c# - TinyCsvParser 不返回任何结果

Question

我目前正在尝试使用 TinyCsvParser 来解析文件，尽管我的测试内容有很多条目，但返回的结果为 0。代码如下:

映射类:

public class TransactionCsvMapping : CsvMapping<TransactionDto>
{
    public TransactionCsvMapping()
    : base()
    {
        MapProperty(0, x => x.OccurenceDate);
        MapProperty(1, x => x.Name);
        MapProperty(4, x => x.Amount);
    }
}

我正在尝试从 CSV 行创建列表的模型类:

public class TransactionDto
{
    public string Name { get; set; }

    public double Amount { get; set; }

    public DateTime OccurenceDate { get; set; }
}

解析 CSV 文件:

CsvParserOptions csvParserOptions = new CsvParserOptions(true, ',');
CsvReaderOptions csvReaderOptions = new CsvReaderOptions(new[] { Environment.NewLine });
TransactionCsvMapping csvMapper = new TransactionCsvMapping();
CsvParser<TransactionDto> csvParser = new CsvParser<TransactionDto>(csvParserOptions, csvMapper);

var result = csvParser
    .ReadFromString(csvReaderOptions, fileContents)
    .ToList(); //results is empty here!

下面是解析时 fileContents 的内容:

"Date","Transaction","Name","Memo","Amount"
"9/7/2016","DEBIT","DEBIT PURCHASE","Food Yummy","-4.8000"
"9/7/2016","DEBIT","DEBIT PURCHASE","Gas Blah","-28.0000"

其中文字字符串是:

"\"Date\",\"Transaction\",\"Name\",\"Memo\",\"Amount\"\n\"9/7/2016\",\"DEBIT\",\"DEBIT PURCHASE\",\"Food Yummy\",\"-4.8000\"\n\"9/7/2016\",\"DEBIT\",\"DEBIT PURCHASE\",\"Gas Blah\",\"-28.0000\"\n\n"

为什么我在这里没有得到任何结果？我该如何克服这个问题？

我使用您的代码成功获得了结果。

使用 \r\n 而不是 \n 作为换行符或使用 \n 声明换行符

new CsvReaderOptions(new[] { "\n" });
