Online Hex till text Decoder

How do I convert a byte[] to a string? Every time I attempt it, I get

System.Byte[]

instead of the value.

Also, how do I get the value in Hex instead of a decimal?

I have a database table with fields such as with From and To as hex like:

From    To     dataA1234   A1239  HelloB2000   B4000  WorldC3000   C4000  Simple

I want to traverse and show the auto complete list of these such as:

• A1234 => Hello
• A1235 => Hello
• ....
• A1239 => Hello
• B2000 => World
• B2001 => World
• ....
• B4000 => World
• C3000 => Simple
• C3001 => Simple
• ....
• C4000 => Simple

At least I want to know how to make this as Dictionary<string,string> or some List. What could be the best strategy to do so?

(Note: I cannot change the database structure.)

I'm trying to find a way to print a string in hex. For example I have this string which I then convert to its hex value.

my_string = "deadbeef"my_hex = my_string.decode('hex')

How can I print my_hex as 0xde 0xad 0xbe 0xef? Thank you.

To make my question clear... Let's say I have some data like 0x01, 0x02, 0x03, 0x04 stored in a variable. Now I need to print it in hex so that I can read it. I guess I am looking for a python equivalent of printf("%02x", my_hex). I know there is print '{0:x}'.format() but that won't work with my_hex and it also won't pad with zeroes.

I hope this isn't too much of of a stupid questions, I have tired looking on 5 different pages of Google results but haven't been able to find anything on this.

What I need to do is convert a string that contains all Hex characters into ASCII for example

String fileName = 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

Every way I have seen makes it seems like you have to put it into an array first is there no way to loop through each two and convert them?

I have the following piece of code which converts 1 char to a hex at a time. I want to convert two chars to a hex. ie 99ab should be treated as '99', 'ab' to be converted to its equivalent hex.

Current implementation is as follows

$final =~ s/(.)/sprintf("0x%X ",ord($1))/eg;chop($final);
