c# - Csv 阅读器异常未处理

Question

我一直遇到这个错误:

An unhandled exception of type 'CsvHelper.CsvReaderException' occurred in CsvHelper.dll

Additional information: No properties are mapped for type 'RPS_String_Parse.Program+FormattedRow'.

但我相信我正在关注 the documentation正确。在引用了“入门”部分后，我实现了这个:

using (var sr = new StreamReader(filePath))
{
    var csv = new CsvReader(sr);
    var records = csv.GetRecords<FormattedRow>();
    foreach (var record in records)
    {
        Console.WriteLine(record.Address1);
    }

    Console.ReadLine();
}

和我的类(class):

public class FormattedRow
{
        public string IDOrderAlpha;
        public string IDOrder;
        public string AddressCompany;
        public string Address1;
        public string Address2;
        public string AddressCity;
        public string AddressState;
        public string AddressZip;
        public string AddressCountry;
        public string ShipMethod;
        public string ContactEmail;
        public string ContactName;
        public string ServiceRep;
        public string CustomerPuchaseOrder;
}

我觉得这应该可行，因为文档指出:

Auto Mapping

If you don't supply a mapping file, auto mapping will be used. Auto mapping will map the properties in your class in the order they appear in. If the property is a custom class, it recursively maps the properties from that class in the order they appear in. If the auto mapper hits a circular reference, it will stop going down that reference branch

我错过了什么？

Answer 1

文档指出它将映射到 Properties。您的类(class)有 Fields。进行此更改:

public class FormattedRow
{
    public string IDOrderAlpha { get; set; }
    // add { get; set; } for all
}

这会将您的字段更改为“自动属性”。
