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");
