方法一 通過GridView(簡評：方法比較簡單，但是只適合生成格式簡單的Excel，且無法保留VBA代碼),頁面無刷新

aspx.cs部分
代碼如下:

using System.Collections;
using System.Configuration;
using System.Data;

strExcelName = strExcelName.Replace(@"/", "");

Data_Link link = new Data_Link();
string strSQL = this.hidParam.Value;
DataSet ds = new DataSet();
ds = link.D_DataSet_Return(strSQL);//獲得想要放入Excel的數據

gvExcel.Visible = true;
