How set db and read it?

[namreg]

Hello, I am really a beginner on C# development. But, sometimes i like to play around with C# and try to develop stuff.

I have sql express 2014. Visual C# 2017 Community Version.
I created a database through SQL Management Studio in my local computer.
The name of the DB is ReleasesLogin and has a table called Login and two fields:Login, password.

With C# how do i connect into that DB and populate the the DB ?

Bear with me, i am not 100% proficient with C#. Thanks for your help,

I have created the project already in C#

I suggest that you make use of the tutorial link in my signature below. You should probably read it in its entirety but, specifically, the third-last chapter deals with databases. We can help with specific issues along the way but, to be honest, this question is a bit broad because there are many places that you can learn the basics of data access in C#.

One point to note is that that tutorial suggests creating the data file as part of your project. I would suggest that you just follow the tutorial as written first of all. You can then look at variations, e.g. connecting to Microsoft SQL Server instead of a Microsoft SQL Server Data File. Again, we can help with those specific details but you may gather enough from the tutorial to work through them yourself.
