Best use of arrays

Best use of arrays

Hi

I have justed signed up because this seems to deal with c#.

I am using visual Studio 17 & c# and writing my own 'practice programs'

I have read many different responses to 'global arrays' and understand not the bestt way to go.

IF I have a banking data file with:-

Date DateofT
StringT Text of transaction - CCARD PAYMENT TO ASDA SUPERSTORE.....ETC
Double ValueIN = monies paid IN
Double ValueOUT = monies paid OUT

How would I best define / declare / structure this data rather than using a mult- dimensional globle type array.

I'd wish to read data into the above in one routine - say - i.e. hit Button to Read Data from File

I'd wish to interrogate data:-

all transcation between date 1 and date 2
all transactions contain ASDA
write my data to a listbox
from the listbox - to printer or file if required

sort of think mydata.DateofT, mydata.StringT etc with the nth item in each list being all part of the same initial line of data.

Hope this makes sense. My project starts like this

namespace MyTestingDesktop
{
public partial class MyTestingDesktop : Form
{
public MyTestingDesktop()
{
InitializeComponent();
}

Any guidance really appreciated

Hi.
Inplace of storing the data in array, i would say you should create a class and in that class, create some properties like DateofT,ValueIN etc.After that you create the Object of class and in those properties you can store the data.Even if you can apply abstraction,encapsulation etc all those concepts because as you said this application belongs to a banking data and banking data should be secure.
