Question

for example

            foreach(var toCheck in query)
            {
                foreach (var againstItem in totalWeight)
                {
                    count1++
                    if (getIEnumerable(toCheck,againstItem).Any(
                           x => { count2++; return (x == againstItem.Key); }))
                    {
                        blacklist.Add(toCheck);
                        break;
                    }
                    count3++;
                }
            }

the results are:
count1 = 166184
count2 = 30620
count3 = 165848

I am expecting count2 would be much bigger compared to count1 and count3

Answer 1

If there are no items to enumerate, the loop will not run and the count2 will not be increased.

Is that possible in your case?
