c# - Microsoft.Office.Interop.Excel.ApplicationClass 没有定义构造函数

Question

我试着关注 How to open an Excel file in C# 教程，即在 Com 选项卡上添加对 Microsoft Office 14.0 Object Library 的引用并尝试编译代码:

using Excel = Microsoft.Office.Interop.Excel;
//...
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;

xlApp = new Excel.ApplicationClass();//error here
//...

并遇到编译时错误，说

There is no constructor defined for Microsoft.Office.Interop.Excel.ApplicationClass type.

我错过了什么？

Answer 1

试试这个:

Excel._Application xlApp = new Excel.Application();
