C # TimeSpan with exceptions

Question

I know this is probably not possible, but someone knows if there are any shortcuts or mechanisms in .NET to allow me to do this.

I have a "Diary"

9AM - 5PM

Inside this diary, I have events or "Assignments"

10AM - 12PM - Destination 1
1pm - 1:30 pm - Destination 2

What I ask is a tool that I can turn over the diary to give me free space outside of these Destinations.

eg. He will return me the list

9AM - 10AM
12PM - 1PM
1:30 pm - 5 pm

So, I can use in my program.

Any ideas?

Answer 3

It seems hard to realize yourself:

• Sort diaries by start date.
• One free period from the start diary> first meeting
• One free period from last appointment> daily diary
• Iterations of assignments and each gap between them - a free period
