find number in a string

[androoo]

Hello all,

I have a string for example :

strTest = "a lineof text (60) witha number in it"

I need to extract the number from between the brackets, the postion of
the number in brackets is never the same...

So in the above example i need to extract 60

Anyone help on how to do this the simplest way ?

Thanks

I would use regular expressions - you can specific the search pattern to
only search for numeric characters... like:

[0-9](1,) which will search for 1 or more numeric characters.

This can work but it is incredibly weak:

Dim strTest As String = "a lineof text (60) witha number in it"

Dim Results As String() = strTest.Split(N ew Char() {"("c,
")"c}, 3)

If Results.Length = 3 Then
Console.Write(" I found " & Results(1) & vbCrLf)
End If

Hey Androo,

Try this code:

'
' Create a regex object
'
dim myRegex as new
System.Text.Reg ularExpressions .Regex("(?<numb er>\d+)")
'
' Collect our input string
'
dim myInputString as string = "a lineof text (60) witha number in it"
'
' Capture our input
'
dim myNumber as string =
myRegex.Match(m yInputString).G roups("number") .Value
'
' Use it as we will
'
Console.WriteLi ne(myNumber)

Androoo,

You should use Rad's solution.
