I have a simple C# project, there's a list box & button, how to add new entry into listbox when I click at buton?

From the MSDN ListBox.ObjectCollection class documentation:

// Delay displaying the new items
listBox1.BeginUpdate();

// Loop through and add 50 items to the ListBox.
for (int x = 1; x <= 50; x++) {
   listBox1.Items.Add(&quot;Item &quot; + x.ToString());
}

// Allow the ListBox to repaint and display the new items.
listBox1.EndUpdate();
