    Macro Parameters strongly typed?

    Hi guys I'm passing a number through as my macro parameter I was just wondering if this was strongly typed and how to check for it on the other end i.e. would it be something like @Parameter.numberOfItemsToDisplay != -1?

    All @Parameter values are passed as a string - you will need to cast them to their correct type. To avoid run-time errors it's probably best practice to do something like this:


    int noOfItems;
    if (!int.TryParse(Parameter.numberOfItemsToDisplay, out noOfItems))
    {
      noOfItems = 0;
    }

     That way if the parameter can't be cast (say it is missing or not a number) you get a default value of zero for it.
