c# - 未调用 CreateBehavior()

Question

我已提及Why isn't my custom WCF behavior extension element type being found? ;但以下是一个不同的问题

我有一个自定义BehaviorExtensionElement，如下所示。运行服务时，它的构造函数被调用。但是它不会调用 CreateBehavior() 方法。因此我的 IEndpointBehavior 没有被构造。

服务工作正常，没有任何异常。

知道为什么不调用 CreateBehavior() 方法吗？

注意:我正在从 Visual Studio 2010 运行 Web 服务应用程序。

配置

  <endpointBehaviors>
    <behavior name="EndpointBehavior">
      <XMessageValidator validateRequest="True" validateReply="true" validateWSE="true">
      </XMessageValidator>
    </behavior>
  </endpointBehaviors>


 //Other config entries

<extensions>
  <behaviorExtensions>
    <add name="XMessageValidator" type="MessageInspectorLibrary.ValidationBehaviorExtensionElement, MessageInspectors, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
  </behaviorExtensions>
</extensions>

行为扩展元素

public class ValidationBehaviorExtensionElement : BehaviorExtensionElement
{
    public ValidationBehaviorExtensionElement()
    {
        //Constructor
    }

    public override Type BehaviorType 
    { 
        get
        {
            return typeof(MessageValidationBehavior);
        } 
    }

    protected override object CreateBehavior()
    {
        throw new Exception("My CreateBehavior");
        return null;

    }

    [ConfigurationProperty("validateRequest", DefaultValue = false, IsRequired = false)]
    public bool ValidateRequest
    {
        get { return (bool)base["validateRequest"]; }
        set { base["validateRequest"] = value; }
    }

    [ConfigurationProperty("validateReply", DefaultValue = false, IsRequired = false)]
    public bool ValidateReply
    {
        get { return (bool)base["validateReply"]; }
        set { base["validateReply"] = value; }
    }

    [ConfigurationProperty("validateWSE", DefaultValue = false, IsRequired = false)]
    public bool ValidateWSE
    {
        get { return (bool)base["validateWSE"]; }
        set { base["validateWSE"] = value; }
    }

}

IEndpointBehavior

public class MessageValidationBehavior : IEndpointBehavior
{
    XmlSchemaSet schemaSet; 
    bool validateRequest; 
    bool validateReply;
    bool validateWSE;

    public MessageValidationBehavior(XmlSchemaSet schemaSet, bool inspectRequest, bool inspectReply, bool inspectWSE)
    {
        this.schemaSet = schemaSet;
        this.validateReply = inspectReply;
        this.validateRequest = inspectRequest;
        this.validateWSE = inspectWSE;

        throw new Exception("My MessageValidationBehavior");
    }


    #region IEndpointBehavior Members

    public void AddBindingParameters(ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime)
    {
        ValidationMessageInspector inspector = new ValidationMessageInspector(schemaSet, validateRequest, validateReply, validateWSE, true);
        clientRuntime.MessageInspectors.Add(inspector);
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
    {
        ValidationMessageInspector inspector = new ValidationMessageInspector(schemaSet, validateRequest, validateReply, validateWSE, false);
        endpointDispatcher.DispatchRuntime.MessageInspectors.Add(inspector);
    }

    public void Validate(ServiceEndpoint endpoint)
    {
    }

    #endregion
}

Answer 1

注意:正如我在问题中所说，即使没有以下更改，该服务也会给出正确的响应消息。此外，还调用了 ValidationBehaviorExtensionElement 类。

解决方案

当我正确设置服务名称(即namespace.servicename)时，会调用CreateBehavior()。

我的理解是 - BehaviorExtension 的创建与服务名称无关。但仅当服务名称正确时才会创建 EndPointBehavior。如果您对此有一些想法/引用，欢迎提供更多详细信息。

以下是完整的 serviceModel 配置
