 Re: Inherit multiple interfaces
I'll make the answer short : no.
Quoted from MSDN: Quote:
No Multiple-Inheritance in .NET
You could try creating a CreditCheckableSalesOrder type that derives from SalesOrder. Some order types would derive from ConfirmableSalesOrder, and some from CreditCheckableSalesOrder, but what about those that need both confirmation and credit checks? One of the limitations on inheritance in the .NET Framework is that a type can only be derived from one base type.
You can't have order types that derive from both ConfirmableOrder and CreditCheckableOrder. This may seem like an arbitrary or misguided limitation, but there are good reasons for it. Multiple-inheritance is supported in C++. However, just about all the other modern object-oriented languages, including Java, have chosen not to allow multiple-inheritance. (Some advanced languages, such as Eiffel, have attempted to work out the kinks of multiple inheritance, and Eiffel for Microsoft .NET even provides the appearance of multiple inheritance within Microsoft .NET.)
The biggest problem with multiple-inheritance is that it allows for ambiguity when the compiler needs to find the correct implementation of a virtual method.
