c# - Match string like ?$skip=[0-9] -

i want match odata string ^\$skip=[0-9]$ match things $skip=3 , remove them. regex wrong don't know try next. i've tried various things wrapping in [] , on.

here online example: http://www.regexr.com/392m2

you using ^\$skip=[0-9]$. regex match line has pattern. line must start , finish $skip=n so, that's why test didn't work.

if have $skip=3 separated words can use:

\b\$skip=\d+\b 

above match if have: blabla blab bla $skip=3 bla

if want remove it's appearing can use \$skip=\d+

\$skip=\d+
