FileHelpers：分隔符“|”田野后找不到

Question

我有一个巨大的 CSV 文件 (1GB)，看起来像这样：

1140|2017|0213065852|2001|99|Ä‚/Ĺ®ÄąÂŚĂ§lĹˇËťĂ_ÂĂˇ'Ă„Ă‡Â¸|-3858,18|4015,36|100,17|19,34|0,00|0,00|0,00|40,00|0,00|0,00|0,00|32,57|0,00|0,00|0,00|0,00|0,00|0,00|0,00|0,00|0,00|12|12|74|18|24620,65|11903,96|29385,35|10993,94|0,00|-2520,88|0|0100|301|02|0302|N|N|N| | |2001-12-27 00:00:00|N|1140|1313|BG4CSXF0|        |2002-01-01 00:28:13| |0,00|0,00|0,00|0,00|0,00|0,00|0,00|0,00|0,00|0,00|0,00

当我尝试使用以下代码使用 FileHelpers 读取此文件时：

FileHelperEngine engine = new FileHelperEngine(typeof(BGDTMDF));
BGDTMDF[] tab = (BGDTMDF[])engine.ReadFile(path);

我收到一个错误：

The delimiter '|' can´t be found after the field 'MDF_SALDOS_MEDIOS' at line 2 (the record has less fields, the delimiter is wrong or the next field must be marked as optional).

我的 class 看起来像：

[DelimitedRecord("|")]
public class BGDTMDF
{
    public string MDF_ENTIDAD;
    public string MDF_CENTRO_ALTA;
    public string MDF_CUENTA;
    public string MDF_ANIO;
    public string MDF_MES;

    [FieldNullValue("def")]
    public string MDF_SALDOS_MEDIOS;

    [FieldNullValue("def")]
    public string MDF_SALDO_DISPUE;

    public string MDF_SALDO_MAX_DEU;
    public string MDF_INTE_COBRAD;
    public string MDF_INTE_PAGADO;
    public string MDF_IMPU_RETENI;
}

（这个class只有一部分（这么大）。）

有什么帮助吗？

Answer 1

我的解决方案是将 class 中的所有字段标记为 [FieldOptional]。
