            intValAttr = new IntegerValidatorAttribute();

            long badValue = 10;
            int goodValue = 10;

            try
            {
                valBase = intValAttr.ValidatorInstance;
                valBase.Validate(goodValue);
                // valBase.Validate(badValue);
            }
            catch (ArgumentException e)

#endif
            }

        Dim valBase As ConfigurationValidatorBase
        Dim intValAttr As IntegerValidatorAttribute
        intValAttr = New IntegerValidatorAttribute()

        Dim badValue As Long = 10
        Dim goodValue As Integer = 10

        Try
            valBase = intValAttr.ValidatorInstance
            valBase.Validate(goodValue)
            ' valBase.Validate(badValue);
        Catch e As ArgumentException
