Yes they are strings..
When i tried this

ValueExpression expression = (ValueExpression)Expression.Parse("Iron");

I am getting following error

System.InvalidCastException: Unable to cast object of type
'OSGeo.FDO.Expression.Identifier' to type
   at C3D_SDF.CRUD.update_data(String sdf_file, IConnection con, Editor ed)
in D:\SkyDrive\Dev Zone\Ms.NET\Projects\C3D_SDF\C3D_SDF\CRUD.cs:line 138

ValueExpression expression =
(ValueExpression)Expression.Parse('Iron');//this is not working either.
