Regular Expression for numbers and combinations

[Paul_Andrei_Turcu]

Hello,

I need help in building a regex. My initial string message looks like this:

I need a bool regex that should be true if the 1st word is a number, or a combination of numbers devided by “-” character.

So if i run I expect to have the values of 1 and 1-2 as outputs from my example variable

So far I came up with this one that works but if my first word is “12word” then the output will be 12word and i want it to be just 12.

Thank you!

HI @Paul_Andrei_Turcu

Check with this

For Boolean
(Single digit)
System.Text.RegularExpressions.Regex.IsMatch(stringVar,“^\d+")

(Digits divided by “-”)
System.Text.RegularExpressions.Regex.IsMatch(stringVar,“\d±\d+")

For getting values
(Single digit)
System.Text.RegularExpressions.Regex.Match(stringVar,“^\d+").Tostring

(Digits divided by “-”)
System.Text.RegularExpressions.Regex.Match(stringVar,“\d±\d+").ToString

Hi @Paul_Andrei_Turcu

You can try with this expression to get 12

YourString = “1 word 1 word2”

System.Text.RegularExpressions.Regex.Replace(YourString,"word|^\d|\s","").Tostring.Trim

Thank you but seems that i cant understand.

“word” word is just an example not an anchor based word in my example

If my string input is like
“1 have a nice day” => “1”
“1-2 have a nice day” => “1-2”
“1have a nice day” => “1”
“1-2have a nice day” =>“1-2”

The ideea is to treat the chase of not having a space and as a general rule, my number or combo of numbers are allways at the start of my string var.
