Adding a URL Value to a String in VB.Net - vb.net

Question

I am having issues.
The script runs and builds the String and can Parse the Results, It receives a Accept Automatically then it searches for a value for RedirectURL.
How do i add a URL value to be build in the build version of my script.
Friend Overrides Function Filter() As String
Dim sb As New StringBuilder()
Return sb.ToString() '' Returning an empty string allows the applicant to be passed to the lender; otherwise the applicant is not sent
If app.BankAccount = String.Empty Then
sb.Append("Bank Account must be present;")
End If
If app.BankSortCode = String.Empty Then
sb.Append("Sort Code must be present;")
End If
If app.LoanAmount = String.Empty Then
sb.Append("Loan Amount must be present;")
End If
End Function
Friend Overrides Function Build() As String
Dim sb As New StringBuilder()
sb.AppendLine("&first_name=" & app.FirstName)
sb.AppendLine("&surname=" & app.LastName)
sb.AppendLine("&dob=" & app.DOB.ToString)
sb.AppendLine("&email=" & app.Email)
sb.AppendLine("&home_phone=" & app.LandPhone)
sb.AppendLine("&mobile_phone=" & app.MobilePhone)
sb.AppendLine("&postcode=" & app.PostCode)
sb.AppendLine("&affid=" & app.affID)
sb.AppendLine("&subid=" & lendertier.Credential1)
sb.AppendLine("&leadid=" & lendertier.Credential2)
sb.AppendLine("&bk_no=" & app.BankAccount)
sb.AppendLine("&bk_s=" & app.BankSortCode)
sb.AppendLine("&ar=" & app.LoanAmount.ToString)
Return sb.ToString()
End Function
Friend Overrides Function ParseResult(ByVal sResult As String) As Boolean
app.Outcome.RedirectURL = sResult
AcceptLead()
Return True
End Function

This question isn't overly clear but I'll give it a shot...
I think you are after retrieving the application version number and including it in the paramaterse in which case you will need something like:-
Dim versionNumber As Version
versionNumber = Assembly.GetExecutingAssembly().GetName().Version
You will have to import System.Reflection for this to work.
