IpcClientChannel Class

Implements a client channel for remote calls that uses the IPC protocol to transmit messages.

Namespace:  System.Runtime.Remoting.Channels.Ipc
Assembly:  System.Runtime.Remoting (in System.Runtime.Remoting.dll)

public class IpcClientChannel : IChannelSender, 
	IChannel, ISecurableChannel

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

The IpcClientChannel class uses the Windows interprocess communication (IPC) system to transport messages between application domains on the same computer. When communicating between application domains on the same computer, the IPC channel is much faster than the TCP or HTTP channels.

To perform additional processing of messages on the client side, you can specify an implementation of the IClientChannelSinkProvider interface through which all messages processed by the IpcClientChannel object will be passed.

By default, the IpcClientChannel class uses a binary formatter to serialize all messages.

A IpcClientChannel 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 IpcClientChannel constructor). For a list of these configuration properties, see the documentation for the IpcClientChannel constructor.

The following code example shows how to use the IpcClientChannel class.

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Ipc;

public class Client
    public static void Main ()
        IpcClientChannel clientChannel = new IpcClientChannel();

        RemotingConfiguration.RegisterWellKnownClientType( typeof(Counter) , "ipc://remote/counter" );

        Counter counter = new Counter();
        Console.WriteLine("This is call number {0}.", counter.Count);

#using <mscorlib.dll>
#using <System.Runtime.Remoting.dll>
#using <System.dll>
#using <Counter.dll>
using namespace System;
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Ipc;

public __gc class Client
    void ClientTest ()
        IpcClientChannel* clientChannel = new IpcClientChannel();

        RemotingConfiguration::RegisterWellKnownClientType( __typeof(Counter) , S"ipc://remote/counter" );

        Counter* counter = new Counter();
        Console::WriteLine(S"This is call number {0}.", __box(counter->Count));


int main(){
    Client* c = new Client();

The preceding code uses the following remote object.

using System;

public class Counter : MarshalByRefObject {

  private int count = 0;

  public int Count { get {
  } }

#using <mscorlib.dll>
using namespace System;

public __gc class Counter : public MarshalByRefObject {

  int count;


  __property int get_Count() {


For an example of a server that exposes this object remotely, see IpcServerChannel.
