Just like IEnumerable.Where(predicate).Last() should be optimized to IEnumerable.Last(predicate), Sum() and other methods that include selectors should be optimized:
The example above is slightly more complex than a straightforward conversion because int.Parse() cannot be used directly and must be used as lambda expression.
static int Sum(IEnumerable<string> vals)
{
return vals.Select(int.Parse).Sum(); // Should be converted to: vals.Sum(i => int.Parse(i));
}
