我有一个用于归档 Exchange 邮箱的 C#/.NET Windows 服务,我最近“打包”了 Veeam O365 Backup DLL,以便能够自动备份 Exchange Online 邮箱。
我将向您展示一些日志,显示该程序运行了一段时间没有问题,然后开始突然失败并出现错误:
- “无法加载文件或程序集‘System.IO.Compression, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’或其依赖项之一。找到的程序集的清单定义与程序集引用不匹配。 ”
...直到服务重新启动:
(见Edit1,我的照片被覆盖了)
堆栈跟踪:

该项目确实引用了System.IO.Compression,尽管:
- Nuget 包版本是“4.3.0”
- 参考上的版本是“4.1.2.0”
- 构建后的文件版本为“4.6.24704”
在我的 .csproj 文件中,我有这个:
<Reference Include="System.IO.Compression, Version=4.1.2.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, processorArchitecture=MSIL">
<HintPath>..\packages\System.IO.Compression.4.3.0\lib\net46\System.IO.Compression.dll</HintPath>
<Private>True</Private>
<Private>True</Private>
</Reference>
我无权访问“Veeam.Core.*”的代码/项目,因为它们是 Veeam O365 备份安装程序随附的 Veeam DLL。
但是在全球范围内,我不明白的是,它工作了一段时间(通常大约一两个小时),然后除非我重新启动服务,否则错误就会开始?
欢迎任何建议!
谢谢

我在我的“Veeam 连接器”项目中添加了更多日志和自定义异常抛出,但它是同一件事:最终错误仍然是关于 System.IO.Compression 丢失,并且输入从未改变:
