与程序集文件位置相关的多个API以单文件发布格式被调用时，其行为会发生变化
因为单文件程序集都合并为一个了，所以有一些路径相关的API均无法支持

Assembly-related API behavior changes for single-file publishing format 单个文件发布格式的程序集相关API行为更改

https://docs.microsoft.com/en-us/dotnet/core/compatibility/core-libraries/5.0/assembly-api-behavior-changes-for-single-file-publish+

解决方法
Avoid dependencies on the file location of assemblies when publishing as a single file.
作为单个文件发布时，避免依赖程序集的文件位置。
