在ListBox中插入和获取对象数组

Question

我有一个产品类，有描述，库存和价格，我需要在列表框中插入描述，我做了：

Me.ListBox1.DataSource = productArray
Me.ListBox1.DisplayMember = "Descrition"
Me.ListBox1.ValueMember = "_Description" 

但现在，我需要获得所选项目的价格和库存才能与他们合作，但我无法找到办法。

Answer 1

将SelectedItem投射回产品类型。

Private Sub lsb_SelectedIndexChanged(sender As Object, e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
 Dim product As Product = DirectCast(ListBox1.SelectedItem, Product)
 Debug.WriteLine(product.Stock.ToString)
 Debug.WriteLine(product.Price.ToString)
End Sub
