How to make a separate space?

Example: I want make ASCII to Hex

Hello – 48656C6C6F

Answer 1

Or on one line

Dim hex = String.Join(" ", "Hello" _
    .Select(Function(c) Convert.ToByte(c).ToString("x2")))

without the Replace.

If you want to show the high bytes (because each Char is actually two Bytes because strings are Unicode)

Dim hex = String.Join(" ", "Hello" _
    .SelectMany(Function(c) BitConvertor.GetBytes(c)) _
    .Select(Function(b) b.ToString("x2")))
