My question is how can I convert,
string s = "Hello World";
into
byte b = {0x48, 0x65, 0x6C, 0x6C, 0x6F, 0x20, 0x57, 0x6F, 0x72, 0x6C, 0x64};
If there is a straightforward way in C# .NET Core then it will be very helpful.

The phrase "byte array in hex" makes no sense; bytes are bytes - they don't have any intrinsic format such as decimal, hex, octal: they're just values.
However, what you want is probably:
byte[] bytes = Encoding.UTF8.GetBytes(s);
to get the hex, you can then use tools to get a string again, for example:
string hex = BitConverter.ToString(bytes);
If you say you want an array of bytes for a given string, you have to specify in which way the byte array should represent the string. That's called encoding and the .NET framework has a built-in library (System.Text.Encoding) for handling string encoding operations.
For example, in order to get the string as ASCII representation, use this:
byte[] bytes = Encoding.ASCII.GetBytes(someString);
Of course, ASCII is a very limited set of characters.
Just explore your option here:
