Question

How can I copy a collection of items in a comboBox to a StringCollection in my C# application? I’m only interested in capturing the string text for each item in their respective order. I am trying to make a MRU file list that is saved between sessions, so I would like to copy comboBox.Items to StringCollection Properties.Settings.Default.MostRecentlyUsedHexFiles. Any thoughts or suggestions you may have would be appreciated. Thanks.

You should be able to loop over the combobox.items and simply use stringcollection.Add() to add the string to the collection.

The tostring method will perform as described here:

Although the ComboBox is typically
used to display text items, you can
add any object to the ComboBox.
Typically, the representation of an
object in the ComboBox is the string
returned by that object’s ToString
method. If you want to have a member
of the object displayed instead,
choose the member that will be
displayed by setting the DisplayMember
property to the name of the
appropriate member. You can also
choose a member of the object that
will represent the value returned by
the object by setting the ValueMember
property. For more information, see
ListControl.

So something like:

Foreach(object o in combobox.items)
{
//might need to access a datamember of the combobox's item if more complex solution is required, but this will probably do
stringcollection.Add(o.ToString);
}
