Displaying user input into listbox

Question

 Hello,

I am making a winform application that retrieves data from user with text box, and display on listBox. 

Below is the ones I tried, but no error, and it's not working. 

Help please! :) 

 

private void Button_Click(object sender, EventArgs e)

{

          current.name = nameTextBox.Text.Trim();

          current. description = descriptionTextBox.Text.Trim(); 

 

          listBox.BeginUpdate();

          listBox.Items.Clear();

          string row = String.Format ("{0} {1}", current.name, current description);

          //listBox.Items.Add("{0} {1}", current.name, current description); //Another method I tried, but didn't work.

          listBox.EndUpdate(); 

 

}
