check if it's a number 0 “zero”

Question

I'm using a regex code to check if the value of an output code, if it's, contains a number 0 (zero)

Btw, I'm using UiPath.

Here's what I did, but when it shows number 1, it sends me true, which it shouldn't!

Code :

System.Text.RegularExpressions.Regex.IsMatch("output_matches(0)","[0]")

Answer 1

what you are doing is passing a string with value "output_matches(0)" and not the actual content of the first element of the array. Since you have a 0 in that string it will match the regex.

If you simply need to check if output_matches(0) is the value "0" you can use the =-operator: output_matches(0) = "0".

If you need to check if output_matches(0) contains a zero you can use output_matches(0).contains("0")
