    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?

    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.
