That's my CodeBank thread and I provided the very same link to ConnectionStrings.com in that thread. Beginner or not, you should be able to read what the different databases are that they provide examples for and follow the appropriate link, then read through that page and make an attempt at deciding which is the appropriate one.

Now, you're on the right page and you're in the right section so that's good. That connections string means you're logging onto an unnamed instance of SQL Server as the current Windows user on a machine named TSI-CWISTIAN and opening a database named test_ezon. Is that what you want to do? If so then it's correct. Did it work when you tried it? If so then that would also suggest that it's correct. If it didn't work then maybe it's not correct.
