我想将自定义消息头添加到 myService 并且我已经点击了链接：

http://trycatch.me/adding-custom-message-headers-to-a-wcf-service-using-inspectors-behaviors/

我已经很好地配置了它，并且在服务器端 IServiceBehavior.ApplyDispatchBehavior 正在通过调试运行，我可以在 ServiceDescription.Endpoints[0].Behaviors 中看到我的自定义行为，但是当我运行 ServiceEndpointCollection endpoints = MetadataResolver.Resolve(descriptions, address, MetadataExchangeClientMode.MetadataExchange，客户端）；行为集合是空的，所以没有调用 IEndpointBehavior.ApplyDispatchBehavior 和 IEndpointBehavior.ApplyClientBehavior 函数 - 有人知道吗？这是我的配置文件：

<configuration>
  <system.serviceModel>
    <services>
      <service behaviorConfiguration="DefaultBehavior" name="MyService">
        <endpoint address="DatabaseService" behaviorConfiguration="MyCustomBehavior"

        <endpoint address="mex" binding="netTcpBinding"

            <add baseAddress="net.tcp://localhost/Services/SomeService" />
