C# 调试 程序执行位置确定


        private void btTimeTest_Click(object sender, EventArgs e)
        {
            CFunction.Function1();
        }
    public class CFunction
    {
        public static bool b1;
        public static bool b2;
        public static void Function1()
        {
            while (b1)
            {
                Do11();
                Do12();
                Do13();
                System.Threading.Thread.Sleep(100);
            }
            while (b2)
            {
                Do21();
                Do22();
                Do33();
                System.Threading.Thread.Sleep(100);
            }
            //other
        }
    }这个Function1()有很多循环，有时候会执行到里面，长时间得不到退出，当发生这种情况，我想知道，我的程序具体是执行到那个循环(是重复在执行到哪段代码，确定当前执行的代码);
