Have you had experience working with the iterator pattern or similar mechanisms for traversing data collections?

Yes, in C# the iterator pattern is implemented through the interfaces IEnumerable and IEnumerator, which allow traversing a collection sequentially without exposing its internal structure.
For example, you can use a foreach loop to iterate over elements:
List<int> numbers = new List<int> {1, 2, 3, 4};
foreach (int num in numbers)
{
Console.WriteLine(num);
}
You can also implement an iterator yourself using the yield keyword:
public IEnumerable<int> GetNumbers()
{
yield return 1;
yield return 2;
yield return 3;
}
This allows creating lazy sequences and conveniently traversing data.
