UKModulusCheck

Usage from C#

Prerequisites

To use the library from C# you'll need to add reference to FSharp.Core package to your project. You can grab it from NuGet.

Usage

To check the sort code / account number pair you'll need:

You can obtain newest version of both files from VocaLink.

Once you got the files, you need to create an instance of Validator class and initialize it by loading the data into memory using the LoadData method:

 1: 
 2: 
 3: 
 4: 
 5: 
 6: 
 7: 
 8: 
 9: 
10: 
11: 

using UkModulusCheck.CSharp;

var validator = new Validator();
try
{
    validator.LoadData("valacdos.txt", "scsubtab.txt");
}
catch (Exception ex)
{
    Console.WriteLine($"Error loading data from files: {ex}");
}

You can find the details of the method in the reference docs.

To validate the sort code and account number pair use the ValidateAccount method:

1: 
2: 
3: 
4: 
5: 
6: 
7: 
8: 
9: 

var sortCode = "000000";
var accountNumber = "12345678";

var result = validator.ValidateAccount(sortCode, accountNumber);

if (result.IsValid)
    Console.WriteLine($"{sortCode}-{accountNumber} is valid :)");
else
    Console.WriteLine($"{sortCode}-{accountNumber} is Invalid :( Reason: {result.FailureReason}");

For more information about the API and types used by the library please check the reference docs.

Notes

Loading the data using the LoadData method modifies the state of the Validator class instance and should be considered thread unsafe. Validating the data using the ValidateAccount method doesn't modify the state and can be considered thread safe.
