IChannel IChannel IChannel IChannel Interface

Definition

Defines the basic interface that all channel objects must implement. It requires that they implement the state machine interface shared by all communication objects and that they implement a method to retrieve objects from the channel stack.

public interface class IChannel : System::ServiceModel::ICommunicationObject
public interface IChannel : System.ServiceModel.ICommunicationObject
type IChannel = interface

Remarks

Important

Calling methods from classes that implement this interface with untrusted data is a security risk. Call the methods from classes that implement this interface only with trusted data. For more information, see Data Validation.

Channels must satisfy the contract of a state machine as defined by the ICommunicationObject interface.

The IChannel interface adds the

GetProperty method to the ICommunicationObject interface. This method provides a mechanism for retrieving properties from the channel stack regardless of where in the stack those properties live. The term "property" in the method name refers to a piece of information that belongs to one of the channels in the stack. The CLR type for that property is determined by T. This method of retrieval is also used on channel factories and channel listeners.

IChannel is inherited by each of the channel interfaces associated with the basic message-exchange patterns:
