Get PropertyInfo of a parameter passed as lambda expression

Question

For example, I have a class:

public class Person
{
  public int Id;
  public string Name, Address;
}

and I want to call a method to update

Answer 1

This is possible, and there's no need to use PropertyInfo.

You'd design your method like so:

public bool Update(int id, Action updateMethod)
    // where T  : SomeDbEntityType
{
    T entity = LoadFromDatabase(id); // Load your "person" or whatever

    if (entity == null) 
        return false; // If you want to support fails this way, etc...

    // Calls the method on the person
    updateMethod(entity);

    SaveEntity(entity); // Do whatever you need to persist the values

    return true;
}
