Function description---------------------------------------------

This function creates a server service that listens for incoming requests.

As a request is received, the respective file is located and the file size is sent.

The number of 512 byte sectors is also sent, for loop control in the Electronic class schedule program.

The program then waits for a start bit signifying that it can send the raw file data.

When the raw data is sent, the file server program ends the connection and begins to listen again.

public void RunServer()

{

try

{

// Fetches local IP address

string hostname = Dns.GetHostName();

IPAddress[] ips = Dns.GetHostAddresses(hostname);

string ip = String.Empty;

if (ips.Length > 0)

{

ip = ips[0].ToString();

}

// Creates listener port 2000 local IP address

Int32 port = 2000;

IPAddress localAddr = IPAddress.Parse(ip); server

= new TcpListener(localAddr, port);
