用filehelper填充零

本文关键字：填充 filehelper | 更新日期: 2023-09-27 18:05:58

我使用FileHelpers来创建NACHA文件。在下面的示例

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的工作方式来删除空白?

[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
}

用filehelper填充零

必须使用FieldAlign来填充char:

[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
}

PS:我建议你使用最新版本的库:
