VSTO学习笔记（五）批量编辑Excel 2010 x64

近期因为工作的需要，经常要批量处理大量的Excel文件，如果纯手工一个个修改，非常的麻烦，于是写了这么一个帮助类，希望能对你有所帮助。里面很多方法可以进一步推广，增减适当的参数，部分方法用到了C# 4.0新特性，如果需要调试，请安装Visual Studio 2010。

示例代码下载

本系列所有示例代码均在 Visual Studio 2010 Ultimate RC + Office 2010 Professional Plus Beta x64 上测试通过。 

首先添加引用：

Range.Interior.Color是Office中表示颜色的方法，其返回一个整数，表示一种特定的颜色：

 但是我们平时用的最多的是RGB表示的颜色，可以用

srcsheet.Cells[i, j].Interior.Color != ColorTranslator.ToOle(Color.FromArgb(255, 204, 153))

将ColorIndex与RGB进行关联。

         private   static   void  fn判断工作表是否被保护( string  v_strDir,  string  v_strSheetName)
        {
            StringBuilder sb  =   new  StringBuilder();
            Application app  =   new  Application();
            DirectoryInfo dir  =   new  DirectoryInfo(v_strDir);

             try
            {
                 // 递归查找所有Excel 2007/2010的文件
                 foreach  (FileInfo f  in  dir.GetFiles( " *.xlsx " , SearchOption.AllDirectories))
                {

若不知道Excel工作簿或工作表的密码，可以用Passware进行破解，经过测试，Passware 可以破解Office 2003/2007/2010，其官方主页称可以破解Windows 7 的 BitLocker 加密技术。

小结：

本次通过一系列的实例探讨了Excel的操作方法，我觉得还挺实用，你可以根据需求进行完善。代码仅供测试，如果欲操作的Excel数量巨大，请谨慎使用。

后续篇章我会继续研究Excel中的操作。
