C# : What is the difference between a struct and a class in C#

Answer:

Class and struct both are the user defined data type but have some major difference:

Struct

• The struct is value type in C# and it inherits from System.Value Type.
• Struct is usually used for smaller amounts of data.
• Struct can’t be inherited to other type.
• A structure can't be abstract.
• No need to create object by new keyword.
• Do not have permission to create any default constructor.

Class

• The class is reference type in C# and it inherits from the System.Object Type.
• Classes are usually used for large amounts of data.
• Classes can be inherited to other class.
• A class can be abstract type.
• We can’t use an object of a class with using new keyword.
• We can create a default constructor.
