Get number from string c#
Say I have a string such as "20 Boxes" and I want to extract the number from that string as an integer to carry out some calculations on it. How should I go about this? I'm used to using parseInt, but in Unity unlike in JS that won't accept any string that contains letters, so that's out unless I split the string up first. If I do have to split the string up first, what's the most efficient way to do so? You can use the String.SEE VIDEO BY TOPIC: How to Find Number from String in C# NET 2012

Okay thanks, I'll just use Split. Shame it can't take a string as a separator tho. Perhaps in version Cap : it can use string as a separator, however. Hmm, okay. I find it odd that it would require an array containing a string for a single separator, rather than just a string. Something to file away in the brain for later anyway.
You can also use Regex. I would also like to point out, before all the Webplayer-lovers hound me for it, that the RegularExpressions library adds about k to the web player download, so if this is unacceptable for you, don't use Regex. I looked into RegEx, but I thought it would contain some overhead since it has to load in that library, as opposed to using split and parse JS functions.
Do you know if there's any downside apart from that extra k game won't be made for the web? The library is included and loaded during startup, and it loads so fast you probably wouldn't even notice it. Okay, well I think I'll stick with Split for this but RegEx might be necessary later on in the project. If I can avoid using it then I suppose it would be nice to have k less even for the desktop.
But who's going to notice a few MB these days? Pretty much a non-issue like SpikeX said. Yea, and it'll get compressed for distribution on the desktop anyway, but i'll shave stuff off anywhere I can.
