Question

If I have nested functions in C#, how to exit from both function at once when executing inner function code. (Return; only exits from executing function.)

public void Function1()
{
    Function2();
}

public void Function2()
{
    if (1 == 1)
    {       
        //Exit from both functions
    }
}

Answer 1

Use return codes instead of void functions. Function1 can return if Function2 fails like so:

public void Function1()
{
    if (Function2() == false)
        return;

    // do other code if Function2 succeeded
}

public bool Function2()
{
    if (1 == 1)
    {
        return false;
    }
    else
    {
        return true;
    }
}
