Dear Axay,
We do not have a magic ball, how can we help you if you do not supply any code or example? Should we try to guess how your code is working? Or you do not know how to create a string from multiple strings???
If that is what you are trying to achieve here is a sample:
String.Join(String.Empty, messagesArray);
It is not the most performant way but it will work.
Cheers
