推荐答案

E_CLASSNOTREG为类未注册".您可能正在使用Office Interop程序集，这需要安装适当版本的Office.

E_CLASSNOTREG is "Class not registered". You are likely using the Office Interop Assemblies, which require the appropriate version of Office to be installed.

如果我必须在Azure上安装MS Excel，该怎么做.

If i have to install MS Excel on Azure, how can i do that.

据我所知，您无法为Azure网站安装它们.您将需要使用Azure虚拟机来安装Office并获得适当的许可.从授权的角度来看，我不确定使用Office服务器端在技术上是否正确".

As far as I am aware, you cannot install them for Azure web sites. You would need to use an Azure Virtual Machine to install office and get appropriate licensing. I'm not sure either if it is technically "correct" to use Office server-side from a licensing perspective.

要考虑的另一种方法是使用 Open XML SDK 它不依赖于已安装的Excel，但可能更难以使用.还有许多其他的第三方库可供选择.

Another option to consider is using the Open XML SDK which does not rely on Excel being installed, but may be more difficult to use. There are many other 3rd party libraries to choose from as well.
