How can a readonly static field be null?

Question

So here\'s an excerpt from one of my classes:

    [ThreadStatic]
    readonly static private AccountManager _instance = new AccountManager();

    private Ac         


        

Answer 1

I believe what is happening is that the static field is only being initialized once so when another thread tries to read the field it will be null (since its the default value) because _instance can't be initialized again. Its just a thought but and I could be totally way off but that's what I think is happening.
