Parameters

| Name | Details|
| ------ | ------ |
| Pattern | The `string` pattern that has to be used for the lookup. For more information: [msdn][1]|
| RegexOptions *[Optional]* | The common options in here are `Singleline` and `Multiline`. They are changing the behaviour of pattern-elements like the dot (.) which won't cover a `NewLine` (\n) in `Multiline-Mode` but in `SingleLine-Mode`. Default behaviour: [msdn][2] |
| Timeout *[Optional]* | Where patterns are getting more complex the lookup can consume more time. This is the passed timeout for the lookup just as known from network-programming.|

Remarks

Needed using

using System.Text.RegularExpressions;

Nice to have

Especially beginners are tended to overkill their tasks with regex because it feels powerful and in the right place for complexer text-based lookups. This is the point where people try to parse xml-documents with regex without even asking theirselfes if there could be an already finished class for this task like XmlDocument.

Regex should be the last weapon to pick agains complexity. At least dont forget putting in some effort to search for the right way before writing down 20 lines of patterns.
