如何对csv导出进行HTML编码

Question

我明白了

 Quattrode® 

从HTML编码为的字符串

Quattrode® 

在Excel 2007中查看时。

常规

        Response.Clear();
        Response.Buffer = true;

        Response.ContentType = "text/comma-separated-values";
        Response.AddHeader("Content-Disposition", "attachment;filename=\"Expired.csv\"");

        Response.RedirectLocation = "export.csv";

        Response.Charset = "";
        //Response.Charset = "UTF-8";//this does not work either.
        EnableViewState = false;

        ExportUtility util = new ExportUtility();

        Response.Write(util.DataGridToCSV(gridViewExport, ","));

基本上DataGridToCSV()使用HttpUtility.HtmlDecode(stringBuilder.ToString()); 我可以使用visual studio的文本可视化工具，看看字符串看起来是否正确（Quattrode®）。

因此， Response过程或Excel对文件的解释中的某些内容不正确。 知道怎么解决？

UPDATE
事实证明，这在Excel或写字板中无法正确解释。 我在记事本中打开它，符号显示正确。

Answer 1

我在这里找到答案https://stackoverflow.com/a/3300854/150342并在这里https://stackoverflow.com/a/6460488/150342然后把这段代码放在一起：

    public static void WriteCSVToResponse(string csv, string filename)
    {
        HttpResponse response = HttpContext.Current.Response;
        response.Clear();
        response.ClearHeaders();
        response.ClearContent();
        response.ContentType = "text/csv";
        response.AddHeader("content-disposition", "attachment; filename=" + filename);
        response.ContentEncoding = Encoding.UTF8;

        byte[] BOM = new byte[] { 0xef, 0xbb, 0xbf };
        response.BinaryWrite(BOM);//write the BOM first
        response.BinaryWrite(Encoding.UTF8.GetBytes(csv));
        response.Flush();
        response.End();
    }

Answer 2

也试试这个

Response.ContentEncoding = Encoding.UTF32;

Answer 3

Response.Charset =“”;

尝试使用像UTF-8这样的东西
