IOperationBehavior.ApplyDispatchBehavior 方法

定义

命名空间:
System.ServiceModel.Description
程序集:
System.ServiceModel.dll, System.ServiceModel.Primitives.dll
程序集:
System.ServiceModel.dll

跨操作实现服务的修改或扩展。

public:
 void ApplyDispatchBehavior(System::ServiceModel::Description::OperationDescription ^ operationDescription, System::ServiceModel::Dispatcher::DispatchOperation ^ dispatchOperation);
public void ApplyDispatchBehavior(System.ServiceModel.Description.OperationDescription operationDescription, System.ServiceModel.Dispatcher.DispatchOperation dispatchOperation);
abstract member ApplyDispatchBehavior : System.ServiceModel.Description.OperationDescription * System.ServiceModel.Dispatcher.DispatchOperation -> unit
Public Sub ApplyDispatchBehavior (operationDescription As OperationDescription, dispatchOperation As DispatchOperation)

参数

operationDescription
OperationDescription

正在检查的操作。 仅用于检查。 如果修改了操作说明，则结果未定义。

dispatchOperation
DispatchOperation

公开操作 operationDescription的自定义属性的运行时对象。

示例

下面的代码示例演示在操作上调用检查器时写入控制台的实现 System.ServiceModel.Dispatcher.IParameterInspector 。 此自定义项只能附加到该System.ServiceModel.Dispatcher.DispatchOperation自定义项，System.ServiceModel.Dispatcher.ClientOperation因此通常由操作行为插入。

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

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

#Region "IParameterInspector Members"
    Public Sub AfterCall(ByVal operationName As String, ByVal outputs() As Object, ByVal returnValue As Object, _
                         ByVal correlationState As Object) Implements IParameterInspector.AfterCall
        Console.WriteLine("IParameterInspector.AfterCall called for {0} with return value {1}.", _
                          operationName, returnValue.ToString())
    End Sub

    Public Function BeforeCall(ByVal operationName As String, ByVal inputs() As Object) As Object Implements _
    IParameterInspector.BeforeCall
        Console.WriteLine("IParameterInspector.BeforeCall called for {0}.", operationName)
        Return Nothing
    End Function

下面的代码示例演示如何操作行为将参数检查器附加到运行时。

#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; }

#Region "IOperationBehavior Members"
    Public Sub AddBindingParameters(ByVal operationDescription As OperationDescription, _
                                    ByVal bindingParameters As BindingParameterCollection) Implements _
                                    IOperationBehavior.AddBindingParameters
        Return
    End Sub

    Public Sub ApplyClientBehavior(ByVal operationDescription As OperationDescription, ByVal _
                                   clientOperation As ClientOperation) Implements IOperationBehavior.ApplyClientBehavior
        clientOperation.ParameterInspectors.Add(New Inspector())
    End Sub

    Public Sub ApplyDispatchBehavior(ByVal operationDescription As OperationDescription, ByVal dispatchOperation As  _
                                     DispatchOperation) Implements IOperationBehavior.ApplyDispatchBehavior
        dispatchOperation.ParameterInspectors.Add(New Inspector())
    End Sub

Public Sub Validate(ByVal operationDescription As OperationDescription) Implements IOperationBehavior.Validate
    Return
End Sub

注解

实现用于 ApplyDispatchBehavior 查看所有消息或针对特定操作查看、修改或扩展服务运行时的方法。 有关可在服务应用程序中执行的操作的详细信息，请参阅 System.ServiceModel.Dispatcher.DispatchRuntime 和 System.ServiceModel.Dispatcher.DispatchOperation。

如果行为仅用于客户端应用程序，则建议 ApplyDispatchBehavior 该方法引发 NotImplementedException 异常。
