Translate string literals to their actual values [duplicate]

Answer 1

This is actually quite complex, there are many more cases than you describe that need to be accounted for in order to parse string literals. Consider for example \0x0a. Fortunately, you are not the first person requesting this. Regex.Unescape handles most, but not all cases. DeepDiver has a blog post with code that parses C# literal strings - this should do what you request.

Answer 2

You could try to use the System.Text.RegularExpressions.Regex.Unescape static method:

string internal_ = Regex.Unescape(printable);

But unfortunately it applicable mainly for Regex control characters.

Test:

var chars = internal_.ToCharArray();

The chars array has 1 element with code 0x0a.
