  本篇文章扣丁学堂Java培训小编给读者们分享一下C#语言MVC框架Aspose.Cells控件导出Excel表数据,对Java开发感兴趣想要学习Java开发技术的小伙伴就随小编来了解一下吧。 下面就实例为大家分享Aspose.Cells控件导出Excel表数据的具体代码,具体内容如下: @{ ViewBag.Title = "xx"; } <script type="text/javascript" language="javascript"> function getparam() { var param = {}; param.sear = $("#sear").textbox('getValue'); return param; } //这样写是为了传参数 function print_dc() { var param = getparam();//参数 var formobj=$("<form id='form1' action='dcExcel' method='post'></from>"); //参数 $("body").append(formobj); $.each(param,function(i,o){ var input1=$("<input type='hidden' value='"+o+"' name='"+i+"'/>"); input1.appendTo(formobj); }); formobj.submit(); } </script> <input class="easyui-textbox" id="sear" data-options="width:80"/> <button type="button" class="but-primary" onclick="print_dc()"> 汇总</button> public ActionResult dcExcel(stream sear) { DataTable dt = dal.GetKslyTj(" kd='"+sear+"'"); var stream=PrintExcelApose.PrintExcel(dt, Server.MapPath(Path.Combine("../Ex/dd/", "ddd.xls")), "xx信息"); return File(stream, "application/octet-stream", "xx信息.xls"); } using System; using System.Collections.Generic;
