今天怎麼有客戶反應導出的Excel的亂碼,??!!我記得我測試過的啊,後來我用服務器上的再測了下,確實有的會亂碼有的卻不會,真是奇怪,後來改它的編碼utf-8 big5 都試了,就是不行,網上找了一個遇到同樣問題的朋友的解決方案,確實可行!!不錯,謝謝
被注釋的是我之前用的,不好的方法,
private void BtnPushExcel_Click(object sender, System.EventArgs e)
...{
string fileName = "Excel.xls";
Export(this.DataGrid1,fileName);
// HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename="+HttpUtility.UrlEncode(fileName,System.Text.Encoding.UTF8));
// HttpContext.Current.Response.Charset ="UTF-8";
// //HttpContext.Current.Response.ContentEncoding =System.Text.Encoding.GetEncoding("BIG5");
// HttpContext.Current.Response.ContentEncoding =System.Text.Encoding.GetEncoding("BIG5");
// HttpContext.Current.Response.ContentType ="application/ms-Excel";
// Datagrid2.Page.EnableVIEwState =false;
// System.IO.StringWriter tw = new System.IO.StringWriter() ;
// System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter (tw);
// this.DataGrid1.RenderControl(hw);
// HttpContext.Current.Response.Write(tw.ToString());
// HttpContext.Current.Response.End();
