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("
");
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("
");
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
比较保险
