Question

I have this string I have retrieved from a File.ReadAllText:

6   11 rows processed

As you can see there is always an integer specifying the line number in this document. What I am interested in is the integer that comes after it and the words “rows processed”. So in this case I am only interested in the substring “11 rows processed”.

So, knowing that each line will start with an integer and then some white space, I need to be able to isolate the integer that follows it and the words “rows processed” and return that to a string by itself.

I have been told this is easy to do with Regex, but so far I haven’t the faintest clue how to build it.

Answer 1

This should work for what you need:

\d+(.*)

This searches for 1 or more digits (\d+) and then it puts everything afterwards in a group:

. = any character
* = repeater (zero or more of the preceding value (which is any character in the above
() = grouping

However, Jason is correct in that you only need to use a split function
