尝试打开访问数据库 c# 时出错 - E_FAIL(0x80004005)

问题描述

我正在尝试使用访问数据库制作一个 c# windows 窗体应用程序。昨晚一切正常，但今天早上，当我运行我的应用程序时出现错误。

来自细节的文字：

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog Box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging,the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled,any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog Box.

阅读后，我可以看出第 31 行有问题。

OleDbConnection conexiune = new OleDbConnection("Provider = Microsoft.ACE.OLEDB.12.0; Data Source = Trenuri.accdb");
conexiune.open();

这是我的第 30 行，分别是第 31 行。

我不知道这个错误的真正含义，如果你能帮助我，我将不胜感激。谢谢！
