如何使用 FileHelper FieldOptional

Question

我已经添加了 FieldOptional 属性，但是我仍然收到此错误

行：1列：117.分隔符','在字段'<TrackDate>k__BackingField'后找不到（记录字段少，分隔符错误或必须标记下一个字段作为可选）。"

我的领域Class:

[DelimitedRecord(",")]

public class MaltaIn
{
    [FieldOrder(0)]
    public string MilesEventCode { get; set; }
    [FieldOrder(1)]
    public string MilesEventName { get; set; }
    [FieldOrder(2)]
    public string ThirdPartyEventCode { get; set; }
    [FieldOrder(3)]
    public string ThirdPartyEventName { get; set; }
    [FieldOrder(4)]
    public string ThirdPartyReasonCode { get; set; }
    [FieldOrder(5)]
    public string MilesRef { get; set; }
    [FieldOrder(6)]
    public string ThirdPartyRef { get; set; }
    [FieldOrder(7)]
    public string TrackDate { get; set; }

    [FieldOrder(8)]
    public string TrackTime { get; set; }

    [FieldOrder(9)]
    [FieldOptional]
    public string OrderNumber;

我是新手..我没看懂错误:(

跟踪日期之后应该是

[FieldOrder(8)]
[FieldOptional]
public string TrackTime;
