Populate labels when selecting item in listbox - listbox

Question

I have a listbox that contains the first index of every line in a text file.
the indexes are seperated with a ','.
I would like to select an item in the listbox and have it populate the labels I have in place with the rest of the line from the text file.
private void listsup_MouseClick(object sender, MouseEventArgs e)
{
Supfile = System.AppDomain.CurrentDomain.BaseDirectory + "data\\Suppliers.txt";
StreamReader spl = new StreamReader(Supfile);
string word = Convert.ToString(listsup.SelectedItem);
List<string> values = new List<string>();
foreach (string str in values)
{
if (str.Contains(word))
{
string[] tokens = str.Split(',');
labelsupnm.Text = tokens[0];
labelconpers.Text = tokens[1];
labeldiscr1.Text = tokens[2];
labeldiscr2.Text = tokens[3];
labeldiscr3.Text = tokens[4];
labeldiscr4.Text = tokens[5];
labeldiscr5.Text = tokens[6];
}
}
}
Problem is, I'm not getting anything to display in my labels, please help.

I changed my code a little, added some code that I used to populate the listbox itself, and now it all works just fine.
private void listsup_MouseClick(object sender, MouseEventArgs e)
{
Supfile = System.AppDomain.CurrentDomain.BaseDirectory + "data\\Suppliers.txt";
try
{
StreamReader supFile;
supFile = File.OpenText(Supfile);
string lines;
while (!supFile.EndOfStream)
{
lines = supFile.ReadLine();
string[] tokens = lines.Split(',');
string tr = listsup.SelectedItem.ToString();
if (tr.Equals(tokens[0]))
{
labelsupnm.Text = tokens[0];
labelconpers.Text = tokens[1];
labeldiscr1.Text = tokens[2];
labeldiscr2.Text = tokens[3];
labeldiscr3.Text = tokens[4];
labeldiscr4.Text = tokens[5];
labeldiscr5.Text = tokens[6];
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
