Prepara texto para insertarlo de forma segura en una cadena C#.
Genera la forma escapada adecuada para cadenas C#, con opción de estilo verbatim (@"...").
Backslash becomes \\, quotes become \" and \', line break \n, carriage return \r, tab \t, null \0, form feed \f, vertical tab \v. In verbatim mode only " becomes "".
In a regular string the backslash starts an escape sequence. In a verbatim string, written @"...", it does not, which makes file paths and regexes far more readable. Only the double quote has to be doubled.
Yes, it can span several lines, and the line breaks become part of the string.
In $"..." strings, curly braces also have a special meaning and must be doubled. This tool does not double them.
If your project can use them, triple-quoted raw strings need no escaping at all, which is handy for JSON.
