Array<T>

Struct · built-in type

struct Array<T>

An array, T[]: a fixed number of values, created with new T[n] (zeroed) or new T[] { a, b } / [a, b].

var squares = new int[10];
for (var i = 0; i < squares.Length; i += 1)
    squares[i] = i * i;
foreach (var s in squares[1..4])     // a Slice<int>: 1, 4, 9
    Console.WriteLine(s);

Arrays have reference semantics: assigning one shares the elements (reference counted); Array.Clone copies. a[i] checks the index (a panic outside of 0 to Length - 1), a[^1] is the last element, a[i..j] a Slice (a view). A List grows; an array does not.

Fields

Length	The number of elements.

Length

int Length

The number of elements.

Static methods

Name	Description
Copy	Copies count elements of source from sourceIndex to destination from destinationIndex (the ranges may overlap).

Copy

static void Copy(T[] source, int sourceIndex, T[] destination, int destinationIndex, int count)

Copies count elements of source from sourceIndex to destination from destinationIndex (the ranges may overlap).

Panics when a range is not inside of its array.

Methods

Name	Description
