Question

How can i get the string within a parenthesis with a custom function?

e.x. the string “GREECE (+30)” should return “+30” only

Answer 1

There are some different ways.

Plain string methods:

Dim left As Integer = str.IndexOf('(')
Dim right As Integer= str.IndexOf(')')
Dim content As String = str.Substring(left + 1, right - left - 1)

Regular expression:

Dim content As String = Regex.Match(str, "\((.+?)\)").Groups[1].Value
