public string ReplyAction { get; set; }

member this.ReplyAction : string with get, set

Public Property ReplyAction As String

属性值

String

用于答复消息的 SOAP 操作的值。

例外

ArgumentNullException

ReplyAction 为 null。

示例

下面的示例演示了一个服务，该服务使用 Action 和 ReplyAction 属性显式控制输入和输出（或答复）消息的 SOAP 操作。 它还使用 Name 属性声明在元数据中公开的操作名称。

using System;
using System.Collections.Generic;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.Text;

namespace Microsoft.WCF.Documentation
{
  [ServiceContract(Namespace="http://Microsoft.WCF.Documentation")]
  public interface ISampleService{

    [OperationContract(
      Action="http://Microsoft.WCF.Documentation/OperationContractMethod",
      Name="OCAMethod",
      ReplyAction="http://Microsoft.WCF.Documentation/ResponseToOCAMethod"
    )]
    string SampleMethod(string msg);

    [OperationContractAttribute(Action = "*")]
    void UnrecognizedMessageHandler(Message msg);
  }

  class SampleService : ISampleService
  {
    public string  SampleMethod(string msg)
    {
      Console.WriteLine("Called with: {0}", msg);
        return "The service greets you: " + msg;
    }

    public void UnrecognizedMessageHandler(Message msg)
    {
      Console.WriteLine("Unrecognized message: " + msg.ToString());
    }
  }
}

Imports System.ServiceModel
Imports System.ServiceModel.Channels
Imports System.Text

Namespace Microsoft.WCF.Documentation
  <ServiceContract(Namespace:="http://Microsoft.WCF.Documentation")> _
  Public Interface ISampleService

        <OperationContract(Action:="http://Microsoft.WCF.Documentation/OperationContractMethod", _
                           Name:="OCAMethod", ReplyAction:="http://Microsoft.WCF.Documentation/ResponseToOCAMethod")> _
        Function SampleMethod(ByVal msg As String) As String

    <OperationContractAttribute(Action := "*")> _
    Sub UnrecognizedMessageHandler(ByVal msg As Message)
  End Interface

  Friend Class SampleService
      Implements ISampleService
    Public Function SampleMethod(ByVal msg As String) As String Implements ISampleService.SampleMethod
      Console.WriteLine("Called with: {0}", msg)
         Return "The service greets you: " & msg
    End Function

    Public Sub UnrecognizedMessageHandler(ByVal msg As Message) Implements ISampleService.UnrecognizedMessageHandler
      Console.WriteLine("Unrecognized message: " & msg.ToString())
    End Sub
  End Class
End Namespace

注解

除指定答复消息操作标头的特定值以外，还可以指定字符串“*”（星号）。 在服务中指定星号指示 WCF 不向消息添加回复操作，如果直接针对消息进行编程，这非常有用。 在客户端应用程序中指定星号指示 WCF 不验证回复操作。
