FileHelpers在字段中引用和逗号

我有一个csv文件，我正在使用FileHelpers解析，我有一个情况，引号和逗号都可以出现在字段中：

逗号：

323,"PC","28/02/2014","UNI001","5000",0,"Return","Returned Goods, damaged",88.00,15.40,"T1","N",0.00,"R","-", 

引用

  148,"SI","13/01/2014","CGS001","4000",1,"5","17" Monitor",266.00,45.39,"T1","Y",311.39,"R","-", 

我的class级是：

 [DelimitedRecord(",")] public class Transaction { public int TRAN_NUMBER; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string TypeText; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string DATE; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string TransactionAccount; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string NOMINAL_CODE; public int DEPT_NUMBER; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string INV_REF; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string DETAILS; public string NET_AMOUNT; public string TAX_AMOUNT; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string TaxCodeName; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string PAID_FLAG; public string AMOUNT_PAID; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string VatReconText; [FieldQuoted('"', QuoteMode.OptionalForBoth)] public string BankReconText; public string RECON_DATE; } 

我发现这个线程FileHelpers嵌套引号和逗号 – 解析错误

 engine.BeforeReadRecord += (sender, args) => args.RecordLine = args.RecordLine.Replace(@"""", "'"); 

但它只会引起问题，而不是逗号。

使用FileHelper可以解决这两个问题，还是应该寻找替代解决方案？

Answer 1

您可以实现BeforeReadRecord事件来“修复”坏线。

 FileHelperEngine engine = new FileHelperEngine(); engine.BeforeReadRecord += BeforeEvent; private void BeforeEvent(EngineBase engine, BeforeReadRecordEventArgs e) { var line = e.RecordLine; // you have to write the following replacement routine... var fixedLine = ReplaceEmbeddedCommasAndQuotesWithSomethingDifferent(line); e.RecordLine = fixedLine; // replace the line with the fixed version } 

在您阅读完记录后，您可以处理它们以反转更换过程以修复它们。

如果您更喜欢在FileHelpers类本身中定义所有逻辑，则可以实现INotifyRead而不是使用该事件。
