How to set the length of byte[]

[flyfish]

If some function just like

SetLength(byteData,100)

.....?

The array length is set when you instantiate the array, and can't be
changed after that.

ArrayLists on the other hand can grow and shrink in size. But I
generally wouldn't recommend using that a replacement for a byte[]
since every byte would be boxed.

You can't change the length, but you could allocate a new array of larger
size and copy current array into it.
byte[] SetLenght(byte[] currByteArray, int newSize)
{
if ( currByteArray.Length > newSize)
//error
byte[] newArray = new byte[newSize];
// copy currArray to newArray.
return newArray;
}

Other error checks are needed.

Hmmm.. is that going to be true with generics as well?

No, I don't believe so.
