Create different/unique random numbers in C#
After I’ve shown you (in this post) how to generate unique random numbers in PHP, I’ll show you now how to do the same thing in C#. If you’re wondering, for what you need different unique random numbers, you really should have a gander at the PHP-based article. Otherwise go on and take a look at the following snippet.
//Define the range of random numbers, from which
//the routine should choose
int smallestNumber = 1;
int biggestNumber = 10;
//Determine the amount of random numbers
int amountOfRandomNumbers = 5;
//Create a list of numbers from which the routine
//shall choose the result numbers
List possibleNumbers = new List();
for (int i = smallestNumber; i <= biggestNumber; i++)
possibleNumbers.Add(i);
//Create a list, which shall hold the result numbers
List resultList = new List();
//Initialize a random number generator
Random rand = new Random();
//For-loop which picks each round a unique random number
for (int i = 0; i < amountOfRandomNumbers; i++)
