See this code as an example:

C#

private void Form1_Load(object sender, EventArgs e)
{
  DateTime tm1 = DateTime.Parse("08:30:00");
  DateTime tm2 = DateTime.Parse("17:15:00");
  TimeSpan span = tm2 - tm1;
  MessageBox.Show(span.ToString());
}

Try this:

C#

protected void Page_Load(object sender, EventArgs e)
{
    // Declare and get DateTime values
    DateTime StartDate = System.DateTime.Now;
    DateTime EndDate = System.DateTime.UtcNow;
 
    // Find time difference between two dates
    TimeSpan TimeDifference = StartDate - EndDate;
 
    // Write difference in hours and minutes
    Response.Write("Time difference between server time and Coordinated Universal Time (UTC) is " +
        TimeDifference.Hours.ToString() + " hours ");
    if (TimeDifference.Minutes != 0)
        Response.Write(" and " + TimeDifference.Minutes.ToString() + " minutes.");
 
}

Hi.
Try this:

C#

DateTime dt1 = new DateTime((long)TimeSpan.FromMinutes(30).TotalMilliseconds);
			DateTime dt2 = new DateTime((long)TimeSpan.FromMinutes(29).TotalMilliseconds);

			TimeSpan diff = dt1 - dt2;

Solution 5

C#

DateTime dt1= DateTime.Parse("08:30:00");
DateTime dt2= DateTime.Parse("17:15:00");
TimeSpan span = dt2- dt1;

or

C#

DateTime dt1= DateTime.Parse("08:30:00");
DateTime dt2= DateTime.Parse("17:15:00");
string span = (dt2- dt1).Hours+":"+(dt2- dt1).Minutes;

Try this

C#

DateTime time1 = DateTime.ParseExact("08:30:00", "HH:mm:ss", System.Globalization.CultureInfo.InvariantCulture);

DateTime time2 = DateTime.ParseExact("17:15:00", "HH:mm:ss", System.Globalization.CultureInfo.InvariantCulture);

TimeSpan diff = time2 - time1;

OR

C#

DateTime time1 = DateTime.Parse("08:30:00");
DateTime time2 = DateTime.Parse("17:15:00");
TimeSpan diff = time2 - time1;
