Dynamically referencing properties in NHibernate?

I am now cutting my teeth on nHibernate and asked a question regarding dynamic access to properties in my persistent objects.

I have the following class in mine Domain:

public class Locations {
    public virtual string CountryCode;
    public virtual string CountryName;
}

Now, if I have a reference to the Locations object, is there a way for me to do something like this?

Locations myCountry = new LocationsRepository().GetByCountryCode("US");
myCountry.Set("CountryName", "U.S.A.");

instead of doing:

myCountry.CountryName = "U.S.A."

Without reflection?

I hate answering my questions on StackOverflow and I appreciate all the answers, but none of them did it for me. After some research, I found that the latest versions of NHibernate offer dynamic models .

public class Locations {

    public void Set(string propertyName, string value) {
        if (propertyName == "CountryCode") this.CountryCode = value;
        else if (propertyName == "CountryName") this.CountryName = value;
        else throw new ArgumentException("Unrecognized property '" + propertyName + "'");
    }
}

public class Locations 
{
  private Dictionary<string, object> _values;
  public Locations() 
  {
    _values = new Dictionary<string, object>();
  }
  public void Set(string propertyName, object value)
  {
     if(!_values.ContainsKey(propertyName))
        _values.Add(propertyName, value);
     else
        _values[propertyName] = value;
  }
  public object Get(string propertyName)
  {
     return _values.ContainsKey(propertyName) ? _values[propertyName] : null;
  }

  public string CountryCode
  {
     get{ return Get("CountryCode"); }
     set{ Set("CountryCode", value); }
  }
}

Thus, you can access the property without reflection and change it in one method. I have not tested this code, but I hope that this is what you mean by "do not have direct access to the property."
