Hi experts,
Suppose I wanna design a program for a faculty,I should consider students,employees,...
but here someone could be students and employee together...
I think here I need multiple inheritance but there is no multiple inheritance in C# so I designed it like this,
an interface for students,a class for students,
an interface for employees,a class for employees,
another class that implements student interface and employee interface,(for those are student and employee)
I dont know whether there are better ways for this,
Thanks in advance.

Interfaces are your only choice for multiple inheritance in C#.

Kep.

well,I know interfaces are used for declarations of some procedures or properties,if I dont use interfaces I can just write my implementations in classes ... can you clarify your meaning more?
I found another design,for example,
I can have an interface for students and a StudentClass implements StudentInterface and also an interface for employees and a EmployeeClass implements EmployeeInterface,
then I derive a class(StudentEmployee) from StudentClass and implement EmployeeInterface.I think this could be a better approach.

I think I got my answer,we use interfaces for reducing code-using and also for different implementations,
(when you want to write a program for a teacher just knows PASCAL!,about two hours we were struggling to teach our dear teacher what could be an interface!what could be an inheritance!what could be a ....)
