推荐答案

您可以尝试安装Office。



要使用Interop.Excel，您必须在运行该应用程序的计算机上安装Excel（以及正在构建它。



如果您不想安装Excel，那么您将需要使用另一种操作电子表格的方法，例如OpenXML。



这里有一些建议从C＃创建Excel（.XLS和.XLSX）文件 [ ^ ] - 它不仅适用于C＃

You could try installing Office.

To use Interop.Excel you must have Excel installed on the machine that is running the application (as well as the one that is building it).

If you don't want to install Excel then you will need to use an alternative method of manipulating the spreadsheets e.g. OpenXML.

There are some suggestions here Create Excel (.XLS and .XLSX) file from C#[^] - it's not just for C#

如果这是网络应用程序，不要打扰。您无法在Windows服务，ASP.NET应用程序或任何其他没有人登录控制台的应用程序中使用Office Interop来使用该应用程序。

If this is a web application, don't bother. You cannot use Office Interop in a Windows Service, ASP.NET app, or any other app where there isn't someone logged into the console to use the app.
