Conversion between Base64String and Hexadecimal

Question

I use in my C++/CLI project ToBase64String to give a string like /MnwRx7kRZEQBxLZEkXndA== I want to convert this string to Hexadecimal representation, How I can do that in C++/CLI or C#?

Answer 1

FromBase64String will take the string to bytes

byte[] bytes = Convert.FromBase64String(string s);

Then, BitConverter.ToString() will convert a byte array to a hex string ( byte[] to hex string )

string hex = BitConverter.ToString(bytes);

Answer 2

Convert the string to a byte array and then do a byte to hex conversion

string stringToConvert = "/MnwRx7kRZEQBxLZEkXndA==";

byte[] convertedByte = Encoding.Unicode.GetBytes(stringToConvert);

string hex = BitConverter.ToString(convertedByte);

Console.WriteLine(hex);
