新程序安装后：System.Runtime.InteropServices.SEHException (0x80004005)：

Question

我的程序在我们公司的 20 多台 PC 上使用，运行没有任何问题。但是现在一台 PC 已经安装了 Inventor 2020，它更新了一些常用的 DLL（我不知道是哪些），因为安装后出现以下错误：

System.Runtime.InteropServices.SEHException (0x80004005): External component has thrown an exception.

应用程序打开 Microsoft 访问的 DBConnection 时发生错误。下面的连接示例之一。

List<string> myList = new List<string>();


OleDbConnection conn = new OleDbConnection(connectionString);

string sql = "select * from PendingOrders";
OleDbCommand cmd = new OleDbCommand(sql, conn);
conn.Open();


OleDbDataReader reader;
reader = cmd.ExecuteReader();

据我了解，有一个 DLL 会抛出异常，我如何确定是哪一个？或者更好的办法是找到一个解决方法让它再次工作。

提前致谢！

更新：使用 DebugView (DbgView.exe) 在用户 PC 上调试后，我可以看到以下内容。

您可以使用 DebugView (DbgView.exe)，它非常适合识别此类异常，来自 SysInternals。
