c# - 读取 MT940 文件数据并存入数据库表

Question

我是 MT940 文件的新手，我正在寻找一个示例代码来读取 .mt940 的内容并将其存储在具有相应字段的数据库表中。我正在努力分析它。有什么简单的方法可以解析并保存在表格中吗？

例如下面的行（这不是整个 mt940 只是一行）

:61:2009230923D4086,74NDDTNONREF //NONREF

如何从上述行中检索客户参考（=NONREF）？它不会出现在所有行的相同索引中。有时它从 28index 开始，有时从 30index 开始。

使用正则表达式

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.IO;

namespace ConsoleApp1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.txt";
        const string pattern = @":61:(?'ValueDate'.{6})(?'EntryDate'.{4})(?'Mark'.{2})(?'FundCode'.{1})(?'Amount'[\d,]+)(?'ID'.{4})((?'CustomerReference'.{1,16})(//)(?'BankReference'.*)|(?'CustomerReference'.{1,16}))";
        static void Main(string[] args)
        {
            string data = File.ReadAllText(FILENAME);
            MatchCollection matches = Regex.Matches(data, pattern, RegexOptions.Multiline);

            foreach (Match match in matches)
            {

                string valueDate = match.Groups["ValueDate"].Value;
                string entryDate = match.Groups["EntryDate"].Value;
                string mark = match.Groups["Mark"].Value;
                string fundCode = match.Groups["FundCode"].Value;
                string amount = match.Groups["Amount"].Value;
                string id = match.Groups["ID"].Value;
                string customerReference = match.Groups["CustomerReference"].Value;
                string bankReference = match.Groups["BankReference"].Value;
                Console.WriteLine("ValueDate = {0}, EntryDate = {1}, Mark = {2}, FundCode = {3}, Amount = {4}, ID = {5}, Customer = {6}, Bank = {7}",
                    valueDate, entryDate, mark, fundCode, amount, id, customerReference, bankReference);
            }
            Console.ReadLine();

        }
    }
}
