HI
how to compare two different list without using for each loop… for ex… Im having two list,
list1(MailMessage) =(“Xxxxx xxxxx@gmail.com”) and
list2(String) =(“Xxxxx xxxxx@gmail.com”)

it should generate output as mail id matched… without using for loop… I already tried by converting list1(MailMessage) to list1(String) and used list1.intersect(list2)… but it didn’t comparing and the count is 0…

I’m not sure if you can do that way, but you can get all the email addresses from your mailmessage list to another list(string)

ListEmail.Add = list1(MailMessage)(1).From.Address ( for each)

and do the intersect
