.Net Core service using value from another service-CodePudding

I'm currently trying to find a better way to call a function of a service in the constructor of another class service. I have a bad feeling about what I'm doing and think I'm fighting the foundation of ASP .Net Core. My question is, am I fighting the .Net way? Is there a better way where I'm not creating a new instance of CryptionService?

//this singleton has a function called GetSQLitePassword that returns a string
services.AddSingleton<ICryptionService, CryptionService>();

// Use value returned from cryptionService
services.AddScoped<ISQLiteSettingsRepo, 
    SQLiteSettingsRepo>(x => new SQLiteSettingsRepo(
        "./Settings.db", 
        new CryptionService().GetSQLitePassword()
    ));

I'd like to think that I could do something like this:

services.AddScoped<ISQLiteSettingsRepo, SQLiteSettingsRepo>(x => new SQLiteSettingsRepo(
    "./Settings.db", 
    service.GetService<ICryptionService>().GetSQLitePassword()
 ));

CodePudding user response：

Why do you need the part: x => new SQLiteSettingsRepo(...? You should inject the ICryptionService service on the constructor of SQLiteSettingsRepo
