Dynamic Linq Library Guid exceptions
- by Adan
I am having a problem with the Dynamic Linq Library. I get a the following error "ParserException was unhandled by user code ')" or ','". I have a Dicitionary and I want to create a query based on this dictionary. So I loop through my dictionary and append to a string builder "PersonId = (GUID FROM DICTIONARY). I think the problem is were I append to PersonId for some reason I can't seem to convert my string guid to a Guid so the dynamic library don't crash.
I have tried this to convert my string guid to a guid, but no luck.
query.Append("(PersonId = Guid(" + person.Key + ")");
query.Append("(PersonId = " + person.Key + ")");
I am using VS 2010 RTM and RIA Services as well as the Entity Framework 4.
//This is the loop I use
foreach (KeyValuePair<Guid, PersonDetails> person in personsDetails)
{
if ((person.Value as PersonDetails).IsExchangeChecked)
{
query.Append("(PersonId = Guid.Parse(" + person.Key + ")");
}
}
//Domain service call
var query = this.ObjectContext.Persons.Where(DynamicExpression.ParseLambda<Person, bool>(persons));
Please help, and if you know of a better way of doing this I am open to suggestions.
