Hey!

Try this…

Create a Boolean variable…

Assign boolVar = System.Text.RegularExpressions.regex.IsMatch(YourString,"[0-9]")

This will give you the Boolean value…

You can use this is in if condition…

boolVar=true

In then block you can do whatever you want…

OR

You can use

isNumeric(string variable)

Hello @saritha

Are you checking whether the string starting with a numeric or alphabet or the entire string is numeric or not? pLease clarfy.

If you want to check the string starts with Numeric, you can use startsWith Method. : Isnumeric(InputVariable.substring(0))
InputVariable is the varibale holding the value.

If entire string to be checked, then do as : _booleanResult = isNumeric(_input)

No, I’m looking for string starts with numeric or not

You can use the below expression. It will give you a boolean result. Then you can use an if condition.
