SqlDataReader.Read() - возвращает bool, а надо string

using (SqlConnection connection = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=...;Integrated Security=True;User Instance=True;"))
{
      SqlCommand getname = new SqlCommand("SELECT usersite FROM sites WHERE useralias='"  + theAlias + "'", connection);
      connection.Open();
      SqlDataReader sltext = getname.ExecuteReader();
      siteLabel.Text = sltext.Read();//ругается так: Cannot implicitly convert type 'bool' to 'string'
}

siteLabel.Text = sltext.Read();

siteLabel.Text = sltext.Read().ToString();

using (SqlConnection connection = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=...;Integrated Security=True;User Instance=True;"))
{
    SqlCommand command = new SqlCommand("SELECT usersite FROM sites WHERE useralias='"  + theAlias  + "'", connection);
 
    connection.Open();
 
    SqlDataReader reader = command.ExecuteReader();
 
    // Call Read before accessing data.
    while (reader.Read())
    {
        siteLabel.Text = String.Format("{0}", reader[0]);
    }
 
    // Call Close when done reading.
    reader.Close();
}
