Out of memory exception C# List

How should I make a list which can accommodate this range(in the code) since it is showing out of memory exception? 

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var l1 = Enumerable.Range(999900000, 1000000000).ToList();
            l1.ForEach(f => Console.WriteLine(f));
        }
    }
}

Do not collect all data you need in the list especially if you know already the content of it, but use enumerator, to reduce in this way memory footprint of your app.

For example: 

    IEnumerable<int> GetNextInt()
    {
        for(int i=999900000; i< 1000000000; i++)
        {
            yield return i;
        }
    }

and use this after in loop like 

foreach(var integer in GetNextInt())
{ 
    //do something.. 
}

Don't convert to List<T>, just enumerate:

var l1 = Enumerable.Range(999900000, 1000000000);
foreach(var f in l1)
    Console.WriteLine(f);
