我在使用 microsoft excel 互操作库的本地计算机上运行 .NET 应用程序。它一直在工作，直到今天我删除了库，然后将其添加回项目中。直到几周前，我一直在使用 Excel 的试用版来运行这个应用程序，甚至在我的试用期到期后它也能正常工作。但我担心现在由于试用期已过，我从项目中删除了库并将其放回原处，这就是导致此错误的原因。我在这里正确吗？重新安装excel是否应该解决这个问题？

这是我尝试运行应用程序时遇到的错误：

Parser Error Message: Could not load file or assembly 'Microsoft.Office.Interop.Excel, Version=14.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

和日志：

此外，我知道 Microsoft 不建议在 .NET 应用程序中使用 excel，因此请不要将其纳入您的答案。谢谢！

我最终Microsoft.Office.Interop.Excel从我的项目中删除了 dll 并更改了我的 web.config 文件中的程序集以匹配在其中找到的程序集C:\Windows\assembly，现在它可以工作了。我被这个问题告知了。
