How to use

To read NACHA file (using c# 7, otherwise use if-else statement)

foreach (var r in new ChoNACHAReader("20151027B0000327P018CHK.ACH"))
{
    switch (r)
    {
        case ChoNACHAFileHeaderRecord fileHeaderRecord:
            Console.WriteLine(fileHeaderRecord.ImmediateOrigin);
            break;
        case ChoNACHAFileControlRecord fileControlRecord:
            Console.WriteLine(fileControlRecord.BatchCount);
            break;
        case ChoNACHABatchHeaderRecord batchHeaderRecord:
            Console.WriteLine(batchHeaderRecord.BatchNumber);
            break;
        case ChoNACHABatchControlRecord batchControlRecord:
            Console.WriteLine(batchControlRecord.BatchNumber);
            break;
        case ChoNACHAEntryDetailRecord entryDetailRecord:
            Console.WriteLine(entryDetailRecord.DFIAccountNumber);
            break;
    }
}

To write NACHA file

ChoNACHAConfiguration config = new ChoNACHAConfiguration();
config.DestinationBankRoutingNumber = "123456789";
config.OriginatingCompanyId = "123456789";
config.DestinationBankName = "PNC Bank";
config.OriginatingCompanyName = "Microsoft Inc.";
config.ReferenceCode = "Internal Use Only.";
config.BlockCount = 10;
using (var nachaWriter = new ChoNACHAWriter("ACH.txt", config))
{
	using (var bw1 = nachaWriter.CreateBatch(200))
	{
		using (var entry1 = bw1.CreateDebitEntryDetail(20, "123456789", "1313131313", 22.505M, "ID Number", "ID Name", "Desc Data"))
		{
			entry1.CreateAddendaRecord("Monthly bill");
		}
		using (var entry2 = bw1.CreateCreditEntryDetail(20, "123456789", "1313131313", 22.505M, "ID Number", "ID Name", "Desc Data"))
		{

		}
	}
	using (var bw2 = nachaWriter.CreateBatch(200))
	{
	}
}

ChoNACHAConfiguration

Here are the NACHA configuration available to configure while reading / writing NACHA files using Cinchoo NACHA.

• FieldValueTrimOption - Option to trim the values while parsing. Possible values are None, TrimStart, TrimEnd, Trim.

• FormatCode - Currently there is only one code. Enter 1.
• DestinationBankName - Destination bank name.
