How to copy all the listbox items to another listbox in WPF?

[VahidEra]

Hi guys,
I have a listbox in my WPF project and I want to copy all its items to another listbox But unfortunately, I encounter an error:

Unable to cast object of type 'System.String' to type 'System.Windows.Controls.ListBoxItem'.'

this is my cod:

dim list As New List(Of String)
list.Clear()

        For Each lbi As ListBoxItem In ListBox1.Items            
            list.Add(lbi.Content.ToString())
        Next lbi

Where is the problem with my cod?

You are iterating over the elements of ListBox1.Items and expect them to be ListBoxItems but the errors tells you that is not the case, there are just strings in the Items property in this case. So you should be able to do

For Each lbi As String In ListBox1.Items
    list.Add(lbi);
Next lbi
