How to get the ValueMember of an item in a Listbox for a given index number?

Question

I have a ListBox which holds aDisplayMember called "Data" and a ValueMember called "Number". I want to get the ValueMember of all the items using a loop as following.

for (int i = 0; i < ListBox1.Items.Count; i++)
{ 
    //Get the `ValueMember` of `Item` where it's `Index` is `i` 
}

Answer 1

Did you tried like code below:

for (int i = 0; i < ListBox1.Items.Count; i++)
{ 
   Console.WriteLine((ListBox1.Items[i] as YourItemClassType).Number.ToString());
}

YourItemClassType is your class that you adding to ListBox1, YourItemClassType contains Number and Data properies

Hope helps
