  • web页面导出到Excel乱码解决

    引言:
    前几天 在做web项目的时候 需要导出页面上的数据 到Excel里面
    但有的时候出现乱码(有de时候不出现 很奇怪)
    原来的代码是这样的:
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.AddHeader("content-disposition",
            "attachment;filename=FileName.xls");
            HttpContext.Current.Response.Charset = "GB2312";
            HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");//.Unicode;//.UTF8;//
            HttpContext.Current.Response.ContentType = "xls"; //"application/vnd.xls";
            System.IO.StringWriter stringWrite = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
            mygridview.RenderControl(htw);
            HttpContext.Current.Response.Write(sw.ToString());
            HttpContext.Current.Response.End();


    如何解决?

    修改为下面的代码 问题就解决了

            HttpContext.Current.Response.ClearContent();
            HttpContext.Current.Response.Write("<meta http-equiv=Content-Type; content=text/html;charset=gb2312>");            
            HttpContext.Current.Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
            HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
            HttpContext.Current.Response.ContentType = "application/excel";
            System.IO.StringWriter sw = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);
            mygridview.RenderControl(htw);
            HttpContext.Current.Response.Write(sw.ToString());
            HttpContext.Current.Response.End();

    仔细比较一下 就是

           HttpContext.Current.Response.Write("<meta http-equiv=Content-Type; content=text/html;charset=gb2312>"); 
          这句话起的作用 (这句话的作用是声明该网页使用gb2312进行编码)
          原来是 HttpContext.Current.Response.Charset = "GB2312";
          我以为有这句话 就可以  看来不行
          还是 使用 <meta http-equiv=Content-Type; content=text/html;charset=gb2312> 比较保险
