使用VS快速将类方法封装成Web服务

在项目中有时需要将整个业务逻辑类下面的方法封装成Web服务，由于只是简单的封装，在Web服务的后台代码中不会写上任何逻辑，这时我们就需要Web服务提供的方法与类下面提供的方法相同，这是就考虑到使用接口。申明一个接口，然后让业务逻辑类和Web服务类都实现该接口即可。这里我们就要用到VS中一个很好的功能：重构！

假设我们现在有一个业务逻辑类HelloLogic用于处理一些业务逻辑，如：

<div style="border-right: #cccccc 1px solid; padding-right: 5px; padding-left: 4px; font-size: 13px; border-top: #cccccc 1px solid; padding-bottom: 4px; border-left: #cccccc 1px solid; width: 98%; word-break: break-all; padding-top: 4px; border-bottom: #cccccc 1px solid; background-color: #eeeeee">
