Generating random, unique values C#

Question

I\'ve searched for a while and been struggling to find this, I\'m trying to generate several random, unique numbers is C#. I\'m using System.Random, and I\'m us

Answer 1

Same as @Habib's answer, but as a function:

List randomList = new List();
int UniqueRandomInt(int min, int max)
{
    var rand = new Random();
    int myNumber;
    do
    {
       myNumber = rand.Next(min, max);
    } while (randomList.Contains(myNumber));
    return myNumber;
}

If randomList is a class property, UniqueRandomInt will return unique integers in the context of the same instance of that class. If you want it to be unique globally, you will need to make randomList static.
