How to Convert string to byte[] without conversion in C#

Question

I want to convert string to byte[] without conversion/changing value. Example:
string value "10,34,56,64,32" after converting to byte[] also should be { 10, 34, 56, 64, 32 }.

This one is giving me unexpected result:

var result = Encoding.ASCII.GetBytes("10,34,56,64,32");

Question is fairly straightforward. One suggestion might be to show what the "unexpected result" is — Geoff James, May 09 '17 at 11:42

@GeoffJames Question is absolutely straight forward. It's just not researched *nearly* enough. The output wouldn't be unexpected if OP had read the documentation for the method. But anyway. An answer has been provided. — J. Steen, May 09 '17 at 11:46
@J.Steen absolutely agree. lol'ing all the way at your comment... — Geoff James, May 09 '17 at 11:48

How about

byte[] result = "10,34,56,64,32".Split(',').Select(byte.Parse).ToArray();

If needed also .Trim(new char[]{'{','}'}) – Daniel Frühauf May 09 '17 at 11:46

@DanielFrühauf God no. `Split` doesn't include the character it splits on, and even if it did you could just `Trim(',')` – Tamás Szabó May 09 '17 at 11:47
He had "{" and "}" in his string before in the question. – Daniel Frühauf May 09 '17 at 11:48
@DanielFrühauf Likely an artefact from OP reading the debugger visualiser output, rather than what's actually in the variable. – J. Steen May 09 '17 at 11:49
@DanielFrühauf Ah, sorry, I see what you mean. I think that was just debugger output, as J. Steen said. – Tamás Szabó May 09 '17 at 11:51
@TamásSzabó Yeah. In the code example there are no brackets. – Daniel Frühauf May 09 '17 at 11:52
