切换回组装关系图并创建一个选择器组件。
Switch back to your assembly diagram and create a Selector component.
选择器的目标可以是相同模块的组装关系图中的组件，或另一个模块的导出。
The destination of a selector can be a component inside the assembly diagram of the same module or an export of another module.
这意味着，在前一个示例中，您不必重新部署业务流程，以修改您希望通过选择器分派的组件。
This means that in the previous example, you would not have to redeploy the business process to modify the components you want to dispatch to through the selector.
本文包含这种语音应用程序的部件清单，但您首先想知道的是这个选择器的设计流以及不同的组件如何交互。
This article includes a listing of the parts of such a voice application, but first you will want to know the flow of design of this selector and how the different components interact.
现在，您可以定义选择器，以便将服务调用路由到正确的组件。
Now, you can define the selector so that the service call gets routed to the correct component. In the next steps, you specify the selection criteria, which is the value of the applyDate variable
在本部分中，通过修改业务流程的调用活动，可使您的应用程序更灵活，以便它可以调用选择器，而不是指定的组件。
In this section, you make the application more flexible by modifying the invoke activity of the business process so that it calls the selector, rather than a specific component.
选择器的基本用途是进行简单的分派，这意味着您可以将服务调用的目标从一个组件或导入动态地重新路由到或导入另一个组件。
A basic use of a selector is for simple dispatch, which means you can dynamically reroute the destination of a service call from one component or import to another.
您可以从任何面向服务的组件调用选择器。
You can call a selector from any of your service-oriented components.
选择器是一种分派模式，用于动态确定在运行时调用哪一个组件的实现。
A selector is a dispatch pattern you use to dynamically determine which implementation of a component to invoke at runtime.
换句话说，选择器在运行时可以将服务调用动态地重新路由到任何其他组件。
In other words, a selector can dynamically re-route a service call to any other component at runtime.
负载均衡器可以与服务器安放在同一台机器上，因为服务器是用来装载均衡请求的。这种并置适合于负载均衡器的分派器和站点选择器(Site Selector)组件。
Load Balancer can reside on the same machine as a server for which it is load balancing requests; this collocation applies to the Dispatcher and Site Selector components of load Balancer.
此操作将返回到“继承选择器”对话框，现在其中列出了该组件及其所在的项目。
This returns you to the Inheritance Picker dialog box, where the component is now listed, along with the project in which it is located.
