• Took each bit of code from an answer here:
• BitConvertRep = Answer by Guffa, BitConverter and String.Replace (I'd recommend for most cases)
• StringBuilder = Answer by Quintin Robinson, foreach char StringBuilder.Append
• LinqConcat = Answer by Michael Buen, string.Concat of Linq built array
• LinqJoin = Answer by mloskot, string.Join of Linq built array
• LinqAgg = Answer by Matthew Whited, IEnumerable.Aggregate with StringBuilder
• ToHex = Answer by Kurt, sets chars in an array, using byte values to get hex
• ByteArrayToHexString = Answer by Nathan Moinvaziri, approx same speed as the ToHex above, and is probably easier to read (I'd recommend for speed)
• ToHexFromTable = Linked in answer by Nathan Moinvaziri, for me this is near the same speed as the above 2 but requires an array of 256 strings to always exist

.Net5.0 Update

Thanks to @antoninkriz's benchmark comparison we can see that Convert.ToHexString is by far the clear winner today

You'd be foolish to use anything other than Convert.ToHexString. In my opinion it clearly wins in: readability, performance, safety

The rest of this is from before Apr 10, 2012:

• BitConvertRep = Answer by Guffa, BitConverter and String.Replace (I'd recommend for most cases, [edit:] where you can't use Convert.ToHexString)

I thought I would attempt to compare the speed of each of the methods listed here for the hell of it. I based the speed testing code off this.

The result is that BitConverter+String.Replace seems to be faster than most other simple ways. But the speed can be improved with algorithms like Nathan Moinvaziri's ByteArrayToHexString or Kurt's ToHex.

Also another answer with a similar process, I haven't compared our results yet.
