Hi there ,

hope to find some informations about Smtp pop client in mono.
I have looked in Mono Documentation. There is only C# code explained.
Where to start ? :roll:

My interest is in the general networking functions such like TCP/IP and other for inplementing
networking function in an application with cobra code. Not : C# code
Thus any example code for those that is explaining the "includings of such libraries inside Mono"
in the cobra code would be a pleasant matter. :mrgreen:

The matter is to beat languages like Python that have networking libraries in and also some clear and
practical examples. :shock:

I MEAN THIS EXAMPLES FROM PYTHON STANDARD LIBRARY:

Code: Select all: >>> from urllib.request import urlopen >>> with urlopen('http://tycho.usno.navy.mil/cgi-bin/timer.pl') as response: ... for line in response: ... line = line.decode('utf-8') # Decoding the binary data to text. ... if 'EST' in line or 'EDT' in line: # look for Eastern Time ... print(line) <BR>Nov. 25, 09:43:32 PM EST >>> import smtplib >>> server = smtplib.SMTP('localhost') >>> server.sendmail('soothsayer@example.org', 'jcaesar@example.org', ... """To: jcaesar@example.org ... From: soothsayer@example.org ... ... Beware the Ides of March. ... """) >>> server.quit()

Mono has definetly networking protocolls in but in C# language.
Thus an example in Cobra is a must in my opinion. :!:

ONLY COBRA ! Cobra can beat Python. That is a shure thing. But everyone must SEE the methods.

If you've found C# code using networking you have everything you need.
All you have to do is write or convert the C# code to corresponding cobra code - or write cobra code accessing the same C# library API.

I dont have any examples for smtp but heres one for a SocketServer

# Sample for a Server using .Net sockets

use System.IO
use System.Net
use System.Net.Sockets

class AsynchIOServer
    def main is shared
        tcpListener = TcpListener(1032)
        tcpListener.start
        socketForClient = tcpListener.acceptSocket
        if socketForClient.connected
            #Console.writeLine("Client connected")
            print "Client connected"
            networkStream = NetworkStream(socketForClient)
            streamWriter = System.IO.StreamWriter(networkStream)
            streamReader = System.IO.StreamReader(networkStream)
            theString = "Sending"
            streamWriter.writeLine(theString)
            #Console.writeLine(theString)
            print theString
            streamWriter.flush
            theString = streamReader.readLine to !
            #Console.writeLine(theString)
            print theString
            streamReader.close
            networkStream.close
            streamWriter.close

        socketForClient.close
        #Console.WriteLine("Exiting...")
        print "Exiting..."

Heres the corres Socket client

class Client

        def main is shared
                #args = CobraCore.commandLineArgs
                try
                        socketForServer = TcpClient("localHost", 1032)
                catch
                        #Console.WriteLine("Failed to connect to server at 0:999", "localhost")
                        print  "Failed to connect to server at 0:999", "localhost"
                        return

                networkStream = socketForServer.getStream
                streamReader = System.IO.StreamReader(networkStream)
                streamWriter = System.IO.StreamWriter(networkStream)
                try
                        outputString as String?
                        # read the data from the host and display it
                        outputString = streamReader.readLine
                        print outputString # Console.WriteLine(outputString)
                        streamWriter.writeLine("Client Message")
                        print "Client Message" # Console.WriteLine("Client Message")
                        streamWriter.flush
                catch
                        print "Exception reading from Server" #Console.WriteLine("Exception reading from Server")

( thought I had some converted examples from the .Net.Sockets sample code ( C# converted to cobra) but couldnt find them.
