WHAT IS interface in asp net?

Net. Interface is a type which contains only the signatures of methods, delegates or events, it has no implementation. Implementation of the methods is done by the class which implements the interface. Interface is a contract that defines the signature of the functionality.Click to see full answer. Consequently, what is the interface in C#?An INTERFACE in C# is a type definition similar to a class, except that it purely represents a contract between an object and its user. It can neither be directly instantiated as an object, nor can data members be defined. So, an interface is nothing but a collection of method and property declarations.Also Know, what is an interface? An interface is a reference type in Java. It is similar to class. It is a collection of abstract methods. A class implements an interface, thereby inheriting the abstract methods of the interface. Along with abstract methods, an interface may also contain constants, default methods, static methods, and nested types. Consequently, wHAT IS interface in C# and why it is used? First and foremost, interfaces in C# are a means to get around the lack of multiple inheritances in C#, meaning you cannot inherit from multiple classes but you can implement multiple interfaces. An interface contains no implementation, only the signatures of the functionality the interface provides.What is the use of interface?It is used to achieve total abstraction. Since java does not support multiple inheritance in case of class, but by using interface it can achieve multiple inheritance . It is also used to achieve loose coupling.
