c# - Match a regex and reverse the matches within the target string -



c# - Match a regex and reverse the matches within the target string -

based on this question regex \d+(?:-\d+)+ match 10-3-1 , 5-0.

example:

this 10-3-1 string

after performing matching , reversing, want this:

this 1-3-10 string

notice 10-3-1 should become 1-3-10 , not normal string reverse result in 1-3-01.

a basic algorithm be:

extract match string. "10-3-1" split match segments "-" character. you have list of elements. ["10","3","1"] reverse list. ["1","3","10"] join elements of array "-" character. "1-3-10" replace match newly joined string.
