IpcClientChannel Class

Definition

Namespace:

System.Runtime.Remoting.Channels.Ipc

Assembly:

System.Runtime.Remoting.dll

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

public ref class IpcClientChannel : System::Runtime::Remoting::Channels::IChannelSender, System::Runtime::Remoting::Channels::ISecurableChannel

public class IpcClientChannel : System.Runtime.Remoting.Channels.IChannelSender, System.Runtime.Remoting.Channels.ISecurableChannel

type IpcClientChannel = class
    interface IChannelSender
    interface IChannel
    interface ISecurableChannel

Public Class IpcClientChannel
Implements IChannelSender, ISecurableChannel

Examples

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

#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 ref class Client
{
public:
   void ClientTest()
   {
      IpcClientChannel^ clientChannel = gcnew IpcClientChannel;
      ChannelServices::RegisterChannel( clientChannel );

      RemotingConfiguration::RegisterWellKnownClientType( Counter::typeid, L"ipc://remote/counter" );
      Counter^ counter = gcnew Counter;
      Console::WriteLine( L"This is call number {0}.", counter->Count );
   }
};

int main()
{
   Client^ c = gcnew Client;
   c->ClientTest();
}

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();
        ChannelServices.RegisterChannel(clientChannel);

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

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

The preceding code uses the following remote object.

using namespace System;
public ref class Counter: public MarshalByRefObject
{
private:
   int count;

public:
   Counter()
   {
      count = 0;
   }

   property int Count 
   {
      int get()
      {
         return (count)++;
      }
   }
};

using System;

public class Counter : MarshalByRefObject {

  private int count = 0;

  public int Count { get {
    return(count++);
  } }
}

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

Remarks

Important

Calling methods from this class with untrusted data is a security risk. Call the methods from this class only with trusted data. For more information, see Validate All Inputs.

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.

Constructors

IpcClientChannel()	Initializes a new instance of the IpcServerChannel class.
IpcClientChannel(IDictionary, IClientChannelSinkProvider)	Initializes a new instance of the IpcClientChannel class with the specified configuration properties and sink.
IpcClientChannel(String, IClientChannelSinkProvider)	Initializes a new instance of the IpcClientChannel class with the specified name and sink.

Properties

ChannelName	Gets the name of the current channel.
ChannelPriority	Gets the priority of the current channel.
IsSecured	Gets or sets a Boolean value that indicates whether the current channel is secure.

Methods

CreateMessageSink(String, Object, String)	Returns a channel message sink that delivers messages to the specified URL or channel data object.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Parse(String, String)	Extracts the channel URI and the remote well-known object URI from the specified URL.
ToString()	Returns a string that represents the current object. (Inherited from Object)
