我正在开发一个使用 SQLite 的 Outlook 插件。Outlook 引发异常无法绑定程序集。我启用了融合日志，发现“托管程序集”加载正常，因为它可以从以下日志中看到

    *** Assembly Binder Log Entry  (16/08/2012 @ 14:13:37) ***

The operation was successful.
Bind result: hr = 0x0. The operation completed successfully.

Assembly manager loaded from:  C:\Windows\Microsoft.NET\Framework\v4.0.30319\clr.dll
Running under executable  C:\Program Files\Microsoft Office\Office12\OUTLOOK.EXE

但是根据以下异常，它在加载本机程序集时引发异常。

*** Assembly Binder Log Entry  (16/08/2012 @ 14:13:37) ***

The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

我不知道，为什么会这样。这发生在发布版本之后的一台客户端机器上。即使在发布版本之后，在我的机器上它也可以正常工作。

即便如此，即使在异常之后，添加也可以正常工作。

通常大多数 Sqlite 问题是 32 位 / 64 位 dll 不匹配的结果。您需要为您的平台选择最合适的 Sqlite 库：

仅 .NET 版本是混合模式程序集，其中嵌入了原生版本的 sqlite3.dll，而 Mono / .NET 版本包含外部 32/64 位 Windows dll。如果您使用它，您需要将适当的sqlite3.dll复制到您的项目目录中，并将Build Action设置为Copy If Newer。

您应该能够为您的平台使用 Mono 或 Mixed Mode 程序集。
