JSON mit Punkt im Namen

  /// <summary> Parses a JSON path with names and indexes.</summary>
  /// <remarks>
  ///  The syntax to write paths is similar to XPath but in a Json way.
  ///  The following XPath expression:
  ///    /entities/urls[0]/indices[1]
  ///  would look like
  ///    entities.urls[0].indices[1]   (dot notation)
  ///  or
  ///    entities["urls"][0]["indices"][1]   (bracket notation)
  ///
  ///  The dot (.) token is used to access the object elements:
  ///    ex: object.key
  ///
  ///  The bracket ([]) token is used to access array or object elements:
  ///    In array: cities[0]
  ///    In object: city["name"] or city['name']
  ///    In object: ["city"]["name"] or ['city']['name']
  ///
  ///  The quote (" or ') is used to introduce a literal when the element is being written in bracket notation:
  ///    ex:["first"]["second"] or ['first']['second']
  ///
  ///  To escape the quote in a literal use backslash (\): \"
  ///    ex: ["quotes(\").should.be.escaped"] or ['quotes(\').should.be.escaped']
  ///
  ///  Note: The backslash will only escape quotes within a literal. Bracket notation can be useful when
  ///  names can not be written in dot notation, like the objects keys with dot characters:
  ///    ex: object["key.with.dots"] or object['key.with.dots']
  ///
  /// </remarks>

Zitat:

Note: The backslash will only escape quotes within a literal. Bracket notation can be useful when
names can not be written in dot notation, like the objects keys with dot characters:
ex: object["key.with.dots"] or object['key.with.dots']
