我创建了一个小型 C# 程序来获取 CSV 文件、修改数据、拆分一些行项目以及添加其他数据列。最后一部分在运行时会引入错误。
Error: Header with name 'Payee_Country'[0] was not found. Header with name 'Payer_Address1'[0] was not found. Header with name 'Payer_Address2'[0] was not found. Header with name 'Payer_City'[0] was not found. Header with name 'Payer_State' [0] was not found. Header with name 'Payer_Zip'[0] was not found. Header with name 'Payer_Country'[0] was not found.下面的代码是我到目前为止所拥有的，例如上面使用的值并不预先存在于 CSV 输入文件中，我不确定如何让它工作，因为我已经尝试过映射，但这只是引入了更多错误。

你是对的。
这似乎是由原始 CSV 文件不包含这些标题引起的
当您使用
csv.GetRecords<CsvRecord>().ToList()直接上课
public class CsvRecord
{
public string GLAccountName { get; set; }
...
[Optional]
public string Payee_Country { get; set; }
...
}
或通过
ClassMapMap(m => m.Payee_Country).Optional();
