How to terminate outer loop in nested loops?

Question

What is the best way to terminate all nested loops in the example below. Once the if statement is true, I want to terminate the outer for statement (with I). In the other words I need the whole loop to stop. Is there better way than setting I to 10?

for (int I = 0; I < 10; I++)
{
    for (int A = 0; A < 10; A++)
    {
        for (int B = 0; B < 10; B++)
        {
            if (something)
                break;
        }
    }
}

I would refactor this to a method, and just call return whenever I need to.

You could also use goto, and I have used goto for this, but it gets frowned upon. Which is dumb; this scenario is why it exists in the language.

void DoSomeStuff()
{
    for (int I = 0; I < 10; I++)
    {
        for (int A = 0; A < 10; A++)
        {
            for (int B = 0; B < 10; B++)
            {
                if (something)
                    return;
            }
        }
    }
}
...somewhere else...
DoSomeStuff();
