TimeSpan Problem

Why is it that:

DateTime start = DateTime.Parse("1:00 AM");
DateTime stop = DateTime.Parse("2:30 AM");
TimeSpan ts = stop - start;
Response.Write(ts.Minutes.ToString());

Produces 30, not 90? How do I return the exact number of minutes between 2
times?

Thanks a lot.

Because the number of minutes on the resulting TimeSpan is 30. If you
want to get the total number of minutes, you need to access the TotalMinutes
property.

What you need is ts.TotalMinutes

Because the Minutes property of the TimeSpan struct represents the
minutes in the hour, not the total number of minutes. Just use the
TotalMinutes property.

Hi,

Take a look at TotalMinutes

Perfect. Didn't even notice TotalMinutes. Thanks a lot.

Hi All,
I have a problem with TimeSpan when I want to compute and compare the time duration of two tasks or more. So I tried with simple code to make sure the problem is with TimeSpan. Here my codes are.....

static void Main(string[] args)
{
long total = 0;

DateTime startTime1 = DateTime.Now;

for (int count = 0; count < 100; count++)
{
total += count;
}

DateTime stopTime1 = DateTime.Now;

/* Compute and print the duration of the first task. */
TimeSpan duration1 = stopTime1 - startTime1;
Console.WriteLine("First task duration: {0} milliseconds.", duration1.TotalMilliseconds);

/* Now I want to measure another task which has more duration time. */
DateTime startTime2 = DateTime.Now;

for (int count = 0; count < 10000; count++)
{
total += count;
}

DateTime stopTime2 = DateTime.Now;

/* Compute and print the duration of this second task. */
TimeSpan duration2 = stopTime2 - startTime2;
Console.WriteLine("Second task duration: {0} milliseconds.", duration2.TotalMilliseconds);


}


When I run it, the result was shown

First task duration : 4 milliseconds.
Second task duration : 0 milliseconds.
Press any key to continue...............

I don't understand why it happened. When I used the code Thread.Sleep(1200) in the place of for loop count at second tasks, TimeSpan worked correctly. Please give me some solution for that problem.

Thank you all in advance.
