推荐答案

首先学习正则表达式。这就像用叉子和刀子吃饭：如果你不设法处理它们，你就会削减自己。与任何其他尖锐工具（如正则表达式等）相同。

PS：急引发了很多人的反应，只是为了不回答最好的问题，然后对问题进行投票，以便尽快删除。

所以，我敦促你严格避免紧急这里发布的任何问题。

Learn Regex first. It's like eating with fork and knife: If you don't manage to handle them, you cut yourself. The same with any other "sharp" tool (like Regex, etc.).

For getting started quickly or for more elaborate tutorials, see:
- The 30 Minute Regex Tutorial[^]
- http://www.tutorialspoint.com/vb.net/vb.net_regular_expressions.htm[^]
- https://www.google.com/search?q=regex+tutorial+VB[^]

Is this quick enough for your "urgent" request? ;-)

Cheers
Andi

PS: "urgent" triggers a reflex with many people for just not answering at best, and down-voting the question so it gets deleted soon, at worst.
So, I "urge" you to strictly avoid "urgent" in any of the questions posted here.
