Amendment to DNRTV Episode Part 3

After I finished up recording part 3. I realized that I was not showing off as many ReSharper shortcuts as I could have. That will definitely change over the course of the next set of episodes. For the remainder of the series I will be recording the entire series 'sans mouse'. Hopefully this will give people an idea of how productive you can actually be without using the keyboard mouse. As soon as I had finished recording the session I thought to myself 'yikes, I made that list enumerable way more complicated that it should have been'. Instead of this:
public class ListEnumerable<T> : IEnumerable<T>
{
private IList<T> itemsToEnumerate;
public ListEnumerable(IList<T> itemsToEnumerate)
{
this.itemsToEnumerate = itemsToEnumerate;
}
public IEnumerator<T> GetEnumerator()
{
return new ListEnumerator<T>(itemsToEnumerate);
}
IEnumerator IEnumerable.GetEnumerator()
{
return new ListEnumerator<T>(itemsToEnumerate);
}
}
I could have simply done this:
public class ListEnumerable<T> : IEnumerable<T>
{
private IList<T> itemsToEnumerate;
public ListEnumerable(IList<T> itemsToEnumerate)
{
this.itemsToEnumerate = itemsToEnumerate;
}
public IEnumerator<T> GetEnumerator()
{
return itemsToEnumerate.GetEnumerator();
}
IEnumerator IEnumerable.GetEnumerator()
{
return itemsToEnumerate.GetEnumerator();
}
}
And of course, an even easier way (if you have .Net 2.0) is to just leverage the yield keyword inside of a method returning IEnumerable. Which is how I started off the discussion on iterators.
