Replace (regex) problems

studio

#1

I’m having problems with the Replace function for a string, with regex.
I’m trying to escape all characters except numbers and text.

The second Replace function is working properly (I need to escape everything except text). I can’t seem to find the problem, or difference between the two functions.

Function1:
Knipsel

–> the output stays the same as the input (even if I change the output variable to a new)

Function2:

Knipsel2

–> the output is as expected

Hi,

I have this saved to remove Specials only (keeping numbers and text)
"[^\w\d]+"

So you could try that one.

The one-liner would look like this:
System.Text.RegularExpressions.Regex.Replace(text, “[^\w\d]+”, “”)

Thanks.

Thank you for putting me on the right track.
Your solution still let the underscores pass.
I used this eventually: [^a-zA-Z0-9]

Good thinking using [^a-zA-Z0-9]
I didn’t know it would leave underscores; I will remember that next time. Thanks.
