Dynamic byte array

[mce]

I need to use a dynamic byte array. How to declare a dynamic byte array in csharp?

for example:

//This is fixed size.
byte[] l_byteArray = new byte[100];

How can i declare a dynamic byte array where i can add any number of bytes to an existing byte array?

do you have a delimiter or do you just want to add bytes one by one to the array

You could always use:

List<byte> list = new List<byte>();

This gives you type safety and the ability to insert, remove, etc.

Although maybe you're looking for something a little slicker, but unfortunately I don't think an array is what you want to use since you're constrained by the size you define it by at run-time.

Edit: Oh, and you can always convert it back to a byte[] by calling list.ToArray()

Thanks!

another question;

Instead of copying byte by byte myself, is there a function (more efficient) to append a byte array to a stack of byte, where the last byte in the byte array i want to copy, such as byteArr[99] is appended to the bottom of the stack.

byte [] byteArr = new byte[100];
byte [] byteArr2 = new byte[100];
Stack<byte> stackByteStream = new Stack<byte>();

I want to copy byteArr and byteArr2 to stackByteStream to process the buffer.

When you speak of Stacks, using a term such as append really shouldn't apply. Stacks are a very specific data structure and should really only be modified via the Push, Pop, or Clear calls.

I'd say stick with the List<byte> and just do AddRange calls so you can avoid iterating every time you need to insert (or append) a List<byte> into it.
