vb.net - Regex.Replace unable to make it work -


i expect following code replace every occurence of whitespace+digit+whitespace replacing anything+digit+anything.

nswapfirstpart = regex.replace(nswapfirstpart, "\w[0-9]\w", " _ ")

thanks

you using \w refers non-word character , denoted by

[^a-za-z0-9_]

so match special characters, spaces, not alphabet, digit or underscore.

you need use \s denotes whitespace characters , denoted by

[ \t\r\n\v\f]

as such, use:

"\s[0-9]\s"

instead of

"\w[0-9]\w"
