29.7 How do I determine the time taken for a long operation that I perform? |
You could use the DateTime.Ticks property to record the time taken for a long operation, as follows: |
|
|
| [C#]
|
| private void MyLongOp()
|
| {
|
| long startTicks = DateTime.Now.Ticks;
|
|
|
| // Perform a long op:
|
|
|
| long endTicks = DateTime.Now.Ticks;
|
|
|
| long delta = endTicks - startTicks;
|
| MessageBox.Show("Time taken in Ticks: " + delta.ToString());
|
| delta = delta/(long)10000000; // A tick is 100 nanoseconds
|
| MessageBox.Show("Time taken in seconds: " + delta.ToString());
|
| }
|
|
|
|
| [VB.Net]
|
| Private Sub MyLongOp()
|
| Dim startTicks As Long = DateTime.Now.Ticks
|
|
|
| ' Perform a long op:
|
|
|
| Dim endTicks As Long = DateTime.Now.Ticks
|
|
|
| Dim delta As Long = endTicks - startTicks
|
| MessageBox.Show("Time taken in Ticks: " + delta.ToString())
|
| delta = delta/(Long)10000000 ' A tick is 100 nanoseconds
|
| MessageBox.Show("Time taken in seconds: " + delta.ToString())
|
| End Sub
|
