This is not very advanced.

1. Get the selected values from each dropdown box.

2. If the values are strings, you need to convert them to the data type DateTime, see DateTime.TryParse[^]

3. Then you subtract the two DateTime variables.
The result will be an object of type TimeSpan[^].

4. Store the value in a suitable table in your database
See SQL Insert[^]

5. You will also need a database connection[^] and a SQL command[^]

That should do it, I think.

Solution 2

1. Get the time difference like this-

C#

TimeSpan time1 = TimeSpan.Parse(dropdown1.SelectedItem); // can't recall the actual property to get the selected item text :laugh:
TimeSpan time2 = TimeSpan.Parse(dropdown2.SelectedItem);
TimeSpan difference = time1 - time2;
int hours = difference.Hours;
int minutes = difference.Minutes;

2. Use the SQL Insert[^] statement to store the appropriate value in database. Refer this tutorial[^] for more idea.

Don't you mean
DateTime time1 = DateTime.Parse(dropdown1.SelectedItem);
?

But 8:30PM is not an interval. Right?
