[RESOLVED] [2005] Struggling with array

[penguin5000]

Hello,
I'm struggling with something that is pretty basic

I want to create a Products array which stores the product id, a Quantity, and a Value.

I then want to loop through a DataTable containing the data, and put certain data from this table into the array.

With the array, I simply want to send this array over to another form (this bit, I can cope with), and display it in a ListView.

I've been messing around with brackets and curly brackets for ages, to no avail.

why not create a list of a structure something like this

Public Class Form1

    Private Structure Product
        Sub New(ByVal iID As Integer, ByVal iQuantity As Integer, ByVal iValue As Object)
            ID = iID
            Quantity = iQuantity
            Value = iValue
        End Sub

        Dim ID As Integer
        Dim Quantity As Integer
        Dim Value As Object
    End Structure

    Private Products As New List(Of Product)

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Products.Add(New Product(1, 14, 1.456))
    End Sub
End Class

If all productid, qty and value are of the same datatype (double, for example) then you can use a strongly typed array... Otherwise, you'll have to declare your array as an array of object then cast it back to the correct type when retreiving the values form the elements... Having said that, it's a bad idea to use an array of objects. So instead, you should create a Product structure or class then create an array of type Product.

Excellent. Thanks guys. I'd have never have thought of doing this.
