winforms - c# add object to listbox and show string of object in it

Question

I'm using a ListBox and adding objects to it.

The object contains 2 variables, let's say username and userid.

How can I add the objects in the list (like listbox.Items.Add(object);) and show the username of that object?

Thnx!

You can use the DisplayMember and ValueMember properties to display the UserName property of your object and use its UserId property as the list item value:

class YourItem
{
    public string UserName { get; set; }
    public string UserId { get; set; }
}

yourListBox.DisplayMember = "UserName";
yourListBox.ValueMember = "UserId";

yourListBox.Items.Add(new YourItem {
    UserName = "FooName",
    UserId = "FooId"
});
