Question

我正在编写我的第一个C＃程序（FizzBuzz），它必须显示9和13的整除以及打印素数。我想我现在已经对大部分代码进行了排序，但无法理解我所拥有的11'无效令牌'和'标识符预期'错误。对此有任何建议将不胜感激。



using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ConsoleApplication10;

namespace Fizzbuzz
{
class Program
    {
        int TotalFizz;
        int TotalBuzz;
        int TotalFizzBuzz;
        int IsPrime;

         public void BeginTesting(); // start testing

                //Step 1 : Print number 1 to 100
            for (int i = 1; i <=; i++)
            {
                string results = "";
                // Step 2 :- Divisable by 9 print Fizz
                public bool IsFizz(i % 9 == 0) results = "Fizz";
                public int TotalFizz (int input);

                // Step 3 :- Divisable by 13 print Buzz
                public bool IsBuzz(i % 13 == 0) results = "Buzz";
                public int TotalBuzz(int input);

                // Step 4 :- Divisable by 9 and 13 print FizzBuzz
                public bool IsFizzBuzz(i % 9 == 0, i % 13 == 0) results = "FizzBuzz";
                public int TotalFizzBuzz(int input);

                // Step 5 :- Print the number as it is if not divisable by 9 or 13
                Console.WriteLine("TotalFizzBuzz")CurrentValue.ToString;
                public bool IsPrime(int input);  

                Console.WriteLine results;
             }

      }

为了给你一个基本的开始，这里是你的函数的一个版本，它主要执行评论所建议的。

    public void BeginTesting() // start testing
    {
        //Step 1 : Print number 1 to 100
        for (int i = 1; i <= 100; i++)
        {
            var results = string.Empty;
            // Step 2 :- Divisable by 9 print Fizz
            if (i % 9 == 0)
            {
                results = "Fizz";
                TotalFizz++;
            }

            // Step 3 :- Divisable by 13 print Buzz
            if (i % 13 == 0)
            {
                results = "Buzz";
                TotalBuzz++;
            }

            // Step 4 :- Divisable by 9 and 13 print FizzBuzz
            if (i % 9 == 0 && i % 13 == 0)
            {
                results = "FizzBuzz";
                TotalFizzBuzz++;
            }

            if (string.IsNullOrEmpty(results))
            {
                // Step 5 :- Print the number as it is if not divisable by 9 or 13
                Console.WriteLine(i.ToString());
            }

            Console.WriteLine(results);
        }
    }

您的代码存在很多问题。我希望这至少会给你一些指示。

你的代码错误

    for (int i = 1; i <=; i++)

尝试这个（只是编译它，看起来应该这样做）。我抽象了你的号码检查，所以你不必一遍又一遍地做同样的剩余检查。

看起来你的事情过于复杂......但我也一直在那里做过。：）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace test
{
    class Program
    {
        static void Main(string[] args)
        {
            BeginTesting();
            Console.ReadLine();
        }

        private static void BeginTesting()
        {
            //Step 1 : Print number 1 to 100
            for (int i = 1; i <= 100; i++)
            {

                // Step 2 :- Divisable by 9 print Fizz
                if (isDivisibleBy(i, 9))
                {
                    Console.WriteLine("Fizz");
                }

                // Step 3 :- Divisable by 13 print Buzz
                else if (isDivisibleBy(i, 13))
                {
                    Console.WriteLine("Buzz");
                }

                // Step 4 :- Divisable by 9 and 13 print FizzBuzz
                else if (isDivisibleBy(i, 9) && isDivisibleBy(i, 13))
                {
                    Console.WriteLine("FizzBuzz");
                }

                // Step 5 :- Print the number as it is if not divisable by 9 or 13
                else
                {
                    Console.WriteLine(i);
                }

            }
        }



        //Create a method to test whether it’s divisible
        private static bool isDivisibleBy(int theNumber, int theDivisor)
        {
            bool isDivisible = false;

            if ((theNumber % theDivisor) == 0)
            {
                isDivisible = true;
            }

            return isDivisible;
        }


    }
}

编辑：我提交后编译，只是为了确定。清理了最后一种方法。
