将水晶报表数据导出到Excel中不会将CurrencyDecimalSeparator转换成法国文化

Question

我有一个将生成excel报告的代码。我正在使用ASP.NET MVC 4，并且excel导出工作正常，但是当将其翻译为带有文化“ fr-FR”的法语时，货币十进制分隔符excel是'。'而不是“，”。

当我检查区域性详细信息时，它显示 culturename =“ fr-FR” 和 CurrencyDecimalSeparator =“，” 和区域性。LCID= 1036。

当我导出到PDF时，CurrencyDecimalSeparator为'，'，但为'。'。用于导出到Excel。 我尝试了rd.ExportToHttpResponse（ExportFormatType.Excel）和 rd.ExportToHttpResponse（ExportFormatType.ExcelRecord）

是否可以解决此问题。

请找到导出到excel的代码

            // Get crystal report file..
            string rptFile = Convert.ToString(currentReport.ReportFile);
