random numbers in array check they don't repeat

I have an array of variable length that either the user can enter a set of numbers between 1 and 9 or get a random set of numbers between 1 and 9. I need to make sure that either way the numbers do not repeat. I know I need a loop just not sure which one I should use. I will post the code I have for the user entering their own set of numbers as the first comment if that helps any.

Here you go. You can't try it here on playground. You have to do it on your computer. https://code.sololearn.com/cmkIvyJtdwcz/?ref=app

for(int aaa = 0; aaa < 4; aaa++) { Console.Write("Pick a number between 1 and 9, numbers cannot repeat : "); string playernum = Console.ReadLine(); while (!int.TryParse(playernum, out playerNum[aaa]) & playerNum[aaa] < 1 | playerNum[aaa] > 9 ) { Console.Write("You must enter a number between 1 and 9, numbers cannot repeat : "); playernum = Console.ReadLine(); } }
