asp.net database connection integrates the previous PHP database connection class~~ to make a paging class!

I don’t know if there is any future for learning PHP~ Hey, the more I write, the more boring I feel.

This class has been debugged! It is very easy to use~~~~~~~~~~~~~~~~~
The class is your knife~If you don’t refine it in advance, it will be difficult to use it. Go to practice when you fight! ~ Early death ~~
All I have time! Write a functional category ~~~~~~
I should say this category ~~ It's relatively simple ~~~ Look If you don’t understand, ask~
