Take a value from textbox and insert into an array - Newbie Question!

[rihtx]

Hey everyone,

I am newbie to C# and VS.NET.

I am creating a very small windows application in visual studio 2003. I have single form (form1.cs) that has textboxes for the user to enter the balance, apr and monthly payment for 3 credit cards (9 text boxes).
I would like to create 3 arrays containing the values from each input category. This should be done in a separate class file.
Additional classes file will containing a method that will read the values in the apr array and sort them based on highest APR value, A method that will total calculate the average apr values and the sum of the balance values

How should I apporach this in .net?

Hi, and welcome, ... as you are new to the forums.

Reading your post and especially "This should be done in a separate class file", "A method that will..." makes my think that this is homework or like so (prohibited by the forum rules). Please tell me that i am wrong!

There are many ways to hold data in memory. Eg, in array(s), structs, classes, and/or a combination of them, etc. You choose what best fits you.


Regards.

Tipgiver,

Thanks for quick response. This is an instructor related project. I have carte blanche to create any program as long as I use visual studio. The arrays and methods are not required. I can pass the input values from the user in a console application, but not using visual studio. The methods are not a problem either, just background for you guys to better understand why I chose the arrays in a separate class. This is a debt reduction program.

Anyway all I am trying to do is to pass the input value from the textbox to the array and I have not found any documentation anywhere that specifically addresses this particular issue.

I respect the forum rules so please don't give advice if you feel the forum rules are applying to my post.

I gave you an answer, although i had doubts.
Anyway let's go.

In arrays, you can store data of the same type.

int[] arrayName= new int[2];
arrayName[0] = int.Parse(this.textBox1.Text);
arrayName[1] = int.Parse(this.textBox2.Text);


You said that you have 3 (balance, apr and monthly payment) X 3 textboxes.
You can have 3 arrays of size 3. The 1st will have balance, 2nd the apr and the 3rd the payment.

You can create something like:

struct Card
{
float balance;
int apr;
double payment;
}

and store there the info. (create a 3-dim array of the Card object)

Else, you can create a separate class file with its private variables and write public get/set properties to set and set the private vars.

One correction:

public struct Card
{
public float balance;
public int apr;
public double payment;
}

- The bold are to expose those variables outside the struct, ..so they can be used.
- The blue is just the modifier of the struct. If ommitted, then it will be private.
