Struct vs Class in .NET

Class are usually for large amounts of data, whereas structs are smaller, and often used when you want to group similar data together. Use a class when object identity is more important than value. Use a struct when the value contained by an instance is more important than instance identity.

Struct variables directly contain their values, so when you pass a struct instance as a parameter, it can be more expensive than passing an instance of a reference type, due to
the copying costs.


Here are just some of the differences between a struct and a class in .NET:
  • Classes are reference types and structs are value types. Since classes are reference type, a class variable can be assigned null, but we cannot assign null to a struct variable, since structs are value type.
  • You will always be dealing with reference to an object ( instance ) of a class. But you will not be dealing with references to an instance of a struct, you will be dealing directly with struct
  • Classes must be instantiated using the new operator, but structs can be instantiated without using the new operator.
  • Classes support inheritance.But there is no inheritance for structs, (structs don't support inheritance polymorphism ) . Note: both classes and structs support interface inheritance.
  • It is not mandatory to initialize all Fields inside the constructor of a class. But all the Fields of a struct must be fully initialized inside the constructor.
  • structs object is allocated in the stack, and the class object is allocated in the heap.
