大家做系統時，不可避免的要用到列印報表。
本來在.NET中列印報表這種事用水晶報表是恰當不過的了，技術上來講不難，而且又好用。但是如果老闆讓你把幾十張表一塊列印出來呢，我是一貫用水晶報表的，而且可以導出為PDF格式~EXCEL格式。但是把報表全部一次性導到一個EXCEL檔案裡，我覺得還是直接調用EXCEL COM 組建比較友善。下面我就列舉一下調用EXCEL 所要用到的方法，如果大家能在實際中用EXCEL 列印報表的話，希望有所幫助。
首先在 Web.Config 中添加模拟帳号
<identity impersonate="true" userName="administrator"password="password" />
其次 要添加 EXCEL com 元件。如果是EXCEL2003,則添加 EXcel library 11.0 版本。我把用到的引用頭檔案列舉如下：
private Excel.Application objApp;
private Excel.Sheets objSheets;
private Excel._Worksheet objSheet;
private Excel.Range range;
objApp = new Excel.Application();
objSheet = (Excel._Worksheet)objSheets.get_Item(1);
我接着把大家程式設計中用到的函數列舉如下：
using System;
using System.IO;
using System.Text;
using System.Data;
using System.Reflection;
using System.Diagnostics;
using System.Collections;
