[英]generic base class that implements interface
How can I declare my Basepage class in an asp.net webforms project to also implement IBasePage? 如何在asp.net webforms项目中声明我的Basepage类以实现IBasePage?
public abstract class BasePage<T> : Page where T : class
{
}
and the interface 和界面
public interface IBasePage
{
UserProfile UserProfile { get;}
bool IsStreamingAdmin {get;}
int? EmplId {get;}
}
my ultimate goal is to be able to write code this like: 我的最终目标是能够编写如下代码:
IBasePage page = HttpContext.Current.Handler as IBasePage;
if (page.IsStreamingAdmin)
{
//do something here....
}
你的问题对我来说并不完全清楚,但你不能这样做:
public abstract class BasePage<T> : Page, IBasePage where T : class { }
public abstract class BasePage<T> : Page, IBasePage where T : class { }
If your class implements all the methods defined in the interface
your code is able to compile and you will be able to call an instance
of your abstract class. 如果您的类实现了interface
定义的所有方法,您的代码就可以编译,并且您将能够调用抽象类的instance
。
Calling page.IsStreamingAdmin
will result in returning the value of the class you have an instance of. 调用page.IsStreamingAdmin
将返回您拥有实例的类的值。
