[英]Unable to display/open excel document after published to server! It's fine on local machine but not on server
I want to display the excel document template from a LinkButton click. 我想通过LinkButton单击显示excel文档模板。 However on the server side, I'm not able to do so (instead it just seems like refreshing that page).
但是,在服务器端,我无法做到这一点(相反,似乎只是刷新该页面)。
How do I do this? 我该怎么做呢?

You need to install Office interOp runtime at deployment machine but I think that is not good solution. 您需要在部署计算机上安装Office interOp 运行时 ,但是我认为这不是一个好的解决方案。 Take a look at How to create Excel file dynamically in ASP.NET and Reading Excel files from C# .
看一下如何在ASP.NET中动态创建Excel文件以及如何 从C#读取Excel文件 。
The Office Interop assemblies were never intended to be used for server-side development. Office Interop程序集从未打算用于服务器端开发。 You may want to consider using Open XML instead.
您可能需要考虑使用Open XML。 The following KB article provides a detailed explanation: Considerations for server-side Automation of Office
下面的知识库文章提供了详细的解释: Office的服务器端自动化的注意事项
As @AVD mentioned, you do need to have Office Primary Interop Assemblies installed on the server. 如@AVD所述,您确实需要在服务器上安装Office Primary Interop程序集。 Also, depending on the MS Office version you are trying to use, the 64bit Office Interop assemblies may not be available.
另外,根据您尝试使用的MS Office版本,64位Office Interop程序集可能不可用。
