Is there inifinite list in c#? [closed]

Question

I want to find Haskell's analogue of infinite list in c# language. I want to use any possible interfaces for such list, like these:

IEnumerable

ICollection

IList

Answer 1

I found an article on the subject here.

Essentially you can utilize the yield keyword to programmatically create the next element of your list.

Answer 2

Using IEnumerable and yield return you can easily create infinite sets.

static IEnumerable<uint> UpDown(uint min = uint.MinValue, uint max = uint.MaxValue, uint step = 1)
{
    if (min > max)
        throw new ArgumentOutOfRangeException("min", "'min' must be less than or equal to 'max'");
    var current = min;
    var last = current;
    var up = true;
    while (true)
    {
        yield return current;
        current += (uint)(up ? step : -step);
        if (up && (current >= max || current < last))
        {
            up = !up;
            current = max;
        }
        else if (!up && (current <= min || current > last))
        {
            up = !up;
            current = min;
        }
        last = current;
    }
}

static IEnumerable<int> Random()
{
    while (true)
        yield return 4;
}

Answer 3

The type that most closely corresponds to a lazy Haskell-like list, is IEnumerable<out T>.
