WebJan 22, 2010 · The short answer is yes, every implementing type will have to create its own backing variable. This is because an interface is analogous to a contract. All it can do is specify particular publicly accessible pieces of code that an implementing type must make available; it cannot contain any code itself. WebInterfaces are a form of programming-by-contract. From a certain viewpoint, one can argue that interfaces can be used to achieve a form of polymorphism in C#, but they are not polymorphism. Interface based programming is not limited to OO languages, and conversely OO languages do not require interfaces to function. tekken craig marduk x king
