This is the code for my array (which is working)

Public numUsers As Integer
Public fNameUsers As String = ("..\..\..\users.txt")
Public UserRecords As Usersclass() 'note... this line is in a module '

reader = New System.IO.StreamReader(fNameUsers)
numUsers = 0

   'Split the array up at each delimiter of "," and add new objects '
            Do While reader.Peek <> -1
                ReDim Preserve UserRecords(numUsers)
                oneline = reader.ReadLine
                fields = oneline.Split(",")
                UserRecords(numUsers) = New Usersclass
                UserRecords(numUsers).AccountNumber = fields(0)
                UserRecords(numUsers).CourseName = fields(1)
                UserRecords(numUsers).FirstName = fields(2)
                UserRecords(numUsers).LastName = fields(3)
                UserRecords(numUsers).DOB = fields(4)
                UserRecords(numUsers).Email = fields(5)
                UserRecords(numUsers).CourseProgress = (6)
                UserRecords(numUsers).AdminCheck = fields(7)

                numUsers = numUsers + 1

            Loop
            reader.Close()

My problem is that I don't know how to lookup the index of an array where the .accountNumber = a variable. For example the acccountNumber is 253, what is the code to find the index this relates to????

Thanks in advance
