hi i have following code to send file and its giving file io error

namespace client_server
{
    class Program
    {
        static void Main(string[] args)
        {
            IPAddress ip = IPAddress.Parse("127.0.0.1");
            TcpListener tcp = new TcpListener(ip, 1234);
            tcp.Start();
            Console.WriteLine("server started");
            while (true)
            {
                Socket socket = tcp.AcceptSocket();
                if (socket.Connected)
                {
                    CHandler clH = new CHandler(socket);
                    Thread t = new Thread(new ThreadStart(clH.Task));
                    t.Start();
                }
            }
        }
    }


    class CHandler
    {
        Socket socket;
        public CHandler(Socket s) { socket = s; }
        public void Task()
        {
            string path = "C:/";
            NetworkStream net = new NetworkStream(socket);
            StreamReader nIn = new StreamReader(net);
            StreamWriter nOut = new StreamWriter(net);
            string fName = nIn.ReadLine();
            path = path + fName;

            try
            {
                StreamReader fIn = new StreamReader(path);
                string nextLine;
                Console.WriteLine("sending file");
                nextLine = fIn.ReadLine();
                while (nextLine != null)
                {

                    nOut.WriteLine(nextLine);
                    nOut.Flush();
                    nextLine = fIn.ReadLine();
                }
                Console.WriteLine("file sent");
                fIn.Close();
                net.Close();
                nOut.Close();
                socket.Close();
            }
            catch { Console.WriteLine("file IO error"); }
        }
    }
}



namespace clientside
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("enter the file name");
            string name = Console.ReadLine();
            TcpClient serSocket;
            try
            {
                serSocket = new TcpClient("127.0.0.1", 1234);
            }
            catch
            {
                Console.WriteLine("Failed to connect");
                return;
            }
            NetworkStream net = serSocket.GetStream();
            StreamWriter sOut = new StreamWriter(net);
            StreamReader sIn = new StreamReader(net);

            try
            {
                sOut.WriteLine(name);
                sOut.Flush();
                string nextLine = sIn.ReadLine();
                while (nextLine != null)
                {
                    Console.WriteLine(nextLine);
                    nextLine = sIn.ReadLine();
                }
                sIn.Close();
                net.Close();
            }
            catch
            {
                Console.WriteLine("error reading from server");
            }


            Console.ReadKey();
        }
    }

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

On what line is the error?
What exactly is the full error?

[koneyji]

can't find the exactly where the error is?
i think the error is somewhere here

 try
            {
                StreamReader fIn = new StreamReader(path);
                string nextLine;
                Console.WriteLine("sending file");
                nextLine = fIn.ReadLine();
                while (nextLine != null)
                {
 
                    nOut.WriteLine(nextLine);
                    nOut.Flush();
                    nextLine = fIn.ReadLine();
                }
                Console.WriteLine("file sent");
                fIn.Close();
                net.Close();
                nOut.Close();
                socket.Close();

thanks for the reply

To have this break on the exact line producing the code you need to make a change to your settings. Next time you debug this, Visual Studio will stop softly on any exception when it is Thrown instead of only when it goes unhandled.

Debug menu
Exceptions
Check on "CLR"

thank you

the error is in
StreamReader fIn = new StreamReader(pa th);

it says
{"Access to the path 'D:\\datafiles\ \data' is denied."}

i think it is a folder privacy issue..

Well there ya go. Glad we could help you track down the exact nature of the problem: You don't have permissions in that folder or to that item. Mystery solved.
