Question

I am trying to get all the data from a combo-box in vb. Lets say the values are john, sarah, bob. I want to be able to write those to a text file like this:

John
Sarah
Bob

They were added using

combobox.add.item(sarah)  

Is there anyway I can do somthing like this?

names = combobox.list.items

Answer 1

In c# it would be something like this

string names = string.Join(", ", comboBox.Items.Cast<object>()
                                         .Select(i => i.ToString()));

Here’s the same snippet (auto)translated to vb.net

Dim names As String = String.Join(", ", comboBox.Items.Cast(Of Object)().Select(Function(i) i.ToString()))

Or you can do a simple loop through all the items and use a stringbuilder and concatenate each item.

Dim sb As New StringBuilder()
For Each item As Object In comboBox.Items
    sb.AppendFormat("{0}, ", item)
Next
Dim names As String = sb.ToString()
