Listbox displaying entire textfile in each enumeration

I am current making a ajax enabled asp.net 2.0 C# web page using Visual studio. net 2005 that monitors and displays status of various servers by pulling their names from a textfile then pinging them and displaying the results via a listbox.

Below is the code i am using, it enumerates though the textfile and pings correctly, but at each enumeration it displays the entire text of the textfile according to the info gained from that ping such as:

Server1 pings as online and it displays Servers1 through 13 as all online, Server 2 pings as down so it displays Server1 though 13 as down and so on. Any ideas on what is causing this or how to correct it? Thank you!


protected void Page_Load(object sender, EventArgs e)
    {
        string[] servers = File.ReadAllLines(Server.MapPath("TestFile.txt"));
        foreach (string svr in servers)
        {
            PingSvr(svr);
        }
    }
 
    public void PingSvr(string hostName)
    {
        string[] servers = File.ReadAllLines(Server.MapPath("TestFile.txt"));
        foreach (string svr in servers)
        {
            Ping pingSender = new Ping(); PingOptions options = new PingOptions();
            // Use the default Ttl value which is 128,
 
            // but change the fragmentation behavior. 
            options.DontFragment = true;
 
            // Create a buffer of 32 bytes of data to be transmitted. 
            string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
 
            byte[] buffer = System.Text.Encoding.ASCII.GetBytes(data);
            int timeout = 120;
            
            PingReply reply = pingSender.Send(hostName, timeout, buffer, options);
 
            if (reply.Status == IPStatus.Success)
            {
                ListBox1.Items.Add(svr + " is Online");
            }
 
            else
            {
                ListBox1.Items.Add("svr + "is Down");
            }
            
        }
 
    }
}

Hi

Your code has mistakes. I think the following code would do the job:

    protected void Page_Load(object sender, EventArgs e)
    {
        string[] servers = File.ReadAllLines(Server.MapPath("TestFile.txt"));
        foreach (string svr in servers)
        {
            PingSvr(svr);
        }
    }
 
    public void PingSvr(string hostName)
    {
            Ping pingSender = new Ping(); PingOptions options = new PingOptions();
            // Use the default Ttl value which is 128,
 
            // but change the fragmentation behavior. 
            options.DontFragment = true;
 
            // Create a buffer of 32 bytes of data to be transmitted. 
            string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
 
            byte[] buffer = System.Text.Encoding.ASCII.GetBytes(data);
            int timeout = 120;
            
            PingReply reply = pingSender.Send(hostName, timeout, buffer, options);
 
            if (reply.Status == IPStatus.Success)
            {
                ListBox1.Items.Add(hostName + " is Online");
            }
 
            else
            {
                ListBox1.Items.Add(hostName + " is Down");
            }
            
        }
