EXCEL操作一（工作区之间的复制）

刚开始接触c#操作excel可能会不知从哪着手，但或许又急需写一个能实现excel自动化的程序，我把必要的步骤和一些最简单的常用操作写在下面，希望能帮到一些网友。

适用于：windows office 2003，visual c# 2008。其他版本可能需要略作改变。

首先

添加引用，方法：项目->添加引用->选择COM项->Microsoft Excel 11.0 Object Library

可能装了office 2003 也没有Microsoft Excel 11.0 Object Library，请重新装一遍。

然后

在using后面添加两行

using Excel = Microsoft.Office.Interop.Excel;
using System.Reflection;

如果不行请换上如下两行试试

using Excel;
using System.Reflection;

上面的没问题后便可以进行对excel的操作了，下面是常用的操作及步骤，有些是必须的

            //创建excel 对象
            Excel.Application exampleExcel = new Excel.Application();
            //设置可视化
            exampleExcel.Visible = true;

            Excel.Workbook aBook;
            Excel.Worksheet aSheet1;
            Excel.Workbook bBook;
            Excel.Worksheet bSheet1;

            //打开工作簿，第一个参数为文件路径，其他参数可暂时不设置
            aBook = exampleExcel.Workbooks.Open(aBookName,
                            Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value,
                            Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);

            //新建一个工作簿，第一个参数为文件路径，可暂时不设置
            bBook = exampleExcel.Workbooks.Add(Missing.Value);

            //选择表
            aSheet1 = (Excel.Worksheet)aBook.Worksheets[1];
            bSheet1 = (Excel.Worksheet)bBook.Worksheets[1];

            //将工作簿a表1中单元格[x,y]中值复制到b表1中单元格[i,j]，如下面将工作簿a表1中单元格A1的值复制赋给了工作簿b表1中单元格C2

            //bSheet1.Cells[i,j] = aSheets1[x,y];

            bSheet1.Cells[2, 3] = aSheet1.Cells[1, 1];

            //关闭工作簿，第一个参数为是否保存修改，第二个为保存为的文件名，第三个可暂不设置
            aBook.Close(false, Missing.Value, Missing.Value);
            bBook.Close(true, bBookName, Missing.Value);
           

            //退出

            exampleExcel.Quit();
