托管代码中MI的替代方案??? [英] Alternatives to MI in managed code???
问题描述
由于托管代码（C ++ / C＃/等）不支持多重继承，
任何人都有合适的解决方法吗？对我来说，这是.NET子系统的严重*限制。
我知道*接口*，但它们适用于类的* USER *，而不是
* IMPLEMENTOR *。我也知道在一个类中添加多个类，然后创建包装器（更多的是HAS-A实现而不是IS-A），但是那是
繁琐又多为班级用户更多，并且不支持多态。
这是一个例子：
假设我有一个没有接口的非平凡类（它纯粹是一个
功能组件）。 *没有办法*在没有更改基类本身的情况下将界面（ala表格）添加到
该组件。

Since managed code (C++/C#/etc.) doesn''t support multiple inheritance, does
anyone have a suitable work-around? To me, this is a *serious* limitation of
the .NET subsystem.
I''m aware of *interfaces*, but they are for the *USER* of the class, not the
*IMPLEMENTOR*. I''m also aware of adding multiple classes to a class and then
creating wrappers (more of a HAS-A implementation than IS-A), but that is
tedious and again is more for the class user and doesn''t support polymorphism.
Here is an example:
Suppose I have a non-trivial class that has no interface (it is purely a
functional component). There is *no way* to add an interface (ala forms) to
that component without changing the base class itself.

为什么不继承自System.Windows.Form？

正如我所说：
> Why not inherit from System.Windows.Form?
As I said:
有* no方式*在不更改基础类本身的情况下向该组件添加
接口（ala表单）。
There is *no way* to add an
interface (ala forms) to that component without changing the base
class itself.
我无法访问基础修改它的继承类。

I don''t have access to the base class to modify its inheritance.

为什么不从System继承。 Windows.Form？

如果您可以访问派生类，则从中派生一个新类和
System.Windows.Form。

If you have access to the derived class, derive a new class from it and
System.Windows.Form.
