在其中导入带有逗号的csv文件Asp.net

Question

我正在导入csv文件，此csv文件中的列可以包含逗号。所以当我导入它时会增加列数。

3,Stage3,"Desc Stage,test,test2",55.98,98.76

这是行，我希望我的列为：

3,
Stage3,
"Desc Stage,test,test2",
55.98,
98.76

试试这个

    public static string[] splitCSV(string CSVLineWithQuotedTextWithCommas)
    {
        Regex regExToSeperate = new Regex("(?:^|,)(\"(?:[^\"]+|\"\")*\"|[^,]*)", RegexOptions.Compiled);
        List<string> result = new List<string>();
        string curr = null;
        foreach (Match match in regExToSeperate.Matches(CSVLineWithQuotedTextWithCommas))
        {
            curr = match.Value;
            if (0 == curr.Length)
            {
                result.Add("");
            }

            result.Add(curr.TrimStart(','));
        }
        return result.ToArray<string>();
    }
