Does C# have built-in support for parsing page-number strings?

Question

Does C# have built-in support for parsing strings of page numbers? By page numbers, I mean the format you might enter into a print dialog that\'s a mixture of comma and das

Answer 1

It doesn't have a built-in way to do this, but it would be trivial to do using String.Split.

Simply split on ',' then you have a series of strings that represent either page numbers or ranges. Iterate over that series and do a String.Split of '-'. If there isn't a result, it's a plain page number, so stick it in your list of pages. If there is a result, take the left and right of the '-' as the bounds and use a simple for loop to add each page number to your final list over that range.

Can't take but 5 minutes to do, then maybe another 10 to add in some sanity checks to throw errors when the user tries to input invalid data (like "1-2-3" or something.)
