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\"/>");
