Is an interface a value type or reference type?

Is an interface a value type or reference type?

Do interface variables have value-type or reference-type semantics? Interfaces are implemented by types, and those types are either value types or reference types. Obviously, both int and string implement IComparable , and int is a value type, and string is a reference type.

Is an interface type A reference type?

When you define a new interface, you are defining a new reference data type. If you define a reference variable whose type is an interface, any object you assign to it must be an instance of a class that implements the interface. …

Is interface reference type in C#?

In C#, classes and interfaces are reference types. Variables of reference types store references to their data (objects) in memory, and they do not contain the data itself.

What is value type and reference type in C#?

The Types in . A Value Type holds the data within its own memory allocation and a Reference Type contains a pointer to another memory location that holds the real data. Reference Type variables are stored in the heap while Value Type variables are stored in the stack.

What is the reference type in C#?

The Reference type variable is such type of variable in C# that holds the reference of memory address instead of value. class, interface, delegate, array are the reference type. When you create an object of the particular class with new keyword, space is created in the managed heap that holds the reference of classes.

What is interface type in C#?

Interfaces define properties, methods, and events, which are the members of the interface. Interfaces contain only the declaration of the members. Some of the interface types in C# include. IEnumerable − Base interface for all generic collections. IList − A generic interface implemented by the arrays and the list type.

Is value type C#?

Structs are value types, while classes are reference types, and the runtime deals with the two in different ways. When a value-type instance is created, a single space in memory is allocated to store the value. Primitive types such as int, float, bool and char are also value types, and work in the same way.

What are value types in C #?

Value types include simple types (such as int, float, bool, and char), enum types, struct types, and Nullable value types. Reference types include class types, interface types, delegate types, and array types.
