C# / .NET - generate set with 10 random unique numbers

Random.Next method + HashSet<T> class example

public static class RandomUtils
{
	public static HashSet<int> generateSet(int count)
	{
		Random random = new Random();
		HashSet<int> values = new HashSet<int>();

		for (int i = 0; i < count;)
		{
			int value = random.Next();

			if (values.Add(value))
				i += 1;
		}

		return values;
	}
}

Example:

HashSet<int> values = RandomUtils.generateSet(10);

foreach (int entry in values)
	Console.WriteLine(entry);

Output:
