我有一个自定义行为,我实现“IParameterInspector”,以便能够使用BeforeCall和AfterCall.我正在使用这些方法在我的WCF服务上执行调用之前进行一些验证.
这是我的属性:
[AttributeUsage(AttributeTargets.Class)]
public class SendReceiveBehaviorAttribute : Attribute, IServiceBehavior
{
public SendReceiveBehaviorAttribute()
{
}
public void ApplyDispatchBehavior(ServiceDescription desc, ServiceHostBase host)
{
foreach (ChannelDispatcher cDispatcher in host.ChannelDispatchers)
{
foreach (EndpointDispatcher eDispatcher in cDispatcher.Endpoints)
{
foreach (DispatchOperation op in eDispatcher.DispatchRuntime.Operations)
{
op.ParameterInspectors.Add(MyInspector);
}
}
}
}
public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, Collection<ServiceEndpoint> endpoints, BindingParameterCollection bindingParameters)
{
}
public void Validate(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
{
}
}
我的检查员:
internal class MyInspector: IParameterInspector
{
public void AfterCall(string operationName, object[] outputs, object returnValue, object correlationState)
{
}
public object BeforeCall(string operationName, object[] inputs)
{
// Make some verifications and cancel if it fails.
return null;
}
}

如果我的验证失败,最好的中止通话方式是什么?
最佳答案 抛出异常是唯一的方法 – 据我所知 – 中止.
