Question

How do I get the time difference between two DateTime objects using C#?

Answer 1

IF they are both UTC date-time values you can do TimeSpan diff = dateTime1 - dateTime2;

Otherwise your chance of getting the correct answer in every single possible case is zero.

Answer 2

You need to use a TimeSpan. Here is some sample code:

TimeSpan sincelast = TimeSpan.FromTicks(DateTime.Now.Ticks - LastUpdate.Ticks);

Answer 3

private void button1_Click(object sender, EventArgs e)
{
    TimeSpan timespan;
    timespan = dateTimePicker2.Value - dateTimePicker1.Value;
    int timeDifference = timespan.Days;
    MessageBox.Show(timeDifference.ToString());
}
