Update listbox

[Vandy02]

I have listbox that I populate with data from a text file..
I select an item and populate a textbox(txtFileText) with the item I selected...I want to be able to modify the data and then update the list with the btnUpdLst_Click

I was able to do this in VB .net...but unable to do so in C #...

private void listBox1_SelectedIndexChanged(object sender, System.EventArgs e)
{
txtFileText.Text = listBox1.SelectedItem.ToString();
j = listBox1.SelectedItem.ToString();
j2 = listBox1.SelectedIndex; }

private void btnUpdLst_Click(object sender, System.EventArgs e)
{
listBox1.Items[j2] = txtFileText.Text;

}

and what's not working?

here's what I use and it works:

int selectedIndex = -1;

private void listBox1_SelectedIndexChanged(object sender, System.EventArgs e)
{
     if (listBox1.SelectedItem != null)
     {
           textBox1.Text = listBox1.SelectedItem.ToString();
           selectedIndex = listBox1.SelectedIndex;
     }
}

private void Button1_Click(object sender, System.EventArgs e)
{
     listBox1.Items[selectedIndex] = textBox1.Text
}
