Differences and relationships between array, arraylist, and list in C #

Array: fixed-length memory segments

Arraylist: it can be understood that the memory can be dynamically increased.

List is a type of generic linked list. It solves the problem that arraylist needs to be boxed for value types.

-------------------------------------

An array is a value object, which stores a series of positions of values of the data element type.

Arraylist and list provide data for adding, deleting, and other operations.

Element Types in generics are fixed.

Arraylist can be used to add any type of elements.
