IParameterInspector.AfterCall(String, Object[], Object, Object) 方法

定義

命名空間:

System.ServiceModel.Dispatcher

組件:

System.ServiceModel.Primitives.dll

套件:

System.ServiceModel.Primitives v8.1.0

來源:

IParameterInspector.cs

當用戶端呼叫已傳回後，且在服務回應傳送之前進行呼叫。

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)

參數

operationName

String

叫用的作業名稱。

outputs

Object[]

任何輸出物件。

returnValue

Object

作業的傳回值。

correlationState

Object

從 BeforeCall(String, Object[]) 方法傳回的任何相互關聯狀態，或是 null。

範例

下列程式碼範例會示範 IParameterInspector 實作：

• 當服務已經將回應還原序列化或是用戶端已經將要求序列化之後，將作業名稱和傳回值寫入至主控台。

• 在用戶端上還原序列化回應之後，或在服務上序列化回應之後，將作業名稱寫入至主控台。

#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

下列程式碼範例會示範如何使用 System.ServiceModel.Description.IOperationBehavior、System.ServiceModel.Description.IEndpointBehavior 或 System.ServiceModel.Description.IServiceBehavior 來插入 IParameterInspector 物件。

備註

從用戶端進行傳出呼叫時會先叫用偵測器，然後序列化要求內容，並將結果傳送給服務。 在完成還原序列化回應之後，但在傳回值分派給 Proxy 方法之前，也會呼叫這個偵測器。

對服務進行傳入呼叫時，會在完成還原序列化參數之後，但在結果分派至服務作業之前叫用偵測器。
