Answer 1

            int n,i, j;
            Console.WriteLine("输入一个奇数为总行数："); 
            n=Int32.Parse(Console.ReadLine());
            for (i = 0; i <= n/2+1; i++)
            {
                for (j = (n / 2 + 1 - i); j > 0; j--)
                {
                    Console.Write(" ");
                }
                for (j =0;j <(i*2-1); j++)
                {
                    Console.Write("*");
                }
                Console.WriteLine(); 
             }
            for (i = 0; i < n / 2 + 1; i++)
            {
                for (j =0; j <(i+1); j++)
                {
                    Console.Write(" ");
                }
                for (j = 0; j < (n/2 - i)*2-1; j++)
                {
                    Console.Write("*");
                }
                Console.WriteLine();
            }
