如何添加自定義PersistenceIOParticipant使用的web.config

我想，因爲我使用的網絡服務器託管.xamlx服務如何添加自定義PersistenceIOParticipant使用的web.config

host.WorkflowExtensions.Add(new HiringRequestInfoPersistenceParticipant());

複製下面使用web.config中的功能的web服務器託管.xamlx服務

我已經嘗試了以下，我已經能夠收集搜索，但沒有滿意。

<extensions> 
     <behaviorExtensions> 
      <add name="sqlTracking" 
       type="ApprovalService.Persistence.HiringRequestInfoPersistenceParticipant, ApprovalService.Persistence" /> 
     </behaviorExtensions> 
    </extensions>

任何幫助將深表感謝。

這裏是我的web.config更新

<system.serviceModel> 
    <extensions> 
     <behaviorExtensions> 
      <add name="sqlTracking" 
       type="ApprovalService.HiringInfoElement, ApprovalService"/> 
     </behaviorExtensions> 
    </extensions> 
    <services> 
     <service name="ApprovalService" behaviorConfiguration="ApprovalServiceBehavior"> 
     </service> 
    </services> 
    <behaviors> 
     <serviceBehaviors> 
      <behavior name="ApprovalServiceBehavior"> 
       <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> 
       <serviceMetadata httpGetEnabled="true" /> 
       <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> 
       <serviceDebug includeExceptionDetailInFaults="false" /> 
       <sqlWorkflowInstanceStore connectionStringName="WorkflowPersistence" /> 
       <workflowIdle timeToPersist="0" timeToUnload="0:05:0"/> 
       <sqlTracking/> 
      </behavior> 
     </serviceBehaviors> 
    </behaviors> 
</system.serviceModel>

這一切都編譯並運行，但自定義持久化對象從來沒有得到的調用。

您是否已將sqlTracking行爲添加到服務行爲部分？

下面是一個工作示例

public class StringWriterElement : BehaviorExtensionElement 
{ 
    public override Type BehaviorType 
    { 
     get { return typeof(StringWriterBehavior); } 
    } 

    protected override object CreateBehavior() 
    { 
     return new StringWriterBehavior(); 
    } 
} 

public class StringWriterBehavior : IServiceBehavior 
{ 
    public void ApplyDispatchBehavior(ServiceDescription serviceDescription, 
                    ServiceHostBase serviceHostBase) 
    { 
     var host = (WorkflowServiceHost)serviceHostBase; 
     host.WorkflowExtensions.Add<TextWriter>(() => new StringWriter()); 
    } 
}

而且在web.config：

<system.serviceModel> 
    <extensions> 
    <behaviorExtensions> 
     <add name="stringWriter" 
      type=" MyWorkflowService.StringWriterElement, MyWorkflowService"/> 
    </behaviorExtensions> 
    </extensions> 
    <services> 
    <service name="OrderWorkflow「 
      behaviorConfiguration="OrderWorkflowBehavior"> 
    </service> 
    </services> 
    <behaviors> 
    <serviceBehaviors> 
     <behavior name="OrderWorkflowBehavior"> 
     <serviceMetadata httpGetEnabled="True"/> 
     <stringWriter /> 
     </behavior> 
    </serviceBehaviors> 
    </behaviors> 
</system.serviceModel>

感謝莫里斯，你能進一步解釋一下呢？我的HiringRequestInfoPersistenceParticipant繼承自PersistenceIOParticipant。我會簡單地用我的HiringRequestInfoPersistenceParticipant替換你的stringWriter嗎？我想WF會發現它是一個PersistenceParticipant並且恰當地使用它？ – Steven

是的，這是正確的。 – Maurice

我已經添加了一個更新的配置文件，但是我的持久對象永遠不會被調用。我可以看到工作流本身得到的持久化到InstancesTable中的實例存儲，但我的自定義持久性代碼似乎永遠不會被調用。我感謝你的繼續幫助。 – Steven
