FileHelpers 字段中的引号和逗号

Question

我有一个 csv 文件，我正在使用 FileHelpers 进行解析，我遇到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class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(@"""", "'");

但它只有助于解决引号出现的问题，而不是逗号。

这两个问题都可以用 FileHelpers 解决吗？还是我应该寻找替代解决方案？

Answer 1

您可以对 'fix' 您的不良线路实施 BeforeReadRecord 事件。

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
}

在您阅读其中的记录后，您可以处理它们以逆向替换过程来修复它们。

如果您更喜欢在 FileHelpers class 本身中定义所有逻辑，您可以实现 INotifyRead<Transaction> 而不是使用事件。
