text;
rstString = restTbx.Text;
//Assign text box string value to a date time variable.
DateTime workDt = DateTime.ParseExact(wrkString.Replace(": ", ":").Replace(" :", ":"), "HH:mm:ss:fff", CultureInfo.InvariantCulture);
DateTime restDt = DateTime.ParseExact(rstString.Replace(": ", ":").Replace(" :", ":"), "HH:mm:ss:fff", CultureInfo.InvariantCulture);
StopGoCvs.Background = new SolidColorBrush(Colors.Green);
hornElmt.Play();
// // set up the timer
myTimer = new DispatcherTimer();
myTimer.Interval = new TimeSpan(0, 0, 0, 0, 1);
myTimer.Tick += myTimer_Tick;
//tell timer to stop when it has reached the allocated work time.
if(myTimer.Interval != workDt.TimeOfDay)
{
// start both timers
myTimer.Start();
myStopwatch.Start();
}
else
{
myTimer.Stop();
myStopwatch.Stop();
}
}
尝试这个:
DateTime dt = DateTime.ParseExact(time.Replace(": ", ":").Replace(" :", ":"), "HH:mm:ss:fff", CultureInfo.InvariantCulture);
//using System.Globalization
TimeSpan.ParseExact("00 : 02 : 30 : 000", @"%h\ \:\ %m\ \:\ %s\ \:\ %fff", CultureInfo.InvariantCulture.DateTimeFormat)
//from here you can decide to store the timespan value or the miliseconds via its 'TotalMilliseconds' property.
//It may help with readability by removing the space from the input
TimeSpan.ParseExact("00 : 02 : 30 : 000".Replace(" ", ""), @"%h\:%m\:%s\:%fff", System.Globalization.CultureInfo.InvariantCulture.DateTimeFormat)
