示例1: HandleError
#region IErrorHandler Members
public bool HandleError(Exception error)
{
Console.WriteLine("HandleError called.");
// Returning true indicates you performed your behavior.
return true;
}
// This is a trivial implementation that converts Exception to FaultException<GreetingFault>.
public void ProvideFault(
Exception error,
MessageVersion ver,
ref Message msg
)
{
Console.WriteLine("ProvideFault called. Converting Exception to GreetingFault....");
FaultException<GreetingFault> fe
= new FaultException<GreetingFault>(new GreetingFault(error.Message));
MessageFault fault = fe.CreateMessageFault();
msg = Message.CreateMessage(
ver,
fault,
"http://microsoft.wcf.documentation/ISampleService/SampleMethodGreetingFaultFault"
);
}
#endregion示例2: AddBindingParameters
// This behavior modifies no binding parameters.
#region IServiceBehavior Members
public void AddBindingParameters(
ServiceDescription description,
ServiceHostBase serviceHostBase,
System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints,
System.ServiceModel.Channels.BindingParameterCollection parameters
)

}
// This behavior is an IErrorHandler implementation and
// must be applied to each ChannelDispatcher.
public void ApplyDispatchBehavior(ServiceDescription description, ServiceHostBase serviceHostBase)
{
Console.WriteLine("The EnforceGreetingFaultBehavior has been applied.");
foreach(ChannelDispatcher chanDisp in serviceHostBase.ChannelDispatchers)
{
chanDisp.ErrorHandlers.Add(this);
}
}
// This behavior requires that the contract have a SOAP fault with a detail type of GreetingFault.
public void Validate(ServiceDescription description, ServiceHostBase serviceHostBase)
{
Console.WriteLine("Validate is called.");
foreach (ServiceEndpoint se in description.Endpoints)
