<object id="UserDao" type="SpringSample.UserDao, SpringSample"/>
<object id="UserService" type="SpringSample.UserService, SpringSample" >
<property name="UserDao" ref="UserDao"/>
</object>

IApplicationContext ctx = ContextRegistry.GetContext();
IUserService userService = ctx.GetObject("UserService") as IUserService;
Console.WriteLine(userService.GetName());
