vb.net 导出问题
Response.Clear()
Response.Buffer = True
Response.Charset = "GB2312"
Response.AppendHeader("Content-Disposition", "attachment;filename=001.xls")
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312")
Response.ContentType = "application/excel"
Dim oStringWriter As System.IO.StringWriter = New System.IO.StringWriter
Dim oHtmlTextWriter As System.Web.UI.HtmlTextWriter = New System.Web.UI.HtmlTextWriter(oStringWriter)
GridView1.RenderControl(oHtmlTextWriter)
Response.Output.Write(oStringWriter.ToString())
Response.Flush()
Response.End()
为什么导出来的 没有任何数据 一片空白 ？oStringWriter 这里面有值 但是excel显示 就没任何数据

[解决办法]
没有传送数据的亲

C# code

/*          using System.IO;         */         string fileName = "asd.txt";//客户端保存的文件名          string filePath = Server.MapPath("DownLoad/aaa.txt");//路径         FileInfo fileInfo = new FileInfo(filePath);         Response.Clear();         Response.ClearContent();         Response.ClearHeaders();         Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName);         Response.AddHeader("Content-Length", fileInfo.Length.ToString());         Response.AddHeader("Content-Transfer-Encoding", "binary");         Response.ContentType = "application/octet-stream";         Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");// 这里是你要下载的文件路径         Response.WriteFile(fileInfo.FullName);         Response.Flush();         Response.End();
