Hey, you can create a generic list of your objects. Loop through both result sets and add them to the list. Let's assume your items are a string :
List<string> myItems = new List<string>();
foreach (string firstListItem in firstCollection)
{
myItems.Add(firstListItem)
}
foreach (string secondListItem in secondCollection)
{
myItems.Add(secondListItem);
}
</string></string>
Then loop trough the entire result and calculate whatever you want :
for (int i = 1; i < myItems.Count; i++)
{
}
Good luck!
