Hi,
Structures are value types and the classes are reference types.
Classes are usually used for large amounts of data, whereas structs are usually used for smaller amounts of data.
Classes can be inherited whereas structures not.
A structure couldn't be null like a class.
A structure couldn't have a destructor such as a class.
A structure can't be abstract, a class can.
You cannot override any methods within a structure except the following belonging to the type object:
1. Equals()
  GetHashCode()
  GetType()
  ToString()
  
  And the other polymorphism technique used for structures is implementing interfaces.
2. Declared events within a class are automatically locked and then they are thread safe, in contrast to the structure type where events can't be locked

Hello,
Basic main difference , class default access specifier is private , struct default is public
where to use
Oops concept generally we use the class , struct where to use ( ex: you can use in the socket programming to transfer data)

Main deference is:-

class is a reference type.

struct is a value type.
