Select and insert multiple row values from a listview to a database

I'm having a dilemma about my code, I want to select multiple values from a ListView, example table:

Number-|Name------|Surname

1---------|Travis------|Stever

2---------|Claudio----|Sanchez

3---------|Wes--------|Styles

Like so. I want my ListView to be able to select multiple rows, so in my example I'll select Travis and Wes only, and when I click a button I should be able to insert into a database the Number 1 and 3 only.

Any snippet would be leaps of help for me. Thank you in advance.
