一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。

在客户端调用返回之后、服务响应发送之前调用。

public:
 void AfterCall(System::String ^ operationName, cli::array <System::Object ^> ^ outputs, System::Object ^ returnValue, System::Object ^ correlationState);

public void AfterCall (string operationName, object[] outputs, object returnValue, object correlationState);

abstract member AfterCall : string * obj[] * obj * obj -> unit

Public Sub AfterCall (operationName As String, outputs As Object(), returnValue As Object, correlationState As Object)

参数

operationName: String

所调用的操作的名称。

outputs: Object[]

任何输出对象。

returnValue: Object

操作的返回值。

correlationState: Object

从 BeforeCall(String, Object[]) 方法返回的任何关联状态，或 null。

示例

下面的代码示例演示了 IParameterInspector 实现：

在服务反序列化响应或客户端序列化请求之后，将操作名称和返回值写入控制台。
在客户端反序列化响应或服务序列化响应之后，将操作名称和返回值写入控制台。

#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

注解

对于来自客户端的出站调用，该检查器是在请求内容序列化并发送到服务之前调用的。同时，还会在响应消息被反序列化之后，但在将返回值调度到代理方法之前，调用该检查器。

对于到服务的入站调用，该检查器是在反序列化参数之后、但在这些参数调度到服务操作之前调用的。
