Question

My program outputs strings like "Wzyryrff}av{v5~fvzu: Bb``igbuz~+\177Ql\027}C5]{H5LqL{" and the problem is the escape codes (\\\ instead of \, \177 instead of the character, etc.)

I need a way to unescape the string of all escape codes (mainly just the \\\ and octal \027 types). Is there something that already does this?

Thanks

The strings are an encrypted value and I need to decrypt them, but I’m getting the wrong values since the strings are escaped

There is nothing built in to do exactly this kind of escaping.

You will need to parse and replace these sequences yourself.

The \xxx octal escapes can be found with a RegEx (\\\d{3}), iterating over the matches will allow you to parse out the octal part and get the replacement character for it (then a simple replace will do).

The others appear to be simple to replace with string.Replace.
