Suppose I have a list or array of items, and I want to sum a subset of the items in the list. (in my case, it happens to always be a sequential subset).

Here's the old-fashioned way:


int sum = 0;
for(int i = startIndex; i <= stopIndex; i++)
  sum += myList[i].TheValue;
return sum;

What's the best way to linqify that code?
