推荐答案

我个人喜欢拼出命名空间和程序集的别名。所以XML：

Personally I like to spell out namespaces and assemblies in aliases. So xml:

<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">

    <alias alias="Event_Interface" type="Mynamespace.IEventService, MyAssembly"/>
    <alias alias="EventService_Interface" type="Mynamespace.IEventServiceInformation, MyAssembly"/>
    <alias alias="Event_Class" type="Mynamespace.EventService, MyAssembly"/>

    <container>
      <register type="Event_Interface" mapTo="Event_Class"> 
        <lifetime type="singleton"/>
      </register>
      <register type="EventService_Interface" mapTo="Event_Class"> 
        <lifetime type="singleton"/>
      </register>
    </container>
</unity>

code：

code:

IUnityContainer container = new UnityContainer().LoadConfiguration();
