ReadMember() публичный Метод

Reads a member with a given (case-sensitive) name and returns a JsonReader that can be used to read the value. Otherwise it throws an exception.
The caller should not use the returned JsonReader instance for any other purpose but reading the value. It is possible that this method will return the same instance as BaseReader or a separate instance.
