Lost escape sequences

When i deserialize a string type property which contents "rn" data,  i’ve lost a ‘n'(‘new line’). As a result was text data’s bad formatting.
This problem was solved by replacing with the regular expression "(?<!\r)\n".

public string Note




//HACK: При сериализации символ rn заменяется на n

//восстанавливаем первоначальные значения

_note =

Regex.Replace(_note, "(?<!\r)\n", "rn");

return _note;


set { _note = value; }
