How to declare a byte ArrayList

Question

I am trying to do

var mahByteArray = new ArrayList<byte>();

And it does not work. It says this:

The non-generic type 'System.Collectios.ArrayList' cannot be used with type arguments

What is the proper way to do declare a byte ArrayList?

Answer 1

You are confusing Java ArrayList collections with C# List generic collections. Both are used to declare collections, but the first one is used in Java as being a type defined in the generic class List for Collections framework and in the last one is used in C# language as an implicit generic type.

So, you must declare as being a List type. See details on List.

var mahByteArray = new List<byte>();

or

List<byte> mahByteArray = new List<byte>() { 2, 3, 4 };

Answer 2

sure you can use a ArrayList

var mahByteArray = new ArrayList();
mahByteArray.Add((byte) 230);
