'从服务器收到的重复标题'在带有EPPlus 2.9的Chrome 16中出错

我正在玩EPPlus 2.9 ，由于某种原因，当我尝试使用Chrome 16下载单个.xlsx文件（在IE9中正常工作）时，我Duplicate headers received from server错误中收到的Duplicate headers received from server文件。

我正在使用这个教程 ，我已经缩小了这个问题的代码行：

  Response.AppendHeader("Content-Disposition", "attachment; " + "filename=\"ExcelReport.xlsx\"; " + "size=" + fileBytes.Length.ToString() + "; " + "creation-date=" + DateTime.Now.ToString("R") + "; " + "modification-date=" + DateTime.Now.ToString("R") + "; " + "read-date=" + DateTime.Now.ToString("R")); 

我的使用者：

 Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.75 Safari/535.7 

我在这个Chrome论坛页面上看到，Chrome不喜欢逗号（ , ）在Content-Disposition标题中，并且应该用分号（ ; ）replace。

有人有任何想法或获得相同的错误？

Answer 1

我很笨， DateTime.Now.ToString("R")产生Thu, 26 Jan 2012 02:05:44 GMT

我通过这样做来修复它：

 String timestamp_without_commas = DateTime.Now.ToString("R").Replace(",",""); Response.AppendHeader("Content-Disposition", "attachment; " + "filename=\"ExcelReport.xlsx\"; " + "size=" + fileBytes.Length.ToString() + "; " + "creation-date=" + timestamp_without_commas + "; " + "modification-date=" + timestamp_without_commas + "; " + "read-date=" + timestamp_without_commas); 

我习惯了IE浏览器被胡思乱想和Chrome播放不错…

Answer 2

我有同样的问题，并正确附加后，我也有分号。 我发现我的问题是在文件名中有逗号。 所以我用破折号取代了它们。
