c# - 使用 FileHelpers 填充零

Question

我正在使用 FileHelpers 创建 NACHA 文件。下面的例子

许多属性都是带有前导零的数字，因此它们被定义为字符串。是否有一个属性可以填充 Class 属性中的前导零，类似于FieldTrim/TrimMode删除空格的方式？

[FixedLengthRecord()]
public class FileControlRecord
{
    [FieldFixedLength(1)]
    public int RecordTypeCode = 9; //Constant

    [FieldFixedLength(6)]
    public string BatchCount; //Numeric

    [FieldFixedLength(6)]
    public string BlockCount; //Numeric

    [FieldFixedLength(8)]
    public string EntryAddendaCount; //Numeric

    [FieldFixedLength(10)]
    public string EntryHash; //Numeric

    [FieldFixedLength(12)]
    public string TotalDebit; //$$$$$$$$$$cc

    [FieldFixedLength(12)]
    public string TotalCredit; //$$$$$$$$$$cc

    [FieldFixedLength(39)]
    [FieldNotInFile]
    public string RESERVED; //Blank
}

Answer 1

您必须将 FieldAlign 与填充字符一起使用：

[FixedLengthRecord()]
public class FileControlRecord
{
    [FieldFixedLength(1)]
    public int RecordTypeCode = 9; //Constant

    [FieldFixedLength(6)]
    public string BatchCount; //Numeric

    [FieldFixedLength(6)]
    public string BlockCount; //Numeric

    [FieldFixedLength(8)]
    public string EntryAddendaCount; //Numeric

    [FieldFixedLength(10)]
    public string EntryHash; //Numeric

    [FieldFixedLength(12)]
    [FieldAlign(AlignMode.Right, '$')]
    public string TotalDebit; //$$$$$$$$$$cc

    [FieldFixedLength(12)]
    [FieldAlign(AlignMode.Right, '$')]
    public string TotalCredit; //$$$$$$$$$$cc

    [FieldFixedLength(39)]
    public string RESERVED; //Blank
}
