only last value is sent

I was wondering if anyone could tell me why it only appends the last row of data in my listbox to my xmlserializer to write it to my xml file....the infomation comes in the listBox but only the last row of data is written to the xml file.....why is that? and how would i go about fixing that...any help would be great!

empinfo info =new empinfo();

string connect = System.Configuration.ConfigurationSettings.AppSettings["connstring"];

SqlConnection sql =new SqlConnection(connect);

string cmd = "Select * From Employees";

SqlCommand scmd =new SqlCommand(cmd, sql);

sql.Open();

SqlDataReader dr = scmd.ExecuteReader();

if(dr.HasRows)

{

while(dr.Read())

{

//string lname = "";

//string fname = "";

//string title = "";

//string titof = "";

//string et = "";

//string info = "";

string info1 = "";

info.d_titof = dr.GetValue(4).ToString();

info.d_fname = dr.GetValue(2).ToString();

info.d_lname = dr.GetValue(1).ToString();

info.d_title = dr.GetValue(3).ToString();

info.d_ext = dr.GetValue(13).ToString();

info1 = info.d_titof + " " + info.d_fname + " " + info.d_lname + " " + info.d_title + " " + info.d_ext;

listBox1.Items.Add(info1).ToString();

try

XmlSerializer xs =new XmlSerializer(typeof(empinfo));

Stream st =new FileStream("c:\\vic1.xml", FileMode.Create, FileAccess.Write, FileShare.None);

xs.Serialize(st, info);

st.Close();

}

catch(Exception es)

{

MessageBox.Show(es.ToString(), "Erorr");

}

}

sql.Close();

dr.Close();

scmd.Dispose();
