Asp.NET导出Excel文件乱码 终极解决方法

System.Web.UI.WebControls.DataGrid datagrid=new System.Web.UI.WebControls.DataGrid();

            datagrid.ID="excelGrid1";

            

            datagrid.DataSource=data;

            datagrid.DataBind();



            string filename = "table.xls";

            

            filename = System.Web.HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(filename));



            //导出

            System.Web.HttpContext.Current.Response.Clear(); 

            System.Web.HttpContext.Current.Response.Buffer= true; 

            System.Web.HttpContext.Current.Response.Charset="UTF-8";   //GB2312 

            System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename="+filename); 

            System.Web.HttpContext.Current.Response.ContentEncoding=System.Text.Encoding.GetEncoding("UTF-8");//设置输出流为简体中文

            System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 

            datagrid.EnableViewState = false;    

            System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);

            System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad); 

            System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);        

            datagrid.RenderControl(oHtmlTextWriter); 

            System.Web.HttpContext.Current.Response.Write("<meta http-equiv=\"content-type\" content=\"application/ms-excel; charset=UTF-8\"/>");

            System.Web.HttpContext.Current.Response.Write(oStringWriter.ToString());

            System.Web.HttpContext.Current.Response.End();

重点在

Write("<meta http-equiv=\"content-type\" content=\"application/ms-excel; charset=UTF-8\"/>");
