wcf Handling exceptions Using a custom error logging framework
Example
It is sometimes useful to integrate a custom error logging framework to ensure all exceptions are logged.
[ServiceContract]
[ErrorHandler]
public interface IMyService
{
}
[AttributeUsage(AttributeTargets.Interface)]
public class CustomErrorHandler : Attribute, IContractBehavior, IErrorHandler
{
public bool HandleError(Exception error)
{
return false;
}
public void ProvideFault(Exception error, MessageVersion version, ref Message fault)
{
if (error == null)
{
return;
}
//my custom logging framework
}
public void ApplyDispatchBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, DispatchRuntime dispatchRuntime)
{
dispatchRuntime.ChannelDispatcher.ErrorHandlers.Add(this);
}
public void ApplyClientBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint,
ClientRuntime clientRuntime)
{
}
public void AddBindingParameters(ContractDescription contractDescription, ServiceEndpoint endpoint,
BindingParameterCollection bindingParameters)
{
}
public void Validate(ContractDescription contractDescription, ServiceEndpoint endpoint)
{
}
}
