Sending files over the network with .NET

Griffin.Framework has built in support for streams if you are using MicroMsg. This example will demonstrate how you can send a file stream over the network.

Install the nuget package “griffin.framework” and create a console application with the following code:

class Program
{
    static void Main(string[] args)
    {
        var server = new ChannelTcpListener();
        server.MessageReceived = OnServerReceivedMessage;
        server.Start(IPAddress.Any, 0);

        var client = new ChannelTcpClient<object>(
            // data contract will be used for plain .NET objects 
            new MicroMessageEncoder(new DataContractMessageSerializer()),
            new MicroMessageDecoder(new DataContractMessageSerializer())
        );

        client.ConnectAsync(IPAddress.Loopback, server.LocalPort);
        client.SendAsync(new FileStream("TextSample.txt", FileMode.Open)).Wait();

        Console.ReadLine();
    }

    private static void OnServerReceivedMessage(ITcpChannel channel, object message)
    {
        var file = (Stream)message;
        var reader = new StreamReader(file);
        var fileContents = reader.ReadToEnd();
        Console.WriteLine(fileContents);
    }
}

The library can send/receive any type of stream of any size (as long as the size is known). The client will automatically create a MemoryStream or FileStream depending on the stream size. So it doesn’t matter if the stream is 4Gb or 2Kb.
