How to use MarketingExpressionEvaluator.Evaluate ?

Hi,



I needed a way to use commerce server objects to evaluate expressions. I
want use ExpressionEvaluator object to evaluate target expressions and
catalog expressions, but couldn't find the way to evaluate this expressions.
I want the evaulation's result to be assigned to
ExpressionEvaluator.ExpressionResult object. But I don't set to
TarrgetingProfileCollection of the ExpressionResults' parameters. For this
reason ExpressionResult returns the "UndefinedResult" value, but the
expected values are "true" or "false".



Below i have upplied the code that i expect to return boolean value, but it
returns "UndefinedResult"



UserObjectProfile profile = CurrentUser.GetUserProfile(true);

Microsoft.CommerceServer.Runtime.Profiles.Profile userprofile =

CommerceContext.Current.ProfileSystem.GetProfile(" {" + profile.Id.ToString()
+ "}", "UserObject");

TargetingProfileCollection profiles = new TargetingProfileCollection();

profiles.Add("Profile",userprofile);



MarketingExpressionEvaluator expressionEvaluator = new
MarketingExpressionEvaluator(connectionString,
CommerceContext.Current.DebugContext);

MarketingExpressionEvaluator.ExpressionResult result =
expressionEvaluator.Evaluate(expressinid, profiles);
