C # Regular Expressions: matching strings specifying character contents

1 Functional Requirements
Match string "M1.large (vcpu 2,ram 4G) |c95f5529-47e8-46d4-85da-319eb9905a9b". Target string vcpu: "2", Ram: "4", ID: "c95f5529-47e8-46d4-85da-319eb9905a9b".

3 Regular Expression Specification reference

+: Matches the preceding subexpression one or more times. For example, "zo+" can Match "Zo" and "Zoo", but cannot match "Z". + is equivalent to {1,}.

X|y: Matches x or Y. For example, "Z|food" can match "Z" or "food". "(z|f) Ood" matches "Zood" or "food". [^XYZ]: Negative character set combination. Matches any characters that are not included. For example, "[^ABC]" can match "P" in "plain".

(? =pattern): Positive and positive check. For example, the Windows (? =95|98| nt|2000) "Can match" Windows "in" Windows2000 ".

(? <=pattern): Reverse positive check. For example, "(? <=95|98| nt|2000) Windows "can match Windows" in "2000Windows".
