Hi!
Yes, that is all possible. Using an anonymous class as in your example:
.Select(res => new
{
Combination = res.Week + res.Year,
Substring = res.Year.Substring(0, 2)
});
Or if you want a simple list of strings:
.Select(res => res.Year.Substring(0, 2))
or
.Select(res => res.Week + ", " + res.Year)
