Best practice for dynamic LINQ updates

Hi,

In my REST Controller I have a HTTP/PUT handler method. The issue is that when I receive updates, I do not want to send everything over the wire if only one property has changed.

The way I do it now is having the handler accept a dynamic parameter, which I then apply to my LINQ objects by reflection.

It works, but it makes me feel dirty. There must be a better method?

Example Code (abbreviated):

public void Put(dynamic value)
{
    var db = new MyContext();
    int id = (int)value.ID;
    Employee e = db.Employee.SingleOrDefault(r => r.ID == id);
    foreach (JProperty prop in value)
    {
        if (prop.Name != "ID" && prop.Name != "")
        {
            PropertyInfo pi = e.GetType().GetProperty(prop.Name);
            if (pi.CanWrite)
            {
                JToken jt = (JToken)prop.Value;
                var val = Convert.ChangeType(jt, pi.PropertyType);
                pi.SetValue(e, val, null);                            
            }
        }
    }
    db.SaveChanges();
}
