Loading DLLs dynamically from the local disk
While the programming takes place and you refer to your files in NuGet packages programming with dependencies is not a so big deal, but I made an extension app to an existing application which relies basically on the same dll files as the main program.
Now I don't want to actually place the extension in our main application directory because it is more handy to have it versatile and have the user or admin copy it a to a place they like to.
In pseudocode the code while programming looks like this:
using Newtonsoft.Json;
...
public void xyz()
JsonSerializer ObjectSerializer = new JsonSerializer();
... Do Stuff ...
I can be perfectly sure to have the fitting dll file in a local directory on the concerning machines, so there is registry key where I can read the actual path out of.
Without dynamically wanting to load the dll the code runs fine,
but I hope that something like this would be possible (in the Program.cs - without any using directives to 3rd party dlls!!! - namespace might be loaded anyway
):
private static void Main(string args)
string ProgramPath = FindProgramPath();
System.Reflection.Assembly.LoadFrom(ProgramPath + @"System.Net.Http.Formatting.dll");
System.Reflection.Assembly.LoadFrom(ProgramPath + @"Newtonsoft.Json.dll");
... Do Stuff
Should the logic be wrapped around in another file which will be loaded in the current context, maybe as a resource to be sure that the rest of the needed files are loaded accordingly? Or does somebody else know a way to be independent of the folder location without bloating the actual exe file up?
c# .net reflection

Maybe you're looking for assembly binding in app.config? You can set your referenced assemblies toCopyLocal = false
and use app.config to specify the path where these assemblies should be searched for.
