为什么c#不支持多重继承，而c++支持多重继承？怎么可能？ C++如何支持？

首先，一个小修正：C# 确实支持多个接口继承。它不支持多个实现继承。
不支持 MI 的两个重要原因是：
很可能您可以通过多接口继承执行您想要的操作。
它给编译器实现增加了很多复杂性。
在我看来，在许多情况下，语言中多重继承的可用性导致该功能经常被滥用。当诸如组合之类的东西也可以做同样的事情时，单继承已经不必要地融入了许多类层次结构中。
First, a small correction: C# does support multiple interface inheritance. It doesn't support multiple implementation inheritance.
The two big reasons MI isn't supported are:
Chances are good that you can do what you want with multiple interface inheritance anyway.
It adds a lot of complexity to the compiler implementation.
IMO, in many cases, the availability of multiple inheritance in a language causes that feature to be frequently abused. Single inheritance already gets wedged into a lot of class hierarchies unnecessarily when something like composition would do just as well.
从有关 C# 常见问题的 MSDN 博客中，您可以找到此答案。还有这个高度评价的 Stack Overflow 问题。
