contains

public bool contains(T value)

true if the element is in the array and false otherwise.

Parameters

value

The element to find in the array.

Checks if an element is in the array. By default, this check uses value equality for primitive data types and reference equality otherwise. This behavior can be overridden by implementing the System.ILike<T> interface.

This method does not mutate the array.
