ChannelDispatcherBase.Attach Method (ServiceHostBase)


When overridden in a derived class, attaches the channel dispatcher to a specific host.

Namespace:   System.ServiceModel.Dispatcher
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

protected virtual void Attach(
	ServiceHostBase host


Type: System.ServiceModel.ServiceHostBase

The ServiceHostBase for the service.

Exception Condition

host is null.


The communication object is in an Opening or Opened state or the host is already set.


The communication object is in a Closing or Closed state.


The communication object is in a Faulted state.

This method can only be set when the instance of the ChannelDispatcher is in the Created state, as this is the only state that is both mutable and not disposed.

A ServiceHost calls this method when the ChannelDispatcherBase is added to its ChannelDispatchers collection. This gives the ChannelDispatcherBase a chance to hook events and inspect the ServiceHost, and provides the value that should be returned from the Host property.
