What are the C# value types?

The value type is the data type stored in the stack and directly contains the value itself. C# value types include boolean, character, integer, floating point and decimal. Value types have features such as value semantics, stack allocation, immutability, and no support for null values.

C# Value type

The value type is a data type stored on the stack. Unlike reference types, value types do not refer to other memory locations but directly contain the value itself.

C# Value type list:

• Boolean type (bool): Boolean value of true or false.
• Character type (char): Unicode character.
• Integer type (sbyte, byte, short, ushort, int, uint, long, ulong): signed or unsigned integer.
• Floating point type (float, double): Floating point value.
• Decimal type (decimal): High-precision decimal value.

Value type characteristics:

• Value semantics: Value types use value semantics, which means that any Modifications will affect the original value.
• Stack allocation: Value types are stored on the stack, which is a faster memory allocation mechanism than heap allocation.
• Immutable: Once a value type is created, its value is immutable.
• Does not support null values: The value type does not support null values.
