[英]Need multiple inheritance functionality in C#. What am I doing wrong?
class UDPClient
{
}
class LargeSimulator
{
}
class RemoteLargeSimulatorClient : UDPClient, LargeSimulator
{
}
The saying goes, if you need multiple inheritance, your design is off. 俗话说,如果你需要多重继承,那么你的设计是不对的。
How would I get this done in C# without having to implement anything? 如何在C#中完成此操作而无需实现任何内容?
You can only inherent from a single base class in C#. 您只能从C#中的单个基类固有。 However, you can implement as many Interfaces as you'd like.
但是,您可以根据需要实现任意数量的接口。 Combine this fact with the advent of Extension Methods and you have a (hacky) work-around.
将此事实与扩展方法的出现相结合,您就可以进行(hacky)解决方案。
C# only allows single inheritance, though you can inherit from as many interfaces as you wish. C#只允许单继承,但您可以从任意数量的接口继承。
You could pick just one class to inherit from, and make the rest interfaces, or just make them all interfaces. 您可以只选择一个要继承的类,然后创建其余的接口,或者只创建所有接口。
You could also chain your inheritence like so: 你也可以像这样链接你的继承:
class UDPClient
{
}
class LargeSimulator : UDPClient
{
}
class RemoteLargeSimulatorClient : LargeSimulator
{
}
To get multiple inheritance the way you want it, you need to make your UDPClient and LargeSimulator interface
instead of class
. 要以您希望的方式获得多重继承,您需要创建UDPClient和LargeSimulator
interface
而不是class
。
Class multiple inheritance isn't possible in C# C#中不可能进行类多重继承
One possible substitute for multiple inheritance is mixins. mixin的一种可能替代是多重继承。 Unfortunately C# doesn't have those either, but workarounds are possible.
不幸的是,C#也没有这些,但可以使用变通方法。 Most rely on the use of extension methods (as a previous answerer suggested).
大多数人依赖于扩展方法的使用(如之前的回答者所建议)。 See the following links:

The short answer: Multiple inheritance is not allowed in C#. 简短的回答:C#中不允许多重继承。 Read up on interfaces: http://msdn.microsoft.com/en-us/library/ms173156.aspx

The slightly longer answer: Maybe some other design pattern would suit you, like the strategy pattern, etc. Inheritance isn't the only way to achieve code reuse. 稍微长一点的回答:也许其他一些设计模式适合你,比如策略模式等。继承不是实现代码重用的唯一方法。
interface ILARGESimulator
{
}
interface IUDPClient
{
}
class UDPClient : IUDPClient
{
}
class LargeSimulator : ILARGESimulator
{
}
class RemoteLargeSimulatorClient : IUDPClient, ILargeSimulator
{
private IUDPClient client = new UDPClient();
private ILARGESimulator simulator = new LARGESimulator();
}
Unfortunately you will need to write wrapper methods to the members. 不幸的是,您需要为成员编写包装器方法。 Multiple inheritance in C# does not exist.
C#中的多重继承不存在。 You can however implement multiple interfaces.
但是,您可以实现多个接口。
