我有 ac# 应用程序已移至 64 位机器。此应用程序读入 Excel 文件以获取一些数据输入。我想将此项目构建为 64 位。有什么办法可以让我的程序读入这个文件？我很难相信没有办法使用 Excel 文件作为 64 位应用程序的输入。我已经安装了 Office 2010 64 位以及 2010 Office System Driver Beta：数据连接组件，但没有成功。我确定我只是错过了一些非常简单的东西。我的应用程序与 .xls 和 .xlsx 文件的 32 位环境完美配合。对于 64 位，它仅适用于 .xls 而不适用于 .xlsx。以下代码抛出不支持指定方法的异常（当我尝试在 64 位环境中打开与 xlsx 的连接时。）。

例外：
