IOperationBehavior.ApplyClientBehavior Method (OperationDescription, ClientOperation)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Implements a modification or extension of the client across an operation.

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

void ApplyClientBehavior(
	OperationDescription operationDescription,
	ClientOperation clientOperation


Type: System.ServiceModel.Description.OperationDescription

The operation being examined. Use for examination only. If the operation description is modified, the results are undefined.

Type: System.ServiceModel.Dispatcher.ClientOperation

The run-time object that exposes customization properties for the operation described by operationDescription.

Implement the ApplyClientBehavior method to view, modify, or add a custom extension to the client runtime across all messages used with a specific operation. For details about what customizations you can do with a client run-time object, see ClientRuntime and ClientOperation.

It is recommended that the ApplyClientBehavior method throw a NotImplementedException if the behavior is only intended for use in a service application.

The following code example shows an implementation of System.ServiceModel.Dispatcher.IParameterInspector that writes to the console when the inspector is invoked on an operation. This customization can only be attached to the System.ServiceModel.Dispatcher.DispatchOperation or System.ServiceModel.Dispatcher.ClientOperation and is therefore usually inserted by an operation behavior.

#region IParameterInspector Members
public void AfterCall(string operationName, object[] outputs, object returnValue, object correlationState)
    "IParameterInspector.AfterCall called for {0} with return value {1}.", 

public object BeforeCall(string operationName, object[] inputs)
  Console.WriteLine("IParameterInspector.BeforeCall called for {0}.", operationName);
  return null;

The following code example shows how the operation behavior attaches the parameter inspector to the runtime.

#region IOperationBehavior Members
public void AddBindingParameters(
  OperationDescription operationDescription, BindingParameterCollection bindingParameters
{ return; }

public void ApplyClientBehavior(OperationDescription operationDescription, ClientOperation clientOperation)
  clientOperation.ParameterInspectors.Add(new Inspector());

public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation)
  dispatchOperation.ParameterInspectors.Add(new Inspector());

public void Validate(OperationDescription operationDescription){ return; }
