页面数据导出excel表方法.docxVIP

//1、由dataset生成public void CreateExcel(DataSetds,stringtypeid,stringFileName) { HttpResponseresp; resp = Page.Response; resp.ContentEncoding = System.Text.Encoding.GetEncoding(GB2312); resp.AppendHeader(Content-Disposition, attachment;filename= + FileName); string colHeaders= , ls_item=; inti=0; //定义表对象与行对像，同时用DataSet对其值进行初始化DataTabledt=ds.Tables[0]; DataRow[] myRow=dt.Select(); // typeid==1时导出为EXCEL格式文件；typeid==2时导出为XML格式文件if(typeid==1) { //取得数据表各列标题，各标题之间以\t分割，最后一个列标题后加回车符for(i=0;i colHeaders+=dt.Columns[i].Caption.ToString()+\t; colHeaders +=dt.Columns[i].Caption.ToString() +\n; //向HTTP输出流中写入取得的数据信息resp.Write(colHeaders); //逐行处理数据foreach(DataRow row in myRow) { //在当前行中，逐列获得数据，数据之间以\t分割，结束时加回车符\n for(i=0;i ls_item +=row[i].ToString() + \t; ls_item += row[i].ToString() +\n; //当前行数据写入HTTP输出流，并且置空ls_item以便下行数据resp.Write(ls_item); ls_item=; } } else { if(typeid==2) { //从DataSet中直接导出XML数据并且写到HTTP输出流中resp.Write(ds.GetXml()); } } //写缓冲区中的数据到HTTP头文件中resp.End(); } //2、由datagrid生成public void ToExcel(System.Web.UI.Controlctl) { HttpContext.Current.Response.AppendHeader(Content-Disposition,attachment;filename=Excel.xls); HttpContext.Current.Response.Charset =UTF-8; HttpContext.Current.Response.ContentEncoding =System.Text.Encoding.Default; HttpContext.Current.Response.ContentType =application/ms-excel;//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword ctl.Page.EnableViewState =false; System.IO.StringWritertw = new System.IO.StringWriter() ; System.Web.UI.HtmlTextWriterhw = new System.Web.UI.HtmlTextWriter (tw); ctl.RenderControl(hw); HttpContext.Current.Response.Write(tw.ToString()); HttpContext.Current.Response.End(); } 用法：ToExcel(datagrid1); //3、这个用dataviewpublic void OutputExcel(DataViewdv,stringstr) { // // TODO: 在此处添加构造函数逻辑 // //dv为要输出到Excel的数据，str为标题名称GC.Collect(); Application excel;// = new Application(); introwIndex=4;
