我有一个要用FileHelpers解析的csv文件,并且遇到这样的情况: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","-",

我的课是:
[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;
}

我找到了这个线程
FileHelpers nested quotes and commas - parsing error
engine.BeforeReadRecord += (sender, args) =>
args.RecordLine = args.RecordLine.Replace(@"""", "'");

但这仅有助于报价出现问题而不是逗号。

可以使用FileHelpers解决这两个问题,还是应该寻找替代解决方案?

最佳答案

您可以实现BeforeReadRecord事件来“修复”不良行。

FileHelperEngine engine = new FileHelperEngine<Transaction>();
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
}

阅读完其中的记录后,您可以对其进行处理,以使替换过程反向进行修复。

如果您希望在FileHelpers类本身中定义所有逻辑,则可以实现INotifyRead<Transaction>而不是使用事件。
