我有一个巨大的CSV文件(1GB),看起来像这样:

当我尝试使用FileHelpers使用以下代码读取此文件时:
FileHelperEngine engine = new FileHelperEngine(typeof(BGDTMDF));
BGDTMDF[] tab = (BGDTMDF[])engine.ReadFile(path);
我收到错误:
分隔符'|'在第2行的“MDF_SALDOS_MEDIOS”字段后找不到(记录的字段较少,分隔符错误或下一个字段必须标记为可选)。
我的班级看起来像:
[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;
}
(这个类只有一部分(如此巨大)。)
任何帮助?
答案 0 :(得分:1)
我的解决方案是将类中的所有字段标记为[Field Optional]。
