Data storage in program

Question

Hi everyone,

I'm quite new to developing software in C# and would like to know how to store one or more variables that retain on closing the program.

For example I ask a user to enter his name and when I close the program and open it again I can give the commando to show the name again.

Which options does a programmer have to store variables. Is there any good article about this topic?

Thanks!

Answer 1

You either write the data to a file (i suggest you try this first) or you write the data to a database.
Method 1
open a textwriter
write it out
close the textwriter

Answer 2

Look at settings in c#

you can save alle kind of user settings and restoren them at the start.

Answer 3

I agree that storing one variable in a setting is the most easy way to solve this problem. However I would like to see something more in the direction of using Json, XML file or even by using a DLL which will read out on starting up and that can be adjusted when entering a value.
