How to bind Dictionary to ListBox in WinForms

Question

It is possible to bind a Dictionary to a Listbox, keeping in sync between the Listbox and the member property?

Answer 1

var choices = new Dictionary(); 
choices["A"] = "Arthur"; 
choices["F"] = "Ford"; 
choices["T"] = "Trillian"; 
choices["Z"] = "Zaphod"; 
listBox1.DataSource = new BindingSource(choices, null); 
listBox1.DisplayMember = "Value"; 
listBox1.ValueMember = "Key"; 

(Shamelessly lifted from my own blog: Bind a ComboBox to a generic Dictionary.)

This means you can use SelectedValue to get hold of the corresponding dictionary key for the selected item in the ListBox.
