问题
I want to use a dll which communicates with a server, while using the DLL in the Console Application in C# it worked fine. But when I am using the DLLs in the Web API project it is not making any logs and also not returning correct response.
The DLL uses a .config file which should be present in the same location as that of the DLL. I have pasted the config file in the bin folder in both the cases but still got the different results.
what would be the possible reason behind this.
回答1:
IIS uses Shadow Copying, i.e. it copies all DLLs from bin into temporary folder. Your configuration file is probably not copied during this process, causing your communication DLL to fail in finding it's .config.
You could either copy .config file to target temporary bin folder during application startup, or disable shadow copying in web.config (with all it's side effects).
