c# – CSVReader – CSV文件中不存在字段

我正在使用CSVHelper NuGet软件包,并收到错误“字段不存在于CSV文件”.这是我的代码：

using (TextReader prodFile = System.IO.File.OpenText(filePath))
{
    CsvReader csv = new CsvReader(prodFile);
    List<PulProduct> prodList = csv.GetRecords<PulProduct>().ToList();
}

类

public class PulProduct
    {
        public string PartNumber { get; set; }
        public string PPartNumber { get; set; }
        public string VPartNumber { get; set; }
        public string VPPartNumber { get; set; }
        public string Status { get; set; }
        public string Description { get; set; }
        public decimal ORetail { get; set; }
        public decimal CSRetail { get; set; }
        public decimal BDPrice { get; set; }
        public decimal YDPrice { get; set; }
        public string Hazardous { get; set; }
        public string TruckPart { get; set; }
        public string PartAddDate { get; set; }
        public int AvailabilityWI { get; set; }
        public int AvailabilityNY { get; set; }
        public int AvailabilityTX { get; set; }
        public int AvailabilityCA { get; set; }
        public int AvailabilityNV { get; set; }
        public int AvailabilityNC { get; set; }
        public int AvailabilityNational { get; set; }
        public string Trademark { get; set; }
        public string AdPolicy { get; set; }
        public string PriceChanged { get; set; }
        public string UOM { get; set; }
        public string UPC { get; set; }
        public string BrandName { get; set; }
        public string Country { get; set; }
        public string Weight { get; set; }
        public string CloSEOut { get; set;}
        public string NoShipToCA { get; set; }
        public string Notes {get; set; }
    }

CSVHelper文档说,CSVHelper会自动将我的类映射到CSV文件.我不知道我做错了什么

完全例外是：

An exception of type ‘CsvHelper.CsvMissingFieldException’ occurred in CsvHelper.dll but was not handled in user code

Additional information: Fields ‘PartNumber’ do not exist in the CSV file.

这是一个示例头文件和第一行：

解决方法

您的字段名称和文件列标题不符合空格.在PulProduct中,第一个字段是“PartNumber”.在您的示例文件中,第一列我们“零件号”.在CsvConfiguration对象中将IgnoreHeaderWhiteSpace设置为true将会处理此问题.

using (TextReader prodFile = System.IO.File.OpenText(filePath))
{
    CsvReader csv = new CsvReader(prodFile);
    csv.Configuration.IgnoreHeaderWhiteSpace = true;
    List<PulProduct> prodList = csv.GetRecords<PulProduct>().ToList();
}
