Check if a string contains only characters from a predefined list

[Kapil (Kapil Parmar)]

Hi,

I am having list of characters !@#$%^&* ()_

I want to check if my test string contain characters only from above string. Exa,
Test string 1: “*&vgjgu^%$”
Output: False as it contains characters which are not in predefined list.

Test string 2: “&%^#%)(”
Output: True as it contains characters only from the predefined list.

Can anyone please help with logic for above without using iteration.

Thanks

Hello

Try this:
yourStr = your text.

Insert the following into an IF Activity:
System.Text.RegularExpressions.Regex.IsMatch(yourStr,“[^\!|\@|\#|\$|\%|\^|\&|\*|\s|\(|\)|_]”) = False

Hey @Kapil

Where character is the list of characters just apply this:

testString1.All(Function(c) character.Contains(c)

)
Put this inside the if condition where testString1 is the test String you mentioned
