Can't make lock object private in static class - why?

Question

In a static class, I have a method which will edit a variable. The class is static because the class is about site detaild and so only one instance is ever required.

Anyway, thread synchronisation is required. I have a lock object, but when I make it private it and say lock (obj){} I get all sorts of errors.

Why is not possible to make the lock object private?

Answer 1

One thought, do you initialise the object statically. Try declaring:

private static object lockObject = new object();

Answer 2

It should work. Are you declaring it as private static ?

private static readonly object lockObject = new object();

public static void Method() {
    lock(lockObject) { 
         // ...
    }
}
