Which part do you need help with:
- Declaring a 15-element array?
- Generating a random number?
- Ensuring that the number is not already in the array?

ensuring that the number is not already in the array.

I would probably use a Hashtable (System.Collections namespace). You can use the .Contains method to determine whether a value is already present and the .CopyTo method to copy it to an array when you have 15 unique values.
