C# 2005 操作Excel 2003，如何引用名称空间？

Question

添加引用 Microsoft.Office.Tools.Excel.dll

Answer 1

添加引用   Microsoft.Office.Tools.Excel.dll 只可以
           using Microsoft.Office.Tools.Excel;
       而不可以
           using Microsoft.Office.Interop.Excel;我要用的是Microsoft.Office.Interop.Excel的DLL或EXE位置

}以前编的处理excel   
用Excel组件，在文件名单.xls中Sheet1的所有学生名单中，找到本人的姓名，同时删除其他同学的行，即仅保留本人所在的行。
在应用里面要添加excel组件
