c# - EAN128 或 GS​​1-128 解码 c#

标签 c# regex decode

这是EAN128或新名称GS1-128条码的样本

01088888931021461712031510W1040190

我想解码成ais

(01)08888893102146
(17)120315
(10)W1040190

但是条形码可以这样改

1712031510W1040190
(17)120315
(10)W1040190

是否有任何可能的方法可以用正则表达式解决它或者更好的方法是什么

现在我正在尝试这个

public String AICodes(String pAI)
    {
        switch (pAI)
        {
            case "01":
                return "01\\d{14}";
            case "17":
                return "17\\d{6}";
            case "10":
                return "17\\d{6}10[a-zA-Z0-9|]{1,20}";
        }
        return String.Empty;
    }

private void GS1DataConvert(string pBarcode, string pBarfnc)
    {
       Match match = Regex.Match(pBarcode, AICodes(pBarfnc));
        if (match.Success)
        {
            MessageBox.Show(match.Groups[0].Value);
        }
    }

string barfnc = "01";

GS1DataConvert(barcode, barfnc);
barfnc = "17";
GS1DataConvert(barcode, barfnc);
barfnc = "10";
GS1DataConvert(barcode, barfnc);

最佳答案

这是我的解决方案。它具有完整的 AI 列表并支持组分隔符。我将此解决方案用于 DATALOGIC PM9500 扫描仪。所以我不知道其他扫描器的组分隔符或起始代码是否相同。 我故意将 AI 91 到 99 注释掉。长度可以由公司定义。
