Using related data stored in a 2 dimensional array

The key lies in the fact that the data is related. Rather than breaking up your “car” into pieces to store in different arrays, a Class would allow you to create a Car object, and store various cars in a typed List:

Five Minute Intro to Classes and Lists

Public Class Car
    Public Property Id As Int32
    Public Property Make As String
    Public Property Model As String
    Public Property Year As Int32
    '... etc
End Class

Now you have a container to save all the info for one car. This is like a blueprint for what a Car object will look like. A Class can also contain methods (Sub or Function) to manage the data they store so that everything relating to a Car or Employee or Order can be managed by that class.

Dim c As New Car          ' create a new car object
c.Make = "Mazda"
c.Model = "Miata"
c.Year = 2013

Or initialize when you declare it:

Dim c As New Car With {.Make = "Mazda", .Model = "Miata" ...}

Now, the New Millennium version of arrays, is a List. These are much easier to work with because they size themselves:

Dim Cars As New List(Of Car)

The Cars collection can only store car objects, each car it stores keeps the data together for each one. There are many other collection types such as Dictionary you will eventually want to get familiar with. Add the Mazda to the List:

' c is the car object created above
Cars.Add(c)

Unlike arrays there is no need to know how many cars you will be working with because they resize themselves. To reference one, Cars(n) will refer to a car object:

' n is the index of a car in the list
Dim str = Cars(n).Make & " is " & Cars(n).Color

Iterate the list, using a temp Car variable:

For Each c As Car In Cars   
    ' c will be Cars(0), Cars(1) etc as we step thru
    Console.WriteLine("Index {0} is a BEAUTIFUL {1} {2}",
           Cars.IndexOf(c), c.Year, c.Model)
    ' e.g
    ' "Index 4 is a BEAUTIFUL 2015 Camry"
Next

Find one or the first of a kind:

Dim myCar = Cars.FirstOrDefault(Function (f) f.Make = "Mazda" AndAlso f.Year = 2013)

A List(Of T) can be used as a DataSource for some controls:

myDGV.DataSource = Cars

The DataGridView will create a column for each Property in the Car class, and add a row for each car object in the list – simple!

Or:

myListBox.DataSource
myList.DisplayMember = "Make"
myList.ValueMember = "Id"

The user will see the Make in the ListBox (or whatever you define). SelectedValue will be the Id of the car object they selected and SelectedItem will be the entire car object. No need to go rifling thru different arrays to find related data – it is always together in one spot.
