I hope some of these basic patterns have gotten you more interested in pursuing regular expressions. ;) Conclusion and Future Tutorials This tutorial was meant to be a (comprehensive) tutorial of the most basic regular expression syntax. There are still many more advanced concepts, but that will...
The regular-expression quantifiers (*, +, ?, {}) are greedy, meaning they match the longest possible string. However, for some patterns, you may want to use lazy matching to get the shortest possible string. The lazy regular-expression quantifiers are *?, +?, ??, and {}?. For more...
So now you have Visual Studio showing error squiggles under invalid regex patterns. Can you do more? If you’ve got the regular expressions domain knowledge to see not just what’s wrong with a pattern string but also how to fix it, you can suggest a...
