while 循环

while (true) //循环的判断条件，如果条件为真就进入循环体，直到为假跳出循环
                    {
                        Console.WriteLine("world");
                        break ;
                     }
            //控制循环次数
            int i = 1;
            while (i > -1)
            {
                Console.WriteLine(i);
                i--;

            }

break 跳出整个循环

continue 跳出当前循环，还会进入下一次循环

            int j = Convert.ToInt32(Console.ReadLine());
            int kk = 0;
            while (j != 1)
            {
                if (j % 2 == 1)
                {
                    j = 3 * j + 1;
                    kk++;
                    Console.WriteLine(j);
                }
                else
                {
                    j = j / 2;
                    kk++;
                    Console.WriteLine(j);
                }
            }
            Console.WriteLine(k);
           

for循环

            int m = Convert.ToInt32(Console.ReadLine());
            int nn = Convert.ToInt32(Console.ReadLine());

            for (int k1 = 0; n < m; nn++)
            {
                if (nn % 17 == 0)
                {
                    k1 += nn;
                    Console.WriteLine(k1);
                }
            }

do...while 多执行一次

            int k2 = 0;
            do
            {
                Console.WriteLine("111");
                k2++;

            } while (k2 != 1);
