you can use TCP client to connect to other pc using their Ip address and port no private void btnSend_Click(object sender, EventArgs e) { string ipAddress = txtIPAddress.Text; int port = int .Parse(txtPort.Text); string fileName = txtFile.Text; Task.Factory.StartNew(() => SendFile(ipAddress,port, fileName,shortFileName)); MessageBox.Show( "File Sent" ); } public void SendFile(string remoteHostIP, int remoteHostPort , string longFileName, string shortFileName) { try { if (!string.IsNullOrEmpty(remoteHostIP)) { byte[] fileNameByte = Encoding.ASCII.GetBytes (shortFileName); byte[] fileData = File.ReadAllBytes(longFileName); byte[] clientData = new byte[4 + fileNameByte.Length + fileData.Length]; byte[] fileNameLen = BitConverter.GetBytes( fileNameByte.Length); fileNameLen.CopyTo(clientData, 0); fileNameByte.CopyTo(clientData,4); fileData.CopyTo(clientData, 4 + fileNameByte.Length); TcpClient clientSocket = new TcpClient(remoteHostIP, remoteHostPort); NetworkStream networkStream = clientSocket.GetStream(); networkStream.Write(clientData, 0, clientData.GetLength (0)); networkStream.Close(); } } catch { } } }

Each pc is identified by an IP address, a file can be copied using File.Copy(..) function. You just need to design fancy stuffs as per your need
