c# - 用颜色代码写入csv文件

Question

我正在从 Datatable 写入 csv 文件。检查下面的代码

      public static void SaveDataTableToCsvFile(string AbsolutePathAndFileName, DataTable TheDataTable, params string[] Options)
    {
        //variables
        string separator;
        if (Options.Length > 0)
        {
            separator = Options[0];
        }
        else
        {
            separator = ""; //default
        }
        string quote = "";

        FileInfo info = new FileInfo(AbsolutePathAndFileName);

        if (IsFileLocked(info))
        {
            MessageBox.Show("File is in use, please close the file");
            return;
        }
        //create CSV file
        StreamWriter sw = new StreamWriter(AbsolutePathAndFileName);

        //write header line
        int iColCount = TheDataTable.Columns.Count;
        for (int i = 0; i < iColCount; i++)
        {
            sw.Write(TheDataTable.Columns[i]);
            if (i < iColCount - 1)
            {
                sw.Write(separator);
            }
        }
        sw.Write(sw.NewLine);

        //write rows
        foreach (DataRow dr in TheDataTable.Rows)
        {
            for (int i = 0; i < iColCount; i++)
            {
                if (!Convert.IsDBNull(dr[i]))
                {
                    string data = dr[i].ToString();
                    data = data.Replace("\"", "\\\"").Replace(",", " ");
                    sw.Write(quote + data + quote);
                }
                if (i < iColCount - 1)
                {
                    sw.Write(separator);
                }
            }
            sw.Write(sw.NewLine);

        }
        sw.Close();
    }

代码对我有用，但我需要在 csv 的某些单元格中添加颜色代码。

我该怎么做？

CSV是一种没有任何格式化的纯数据格式。毕竟是纯文本文件。所以不，没有办法添加颜色。
