Question

我有一个用FileHelpers解析的csv文件，我的情况是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","-",

我的课程是：

[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;
}

我找到了这个帖子 FileHelpers nested quotes and commas - parsing error

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

您可以实施BeforeReadRecord活动来修复＆＃39;你的坏线。

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
}

在您阅读完记录后，您可以处理它们以撤消更换过程以修复它们。

如果您更喜欢在FileHelpers类中定义所有逻辑，则可以实现INotifyRead<Transaction>而不是使用该事件。
