解決辦法：spa

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
HttpContext.Current.Response.Charset = "gb2312";
HttpContext.Current.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}.xls", string.IsNullOrEmpty(fileName) ? DateTime.Now.ToString("yyyyMMddHHmmssfff") : System.Web.HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8)));
HttpContext.Current.Response.BinaryWrite(ms.ToArray());
HttpContext.Current.Response.End();

不過上述方法在firefox上仍是亂碼firefox

終極解決辦法：code

                Encoding encoding;
                string outputFileName = null;
                string browser = HttpContext.Current.Request.UserAgent.ToUpper();
                if (browser.Contains("MS") == true && browser.Contains("IE") == true)
                {
                    outputFileName = HttpUtility.UrlEncode(fileName);
                    encoding = System.Text.Encoding.Default;
                }
                else if (browser.Contains("FIREFOX") == true)
                {
                    outputFileName = fileName;
                    encoding = System.Text.Encoding.GetEncoding("GB2312");
                }
                else
                {
                    outputFileName = HttpUtility.UrlEncode(fileName);
                    encoding = System.Text.Encoding.Default;
                }
                HttpContext.Current.Response.Clear();
                HttpContext.Current.Response.Buffer = true;
                HttpContext.Current.Response.ContentEncoding = encoding;
                HttpContext.Current.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}.xls", string.IsNullOrEmpty(outputFileName) ? DateTime.Now.ToString("yyyyMMddHHmmssfff") : outputFileName));
                HttpContext.Current.Response.BinaryWrite(ms.ToArray());
                HttpContext.Current.Response.End();
