TcpServerChannel Class

Implements a server channel for remote calls that uses the TCP protocol to transmit messages.

Namespace: System.Runtime.Remoting.Channels.Tcp
Assembly: System.Runtime.Remoting (in system.runtime.remoting.dll)

public class TcpServerChannel : IChannelReceiver, IChannel, ISecurableChannel
public class TcpServerChannel implements IChannelReceiver, IChannel, 
	ISecurableChannel
public class TcpServerChannel implements IChannelReceiver, IChannel, 
	ISecurableChannel

Channels transport messages across remoting boundaries (for example, computers or application domains). The TcpServerChannel class transports messages using the TCP protocol.

Channels are used by the .NET Framework remoting infrastructure to transport remote calls. When a client makes a call to a remote object, the call is serialized into a message that is sent by a client channel and received by a server channel. It is then deserialized and processed. Any returned values are transmitted by the server channel and received by the client channel.

To perform additional processing of messages on the server side, you can specify an implementation of the IServerChannelSinkProvider interface through which all messages processed by the TcpServerChannel instance are passed.

The TcpServerChannel instance accepts messages serialized in either binary or SOAP format.

A TcpServerChannel object has associated configuration properties that can be set at run time either in a configuration file (by invoking the static RemotingConfiguration.Configure method) or programmatically (by passing a IDictionary collection to the TcpServerChannel constructor). For a list of these configuration properties, see Channel and Formatter Configuration Properties.

NoteNote

If the server computer is running Windows 95/98/Me, the TcpServerChannel cannot be specified as secure.

The following code example shows the use of a remotable type.

using System;
using System.Runtime.Remoting;

public class Remotable : MarshalByRefObject
{

    private int callCount = 0;

    public int GetCount()
    {
        callCount++;
        return(callCount);
    }

}

The following code example shows the use of the TcpServerChannel class to expose a remotable type.

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Security.Permissions;

public class Server
{
    [SecurityPermission(SecurityAction.LinkDemand)]
    public static void Main()
    {
 
        // Set up a server channel.
        TcpServerChannel serverChannel = new TcpServerChannel(9090);
        ChannelServices.RegisterChannel(serverChannel);    

        // Expose an object for remote calls.
        RemotingConfiguration.RegisterWellKnownServiceType(
            typeof(Remotable), "Remotable.rem", WellKnownObjectMode.Singleton
        );

        // Show the name and priority of the channel.
        Console.WriteLine("Channel Name: {0}", serverChannel.ChannelName);
        Console.WriteLine("Channel Priority: {0}", serverChannel.ChannelPriority);

        // Show the URIs associated with the channel.
        ChannelDataStore data = (ChannelDataStore) serverChannel.ChannelData;
        foreach (string uri in data.ChannelUris)
        {
            Console.WriteLine(uri);
        }

        // Wait for method calls.
        Console.WriteLine("Listening...");
        Console.ReadLine();

    }

}
