Question

I am following the http://wiki.fluentnhibernate.org/Getting_started tutorial to create my first NHibernate project with Fluent NHibernate

I have 2 tables

A Great way to do this, is implement the interface IUserType and Create a CustomType with the rules to write and read, that´s a example to boolean:

 public class CharToBoolean : IUserType
{
    public SqlType[] SqlTypes => new[] { NHibernateUtil.String.SqlType };

    public Type ReturnedType => typeof(bool);

    public bool IsMutable =>true;

    public object Assemble(object cached, object owner)
    {
        return (cached);
    }

    public object DeepCopy(object value)
    {
        return (value);
    }

    public object Disassemble(object value)
    {
        return (value);
    }

    public new bool Equals(object x, object y)
    {
        if (ReferenceEquals(x, y)) return true;

        var firstObject = x as string;
        var secondObject = y as string;

        if (string.IsNullOrEmpty(firstObject) || string.IsNullOrEmpty(secondObject)) return false;

        if (firstObject == secondObject) return true;
        return false;
    }

    public int GetHashCode(object x)
    {
        return ((x != null) ? x.GetHashCode() : 0);
    }

    public object NullSafeGet(IDataReader rs, string[] names, object owner)
    {
        var obj = NHibernateUtil.String.NullSafeGet(rs, names[0]);

        if (obj == null) return null;

        var value = (string)obj;

        return value.ToBoolean();
    }

    public void NullSafeSet(IDbCommand cmd, object value, int index)
    {
        if(value != null)
        {
            if ((bool)value)
            {
                ((IDataParameter)cmd.Parameters[index]).Value = "S";
            }
            else
            {
                ((IDataParameter)cmd.Parameters[index]).Value = "N";
            }
        }
        else
        {
            ((IDataParameter)cmd.Parameters[index]).Value = DBNull.Value;
        }
    }
    public object Replace(object original, object target, object owner)
    {
        return original;
    }
}

}

the mapping:

  this.Map(x => x.DominioGenerico).Column("fldominiogen").CustomType();

It´s a sample but you can do this with other types.
