C#.NET(WebForm)操作EXCEL打印报表

        大家做系统时,不可避免的要用到打印报表。

        本来在.NET中打印报表这种事用水晶报表是恰当不过的了,技术上来讲不难,而且又好用。但是如果老板让你把几十张表一块打印出来呢,我是一贯用水晶报表的,而且可以导出为PDF格式~EXCEL格式。但是把报表全部一次性导到一个EXCEL文件里,我觉得还是直接调用EXCEL COM 组建比较方便。下面我就列举一下调用EXCEL 所要用到的方法,如果大家能在实际中用EXCEL 打印报表的话,希望有所帮助。

         首先在 Web.Config 中添加模拟帐号

<identity impersonate="true" userName="administrator"password="password" />

         其次 要添加 EXCEL com 组件。如果是EXCEL2003,则添加 EXcel library 11.0 版本。我把用到的引用头文件列举如下:

        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);

          我接着把大家编程中用到的函数列举如下:

using System;

using System.IO;

using System.Text;

using System.Data;

using System.Reflection;

using System.Diagnostics;

using System.Collections;
