Time Difference Calculation in Asp.net

Question

0.00/5 (No votes)

See more:

I created an ajax timer in a asp.net page. It's showing current time, in the short time format (9:33 AM) and its running.

When I clicked on a button, current clock time displays on a textbox, and on another button click the current time displays in another textbox.

For example if the value in the first textbox is 9:23 and second textbox is 9:30; How can I calculate the time difference?

9:30 - 9:23 = 0:07

Help me to find the time difference.

The structure System.DateTime has "-" (subtraction operator) defined, return type is System.TimeSpan.

See http://msdn.microsoft.com/en-us/library/system.datetime.aspx[^].

This should be more then enough.

Solution 1

Hi,

MSIL

DateTime dateTime1 = Convert.ToDateTime("9:30");
DateTime dateTime2 = Convert.ToDateTime("9:23");
TimeSpan timeSpan=dateTime1.Subtract(dateTime2);

Note: As the time string don't have AM or PM the conversion will take it as a 24 hr clock
