Enum types can have instance methods and a constructor (the arguments of which can be specified separately for each enum value). All enum types implicitly extend the Enum abstract class. An enum type cannot be instantiated directly. [8] Internally, each enum value contains an integer, corresponding to the order in which they are declared in the ...
C# has and allows pointers to selected types (some primitives, enums, strings, pointers, and even arrays and structs if they contain only types that can be pointed [14]) in unsafe context: methods and codeblock marked unsafe. These are syntactically the same as pointers in C and C++. However, runtime-checking is disabled inside unsafe blocks.
In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also supported.
Replace array element at index with the float32 value on the stack. Object model instruction 0xA1 stelem.r8: Replace array element at index with the float64 value on the stack. Object model instruction 0xA2 stelem.ref: Replace array element at index with the ref value on the stack. Object model instruction 0x7D stfld <field>
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
Enumerations in C# are implicitly derived from the Enum type that again is a value type derivative. The value set of a C# enumeration is defined by the underlying type that can be a signed or unsigned integer type of 8, 16, 32 or 64 bits. The enumeration definition defines names for the selected integer values.
The term is commonly used in mathematics and computer science to refer to a listing of all of the elements of a set. The precise requirements for an enumeration (for example, whether the set must be finite, or whether the list is allowed to contain repetitions) depend on the discipline of study and the context of a given problem.
A list may contain the same value more than once, and each occurrence is considered a distinct item. A singly-linked list structure, implementing a list with three integer elements. The term list is also used for several concrete data structures that can be used to implement abstract lists, especially linked lists and arrays.
