Ach处理在文件中添加特殊字符

Question

  

我必须生成ACH文件（我的代码在下面）。每当银行处理此事时。它在文件前面添加了一些特殊字符。无法弄清

生成具有NACHA格式的ACH文件的正确方法是什么，以便可以毫无故障地对其进行处理

try
            {
                //Set this flag to fix the issue
                ChoETLFrxBootstrap.IsSandboxEnvironment = false;

                config.DestinationBankRoutingNumber = "xxxxxxxxxx";                
                config.OriginatingCompanyId = "xxxxxxxxxx";
                config.DestinationBankName = ("SOME Bank").ToUpper();
                config.OriginatingCompanyName = ("Organisation Name").ToUpper();
                config.ReferenceCode = ("mgmt").ToUpper();
                config.BlockingFactor = 10;
                var unitowners = Achbll.GetUnitOwnerPaymentList(Dt).ToList();
