.NET Framework Class Library

ChannelServices..::.RegisterChannel Method (IChannel, Boolean)

Registers a channel with the channel services.

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

Syntax

Visual Basic (Declaration)

<SecurityPermissionAttribute(SecurityAction.Demand, Flags := SecurityPermissionFlag.RemotingConfiguration)> _
Public Shared Sub RegisterChannel ( _
    chnl As IChannel, _
    ensureSecurity As Boolean _
)

Visual Basic (Usage)

Dim chnl As IChannel
Dim ensureSecurity As Boolean

ChannelServices.RegisterChannel(chnl, ensureSecurity)

[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.RemotingConfiguration)]
public static void RegisterChannel(
    IChannel chnl,
    bool ensureSecurity
)

Visual C++

[SecurityPermissionAttribute(SecurityAction::Demand, Flags = SecurityPermissionFlag::RemotingConfiguration)]
public:
static void RegisterChannel(
    IChannel^ chnl, 
    bool ensureSecurity
)

JScript

public static function RegisterChannel(
    chnl : IChannel, 
    ensureSecurity : boolean
)

Parameters

chnl: Type: System.Runtime.Remoting.Channels..::.IChannel
The channel to register.

ensureSecurity: Type: System..::.Boolean
true ensures that security is enabled; otherwise false. Setting the value to false will not nullify the security setting done on the TCP or IPC channel. For details, see Remarks.

Exceptions

Exception	Condition
ArgumentNullException	The chnl parameter is nullNothingnullptra null reference (Nothing in Visual Basic).
RemotingException	The channel has already been registered.
SecurityException	At least one of the callers higher in the call stack does not have permission to configure remoting types and channels.
NotSupportedException	Not supported in Windows 98 for TcpServerChannel and on all platforms for HttpServerChannel. Host the service using Internet Information Services (IIS) if you require a secure HTTP channel.

Remarks

The RegisterChannel(IChannel, Boolean) method receives the IChannel interface from a channel object. Either the channel's ChannelName must be unique, or the channel must be anonymous. A channel is anonymous if the IChannel..::.ChannelName is set to either nullNothingnullptra null reference (Nothing in Visual Basic) or Empty by using the name configuration property.

You cannot register two channels with the same name in a AppDomain. By default, the name of a HttpChannel is "http" and the name of a TcpChannel is "tcp". Therefore, if you want to register two channels of the same type, you must specify a different name for one of them through configuration properties.

For more information about channel configuration properties, see Channel and Formatter Configuration Properties and [<topic://gnconchanneltemplate>].

If the ensureSecurity parameter is set to true, the remoting system determines whether the channel implements ISecurableChannel, and if so, enables encryption and digital signatures. An exception is thrown if the channel does not implement ISecurableChannel.

Note:
Setting ensureSecurity to true throws a RemotingException for TcpServerChannel on win98 (Since secure tcp channel is not supported on wi9x) , and for Http Server Channel on all platforms (Users need to host service in IIS if they want secure http channel).
