c# - Problem in binding a listbox to data -


I have a table with these fields: id, name

I have built a listback in the table.

My question is, when the user has selected an item in the list, how will I know what is the ID of the chosen item?

Note: ID is not equal to the selected index or items of items are not in the ID

< P> Eg

Assume that you have a datatable dt, it has column ID and name. Then binding contains the following code, 

  this.listbox.DataSource = dt; This.listbox.DisplayMember = "name"; This.listbox.ValueMember = "id";   
 While reading selected values ​​for the listbox,  
  this.listbox.SelectedItem  will give you the selected name and  
  this.listbox.SelectedValue  will give you the relevant ID
