How can I pass a property as a delegate?

Question

This is a theoretical question, I\'ve already got a solution to my problem that took me down a different path, but I think the question is still potentially interesting.

Worth mentioning you can do this with some reflection trickery.. something like...

public static void LoadFromReader(this object source, SqlDataReader reader, string propertyName, string fieldName)
    {
        //Should check for nulls..
        Type t = source.GetType();
        PropertyInfo pi = t.GetProperty(propertyName, System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance);
        object val = reader[fieldName];
        if (val == DBNull.Value)
        {
            val = default(T);
        }
        //Try to change to same type as property...
        val = Convert.ChangeType(val, pi.PropertyType);
        pi.SetValue(source, val, null);
    }

then

myClass.LoadFromReader(reader,"Property1","field1");
