Supported value types in C# include integers, floating point, Boolean, characters, and enumeration types; reference types include classes, interfaces, arrays, and strings. Value types are stored on the stack, and when copied, a copy is created, while reference types are stored on the heap, and when copied, another reference to the original data is created.

What types of variables are included in the C# language and what are their characteristics?

Variable Types in C

#In C#, variables are used to store data. The following are the different types of variables supported by C#:

Value type

  • ##Integer type: byte, sbyte, short , ushort, int, uint, long, ulong

      stores integers and numbers within a specific range.
  • Floating point types: float, double

      Storage decimals and larger number ranges.
  • Boolean type: bool

      Stores a Boolean value (true or false).
  • Character type: char

      Stores a single character.
  • Enumeration type: enum

      A constant that defines a set of related values.

Reference type

  • Class: A blueprint for a specific object, containing its data and methods .
  • Interface: Defines the methods that an object must implement.
  • Array: Stores a collection of elements of the same type.
  • String: Stores text characters.

Type characteristics

Value type:

    Stored on the stack.
  • Create a new copy when copying. When
  • is modified, the original value will not be affected.

Reference type:

    Stored on the heap.
  • The reference variable points to the actual data on the heap.
  • Copying a reference variable does not copy the data, but creates another reference to the original data. When
  • is modified, it will also affect the original data.
