How to calculate the difference between two times in C #. Calculate the difference between 2 times, you can calculate the time seconds!
| The code is as follows |
Copy Code |
| <1>
Label1. Text = "2004-1-1 15:36:05″;
Label2. Text = "2004-3-1 20:16:35″;
DateTime d1 =new datetime (2004,1,1,15,36,05);
DateTime d2 =new datetime (2004,3,1,20,16,35);
TimeSpan D3 = D2. Subtract (D1);
Label3. Text = "Difference:"
+d3. Days.tostring () + "Days"
+d3. Hours.tostring () + "hours"
+d3. Minutes.tostring () + "minutes"
+d3. Seconds.tostring () + "seconds"; <2>
protected void Page_Load (object sender, EventArgs e)
{
if (! IsPostBack)
{
DateTime dt1 = Convert.todatetime ("2009-07-31 00:00:00″");
DateTime DT2 = Convert.todatetime ("2009-08-02 00:00:00″");
This. Label1.Text = this. DateDiff (DT1,DT2);
}
}
private String DateDiff (DateTime DateTime1, datetime DateTime2)
{
string dateDiff = null;
Try
{
TimeSpan ts1 = new TimeSpan (datetime1.ticks);
TimeSpan ts2 = new TimeSpan (datetime2.ticks);
TimeSpan ts = ts1. Subtract (TS2). Duration ();
DateDiff = ts. Days.tostring () + "days" + TS. Hours.tostring () + "hour" + TS. Minutes.tostring () + "minutes" + TS. Seconds.tostring () + "seconds";
}
Catch
{ }
return DateDiff;
}
<3>
String st1 = "14:16″;"
String st2 = "14:14″;"
DateTime dt1 = Convert.todatetime (ST1);
DateTime DT2 = Convert.todatetime (ST2); int result = Datetime.compare (DT1, DT2); |
If the st1 time is greater than st2 , result = 1
If equal equals 0,
if less than-1
