Pulling text from a text file by line and putting into variables to be used and displayed

I am current making a ajax enabled asp.net 2.0 C# web page using Visual studio. net 2005  that pings 13 servers at timed intervals. Everything is finished except i am trying to figure out how to get the webpage to read a text file line by line and store the names of each server in variables as it reads the text file to be used to ping and display the information.

Like you have the variable sHost and the page loads and first name in the file is server1, so it takes server1 and puts it into sHost so PingServer1("sHost") pings server1 and Label1.text = "sHost is up" displays on the page as server1 is up. Then it moves on to second line fo text which is server2 and it repeats the process till all are listed.

Not sure if its possiable the way i described but any ideas are greatly appreciated!

use the following code

using System.IO;

string[] servers = File.ReadAllLines("path_to_server_file");
foreach (string svr in servers)
{
     HostTheServer(svr);
     Console.WriteLine("{0} is up", svr);
}

The console.Writeline was just an example of how you could process each line that you read from the file.
Sorry for confusing you.

the File.ReadAllLines() method reads all the lines in a text file and returns an array of strings. You can iterate through the array to obtain each line of the file and assign them to the required variables.

This is because you are looping through all the string and setting the label's value to each string within the loop.
Obviously at the end of the loop, the label will have the last line of text.

Do this instead:

Remove the label and add a ListBox
and with the loop do the following


using System.IO;
 

string[] servers = File.ReadAllLines("path_to_server_file");

foreach (string svr in servers)

{

     HostTheServer(svr);

     listBox1.Items.Add(svr);

}

Open in new window
