C# Combine Regex Expressions

Question

I would like to combine a few expressions to get 3 different results per line.

Example: element\data\elements.data|44a0b61d1952973f52ad54cb911c0e3e|33095223

.*?element(?:(?!\|).)* retrieves element\data\elements.data

(?<=\|)(.*?)(?=\|) retrieves 44a0b61d1952973f52ad54cb911c0e3e

(?<=\|)[0-9]*\r retrieves 33095223

But for me to get these I currently am doing 3 different RegEx, and I would like to limit it down to only one to get the 3 results I need and set them to different variables.

I have looked into doing a Dictionary but those only allow 2 variables, while I need 3.

The expressions a, b and c match a, b and c respectively. How do you match abc? — Jon

I'm confused on your objection to using a Dictionary. You can have Dictionary<string,Collection<type>()>, and if all of your parameters for retrieval are unique that would make a great key. — Felix Castor

You could just split on the vertical pipe:

var elements = string.Split('|');

The resulting string array would contain:

element\data\elements.data
44a0b61d1952973f52ad54cb911c0e3e
33095223

+1 This worked perfectly, is there a way to set each string array to a variable? like var file = "element\data\elements.data", var hash = 44a0b61d1952973f52ad54cb911c0e3e, and var bytes = 33095223

For having a Regex with multiple matches you should take a look add | between your expressions. This will then return you all the results matching any of the pattern, with no distinction which string was found by which match.
