unity3d：csv读取数据，兼容单元格中包含逗号

public class CSV
{
    public string[] header;
    public List<string> lines;
}

public static class CSVReader {
    private static readonly string splitter = "[liyu]";
    private static readonly string[] splitters = new string[]{splitter};
    public static CSV Read(string text)
    {
        CSV csv = new CSV();
        text = text.Trim().Replace("\r", "") + "\n";

        // read cells
        csv.lines = new List<string>();
        bool startCell = false;
        StringBuilder line = new StringBuilder();
        for(int i=0; i<text.Length; ++i)
        {
            char c = text[i];
            if(c == '"')
            {
                if(text[i+1] == '"') i++;
                else
                {
                    startCell = !startCell;
                    continue;
                }
            }
            else if(!startCell && c == ',')
            {
                line.Append(splitter);
                continue;
            }
            else if(!startCell && c == '\n')
            {
                csv.lines.Add(line.ToString());
                line.Length = 0;
                continue;
            }
            line.Append(c);
        }
        string lastLine = line.ToString().Trim();
        if(!string.IsNullOrEmpty(lastLine)) csv.lines.Add(lastLine);

        // add line number
        //csv.lines = csv.lines.Select((t, index) => string.Format("{0}{2}{1}", (index > 0 ? (index+1).ToString() : "line"), t, splitter)).ToList();

        // get header
        csv.header = ParseLine(csv.lines[0]);
        csv.lines.RemoveAt(0);

        return csv;
    }

    public static string[] ParseLine(string line)
    {
        return line.Split(splitters, StringSplitOptions.None);
    }

}

public class CSVMgr
{
    public static List<string[]> GetData(string path)
    {
        string tipString = JsonMgr.GetJsonString(Application.streamingAssetsPath + "/" + path);

        List<string[]> rows = new List<string[]>();
        CSV csv = CSVReader.Read(tipString);
        csv.lines.ForEach(line => rows.Add(CSVReader.ParseLine(line)));
        return rows;
    }
}

读取时把csv文件转化为List

        List<string[]> rows = new List<string[]>();
        rows = CSVMgr.GetDataOri("CsvTest.csv");
        for (int i = 0; i < rows.Count; i++)
        {
            m_dic[rows[i][0].ToString()] = rows[i][1].ToString();
        }

由于excel导出csv不好转utf8，并且不能打开时跑程序，所以推荐个编辑器Ron‘s Editor
csv编辑器https://www.ronsplace.eu/Products/RonsEditor/Download

编辑器中

用txt打开

说明：
1.如果单元格中包换了英文逗号，txt中会自动加上”“包住整个单元格
2.如果单元格中包含了英文双引号，txt中会自动再加上一层双引号

所以，在程序读取时
1.先重新组装每一行，碰到单个字符为”,判断后一个有无引号，有即是单元格中包含字符”,无即是单元格中包含字符,

for (int i = 0; i < text.Length; ++i)
        {
            char c = text[i];
            if (c == '"')
            {
                if (text[i + 1] == '"') i++;
                else
                {
                    startCell = !startCell;
                    continue;
                }
            }
            else if (!startCell && c == ',')
            {
                line.Append(splitter);
                continue;
            }
            else if (!startCell && c == '\n')
            {
                csv.lines.Add(line.ToString());
                line.Length = 0;
                continue;
            }
            line.Append(c);
        }

2.判断到字符,作用是分隔符，用个字符串替”[liyu]”换它，解析时用这个特定字符Split切割，这样兼容单元格中包含逗号

line.Split(splitters, StringSplitOptions.None);
