    How do I use if statement to check number in string array?

    My shared sub, the strCitationNumbers string array can have a number or 'No match' text.

    I would like to add if statement to check strCitationNumbers has a number in it.
    If a number (string) is found in the strCitationNumbers, I want to output an error message saying 'Duplicate case found'.
    How do I do it?
    Shared Sub TestCitationGetCaseNumber()
             Dim strCitationNumbers() As String
            Dim strCitationNumber As String = "2770043451123"
     strCitationNumbers = Msc.Integration.Mncis.Library.v4.Citation.GetCaseNumbersForCitation(strCitationNumber, False)   End Sub

    If it's either "No match" or a number, can't you just test whether the value is/isn't "No match"?

    you need to traverse the citation numbers from the first to the penultimate with a loop "a" and within that loop you need a second loop "b" that traverses the citation numbers from the second one to the last
    when the citation numbers match you can report the citation number back as a duplicate. this will report all duplicates, if the report contains duplicate numbers then the citation number has been use more than twice.

    straight forward to code
