What are the data types in C# language?

C# supports a variety of data types, including basic types such as integers, floating point numbers, characters, and Boolean values, as well as complex types such as strings, arrays, classes, and enumerations. Variable types can be specified using type specifiers (var, type name, generic type, nullable type), and implicit and explicit type conversions are supported.

Data types in C

#C# is a strongly typed language, which means that every variable The type must be specified at compile time. C# supports a wide range of data types, covering various needs from basic types to complex types.

Basic data types

• Integer types: byte, short, int, long, ulong
• Floating point types: float, double
• Character type: char
• Boolean type: bool
• null type: null

Other data types

• String (string): Store text data.
• Array (array): Stores an ordered collection of elements of the same type.
• Class (class): Custom data type that can encapsulate data and behavior.
• Structure (struct): lightweight data type, value type, stores related data.
• Enumeration (enum): A type that defines a set of named constants.
• Record (record): An immutable reference type with properties and constructors.
• Tuple (tuple): A set of values ​​of a fixed number and type.
• Generic (generic): A data type that can be customized using different types of parameters.
• Delegate (delegate): A reference pointing to a method or function.
• Pointer (pointer): The type that stores variable addresses.

Type specifiers

In C#, the type of a variable can be specified using one of the following type specifiers:

• var: Compiler inferred type (only for local variables).
• Type name: Specify an explicit type (for example, int, string).
• Generic type: Consists of a type name and a list of type parameters (for example, List).
• Nullable types: Use a question mark (?) to indicate that a variable can be null (for example, int?).

Data type conversion

C# provides implicit and explicit type conversion. Implicit type conversions are performed automatically at compile time, while explicit type conversions are performed using the cast operator.
