only return random number when it is unique
- by phil
My brain is melting today and i cannot think how to do this simple bit of code. numberList is a string of numbers seperated by commas like '2, 34, 10' etc.. when i request a random number i need to check if the string has the number, if it does i want to keep requesting a random number until the random number is definitely not in the string. i cant think what kind of loop i would do to get this to work:
Random r = new Random();
public int RandomPos(int max) {
int i;
do {
i = r.Next(max) + 1;
}
while (!numberList.Contains(i.ToString()));
return i;
}
