Hi there,

Hoping this is a nice softball of a question for a friday but I have the following line of code:

//System.ArgumentOutOfRangeException generated if there is no matching data
            currentAnswers = new CurrentAnswersCollection().Where("PARTICIPANT_ID", 10000).Load()[0];

CurrentAnswersCollection is a strongly-typed collection populated by a view going back to my database. The problem of course is that if there is not a corresponding PARTICIPANT_ID = 10000 I get the error message.

Is there a better way to write this so that I wouldn't get the error message at all? I just dont know enough about LINQ syntax to know if I can test for the existance first?
