parse number range

[gem46]

how to find numbers entered in textbox that have a dash showing a range of numbers. UI enters numbers that can be anything. ie 1,2,5-10,55....etc.
need to find the numbers between 5 and 10 and convert all numbers entered into a string

Looks like an Adobe printing page range selection clone.

You'll have to write your own logic for that. There is no built-in control or .NET framework function for that.

I would probably use string.split to break the one string into an array at the commas.
Then check each array index for a hyphen
If there is one, parse the text before the hyphen as 'from, and after the hypen as 'to', then add each number in between (in a loop maybe)
