问题
I'm using Excel-Dna in a project where connection strings are stored in an external file called connections.config, which is referenced in the App.config file. When building the project, both config files are copied to the bin folder and the App.config file is renamed <Name>-AddIn64-packed.xll.config as it should be.
The problem is that the packed xll still relies on both config files. Everything works fine when including the connection strings directly in the App.config, but I need to keep them outside of the source code.
Any thoughts on how to proceed?
回答1:
As discussed by Hanselman in his blog. Host your own NuGet Server.
My personal preference is a Choco Nuget Server.
- Setup your NuGet Server
- Add your xlls to some folder
Pack your files with NuGet
nuget pack -version 0.0.1
Push your NuGet Package up to the server
nuget push -source \mycompany\repo\ mypackage.1.0.0.nupkg
Recommended Remove any user credentials such as passwords or usernames

Excel-DNA currently does not support App.config external configuration settings via configSource on -packed XLLs if the main .config file + external file is not physically present in the folder where the -packed XLL is.
If you want to use configSource in your case, you'll have to keep these external files together with the -packed XLL, on the same folder.
e.g.
<Name>-AddIn-packed.xll<Name>-AddIn-packed.xll.config<Name>-AddIn64-packed.xll<Name>-AddIn64-packed.xll.configconnections.config
As an alternative, if you want to have the connection strings on an external file, but still embedded within the -packed XLL, then do not use configSource at all, add your connections.config as an embedded resource of your assembly, and read your connection strings from there.
