我正在尝试在我的项目中实现FILEHELPER 2.0，但是某些带有“”引用问题的csv文件。它显示错误（显示此错误日志）

我的代码是这样的：

   var engine = new FileHelperEngine<script>();
   engine.Options.IgnoreFirstLines = 1; // skipping the header line

   script[] res = engine.ReadFile("agile.csv");  <<<<< at this line error occred

和我的班级文件：

     [DelimitedRecord(",")]
      public class script
    {
         [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
        public string Symbol;
         [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
        public string Date;
         [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
        public string Expiry;
         [FieldQuoted('"', QuoteMode.AlwaysQuoted)]

       ...
    }

和csv文件是。

“符号”，“日期”，“到期日”，“行使价”，“开盘价”，“高价”，“低价”，“收盘价”，“LTP”，“结算价”，“合约数量” “，”Lacs的营业额“，”Open Int“，”OI的变化“，”潜在价值“

“NIFTY”，“2012年8月31日”，“2012年9月27日”，“5400.00”，“56.00”，“56.90”，“38.05”，“44.45”，“43.55”，“44.45” ，“281087”，“765592.77”，“4845150”，“1334150”，“5258.50”

我看不出您的错误的任何原因：以下代码正常工作：

[DelimitedRecord(",")]
public class Script
{
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string Symbol;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string Date;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string Expiry;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string StrikePrice;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string Open;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string High;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string Low;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string Close;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string LTP;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string SettlePrice;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string NoOfContracts;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string TurnOverInLacs;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string OpenInt;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string ChangeInOI;
    [FieldQuoted('"', QuoteMode.AlwaysQuoted)]
    public string UnderlyingValue;
}

class Program
{
    static void Main(string[] args)
    {
        string input = @"""Symbol"",""Date"",""Expiry"",""Strike Price"",""Open"",""High"",""Low"",""Close"",""LTP"",""Settle Price"",""No. of contracts"",""Turnover in Lacs"",""Open Int"",""Change in OI"",""Underlying Value """ + Environment.NewLine +
            @"""NIFTY"",""31-Aug-2012"",""27-Sep-2012"","" 5400.00"","" 56.00"","" 56.90"","" 38.05"","" 44.45"","" 43.55"","" 44.45"","" 281087"","" 765592.77"","" 4845150"","" 1334150"","" 5258.50""";

        var engine = new FileHelperEngine<Script>();
        engine.Options.IgnoreFirstLines = 1; // skipping the header line

        Script[] validRecords = engine.ReadString(input);

        // Check the third record
        Assert.AreEqual("NIFTY", validRecords[0].Symbol);
        Assert.AreEqual("31-Aug-2012", validRecords[0].Date);
        Assert.AreEqual("27-Sep-2012", validRecords[1].Date);
        // etc...            

        Console.WriteLine("All assertions passed");
        Console.Read();
    }
}

需要正数，如何解决这个错误？
