How to use database in c# application?

Question

Should I learn sql (but how to retrieve data in c# app etc?), maybe LINQ or are there other options?
And which database is the best for start, mySql, mirosoft sql server, postgresql, nosql?

Answer 1

Agree, mySql is a good option to start.

use a SqlConnection to connect to the database
use a SqlCommand to define your request "select * from tableX"
and a SqlDataReader to read the data

Answer 2

mySql would be a better option to start.....
