C＃无效语法错误

Question

我正在写我的第一个C＃程序（FizzBu​​zz），它必须显示9和13的整除以及打印素数。我认为我已经将大部分代码分类出来了，但无法解决我的11'无效标记'和'标识符预期'错误。任何意见，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，下面是你的函数的一个版本，它主要做的是评论表明它应该。

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); 
     } 
    } 

你的代码有很多问题。我希望这至少会给你一些指示。

Answer 2

这是错误的代码

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

我< = ????

Answer 3

试试这个（只是编译它，看起来应该这样做）。我已经抽象了你的数字检查，所以你不必再一次又一次地检查同样的余数。

看起来像你过于复杂的东西......但我一直在那里，也做到了。 :)

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：我编译后提交，只是为了确保。清理最后的方法。
