Inherit two classes. Is this possible?

Hello,

Is it possible to have a class that inherits two other classes? Or
just one?
I am not able to find a syntax of a class that inherits two other
classes to have the properties of those two classes.

Thanks,
Miguel

No. C# does not support "multiple inheritance" (that's the phrase you'll
want to Google if you want more details on the subject.

In some cases, you can accomplish an equivalent design by declaring
multiple interfaces and having a single class implement them. You can
have multiple interface implementations in a class, just not multiple
inheritance.

Another good alternative is to use composition. That's often preferable
to inheritance anyway, and when dealing with two disparate classes you
want to include in a single class, composition can be a much cleaner way
to do it.

Not possible in C#.

You can only extend (inherit functionality) from one class, but
you can implement (inherit contract) from multiple interfaces.
