I want to know if there is a better way (than what I'm currently doing) to obtain and hold a reference to a property in another object using only the object and property string names. Particularly, is there a better way to do this with the new dynamic functionality of .Net 4.0?

Here is what I have right now.

I have a "PropertyReference<T>" object that takes an object name and property name in the constructor.

An Initialize() method uses reflection to find the object and property and stores the property Getter as an Action<T> and the property Setter as an Func<T>.

When I want to actually call the property I do something like this:

int x = _propertyReference.Get();

or

_propertyReference.Set(2);

Here is my PropertyReference<T> code. Please dissect and make suggestions for improvement.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Reflection;
using System.Xml;

namespace WindowsFormsApplication2
{
    public class PropertyReference<T> : IPropertyReference
    {
        public string ComponentName { get; set; }
        public string PropertyName { get; set; }
        public bool IsInitialized
        {
            get
            {
                return (_action != null && _func != null);
            }
        }

        Action<T> _action;
        Func<T> _func;

        public PropertyReference() { }

        public PropertyReference(string componentName, string propertyName)
        {
            ComponentName = componentName;
            PropertyName = propertyName;
        }

        public void Initialize(IEntity e)
        {            
            Object component = e.GetByName(ComponentName);
            if (component == null) return;

            Type t = e.GetByName(ComponentName).GetType();
            PropertyInfo pi = t.GetProperty(PropertyName);

            _action = (T a) => pi.SetValue(component, a, null);
            _func = () => (T)pi.GetValue(component, null);
        }

        public void Reset()
        {
            _action = null;
            _func = null;

        }

        public void Set(T value)
        {
            _action.Invoke(value);
        }

        public T Get()
        {
            return _func();
        }

    }
}

Note: I can't use the "Emit" functionality as I need this code to work on the new Windows Phone 7 and that does not support Emit.
