how to create expression tree / lambda for a deep property from a string

Question

Given a string: \"Person.Address.Postcode\" I want to be able to get/set this postcode property on an instance of Person. How can I do this? My idea was to split the string

Answer 1

Why you don't use recursion? Something like:

setProperyValue(obj, propertyName, value)
{
  head, tail = propertyName.SplitByDotToHeadAndTail(); // Person.Address.Postcode => {head=Person, tail=Address.Postcode}
  if(tail.Length == 0)
    setPropertyValueUsingReflection(obj, head, value);
  else
    setPropertyValue(getPropertyValueUsingReflection(obj, head), tail, value); // recursion
}
