Serialization of arrays (Recipe program)

[erikaslt66]

Hello, I am looking for solution that will help me to store an data in arrays, so that next time when i open program i could open it and it will be in the save form.
Serialization is the thing that I would need to do, but I really find hard to understand it, where does these variables go and how to use this process to convert data in XML or binary. Any help would be appreciated. Thanks.

Public Class Form1
    Dim recipename As String
    Dim recipeserves As Integer
 
    Dim ingredients(25) As String
    Dim index As Integer
    Dim ingredientindex As Integer
    Dim ingredientquantity(25) As Integer
    Dim ingredientunit(25) As String
 
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        recipename = InputBox("Please enter your recipe name.")
        recipeserves = InputBox("Please enter serves number for this recipe.")
        index = InputBox("Please enter ingredients number.")
 
        txtnames.Text = recipename
        txtserves.Text = recipeserves
 
 
 
        'For recipe ingredients
        For Me.ingredientindex = 1 To index
            ingredients(ingredientindex) = InputBox("Please enter ingredient name.")
            ingredientquantity(ingredientindex) = InputBox("Please enter ingredient quantity for the following ingredient.")
            ingredientunit(ingredientindex) = InputBox("Please enter ingredient unit for the following ingredient")
        Next
        For Me.ingredientindex = 1 To index
            lstbox.Items.Add(ingredients(ingredientindex))
            lstbox1.Items.Add(ingredientquantity(ingredientindex))
            lstbox2.Items.Add(ingredientunit(ingredientindex))
        Next
 
 
 
    End Sub
 
    ' Dim filename As String
 
    ' Private Sub btnsave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsave.Click
 
    'Saving to text file
    '    filename = InputBox("Please enter a filename")
    ' FileOpen(1, filename, OpenMode.Output)
    ' For Me.ingredientindex = 1 To index
    '      PrintLine(1, ingredients(ingredientindex) & " " & ingredientquantity(ingredientindex) & " " & ingredientunit(ingredientindex))
    '  Next
    '  FileClose(1)
