Question

I created a class with 6 private static methods and a private constructor. The private constructor runs all of the static methods. I want to call the class’s private constructor in another class, but I’m not able to. All I want is to run this class once without creating an instance of anything. The class populates a small database and I have no need for it other than calling it once.

I could put it into a method, but I don’t want to put unrelated code into my main class. I want everything more separated. I could just do it with a public constructor and create an instance of the class, but I don’t see why I would have to do it that way when an instance isn’t needed.

Is there a good way to accomplish what I’m trying to do?

Why not replace your private constructor with a public static method?

Your original code:

public class DatabaseInitializer
{
    private DatabaseInitializer()
    {
        init1();
        init2();
        ...
    }

    private static void init1() { ... }
    private static void init2() { ... }
    ...
}

Your new code

public class DatabaseInitializer
{
    public static void Init() 
    { 
        init1();
        init2();
        ...
    }

    private static void init1() { ... }
    private static void init2() { ... }
    ...
}

Than you call it:

Main()
{
    DatabaseInitializer.Init();
}
