Can anyone please suggest the C# equivalent of Hex.decodeHex() which is in Java.

Below the example in java:

Key = "7777777777777777777777777777777777777777777777777777777777777777";
byte[] KeyInBytes = Hex.decodeHex(Key.toCharArray());

I am looking for the c# equivalent of this

Any help here is highly appreciated.

  • @TheGeneral decodeHex() Converts an array of characters representing hexadecimal values into an array of bytes of those same values. – Sammy Oct 14 '21 at 09:50

In .NET 5 and later you can use Convert.FromHexString().

Convert string to hex-string in C#, I think that you are trying to do something like this. I think it is Encoding.Default.GetBytes(Key); as the previous link shows

  • This is not correct. `Encoding.Default.GetBytes(Key)` does something completely different – canton7 Oct 14 '21 at 09:33
