How to change the name of the selected item in a ListBox?

Question

.NET

Let's say there is a ListBox with elements "Value1", "Value2"
How to rename one of them during program execution?

Answer 1

private void button1_Click(object sender, EventArgs e)
{
    listBox1.Items[0] = ((String)listBox1.Items[0]).Replace('e','!') + "_Clicked";
}

Answer 2

// listbox lb - Your ListBox
// string newValue - New value
here lb.Items[lb.SelectedIndex] = newValue; // This code replaces the selected element with a new value. Instead of lb.SelectedIndex, you can specify the index of any other element. If there are no selected elements, you can catch an exception.
