无法将类型'int'隐式转换为'int []' [英] Cannot implicitly convert type 'int' to 'int[]'

问题描述

我正在尝试制作一个策划游戏，我让用户猜测4-10而不是颜色之间的数字序列但由于某种原因我的GetRandomNumberCount，CountHits得到错误不能隐式地将类型转换为int []





任何指导都将不胜感激

 < span class =code-comment> //  此方法将随机数与用户猜测的随机数进行比较 
  public   static   int  CountHits（ int  userGuess， int  [] randomNumbers）
 {
  int  correctGuess =  0 ; 
 
 
  if （userGuess == randomNumbers）
 {
 Console.WriteLine（ 点击）; 
 Console.ReadLine（）; 
 correctGuess ++; 
} 
  else  
 {
 Console.WriteLine（ 小姐）; 
 Console.ReadLine（）; 
} 
  return  correctGuess; 
} 
 

  //  此方法获取在游戏中使用的随机数的数量。 
  public   static   int  GetRandomNumberCount（ int 难度）
 {
  int  [] randomNumber =  0 ; 
 
 
  if （难度==  1 ）
 {
 randomNumber = GenerateRandomNumber（ 0 ， 4 ）; 
} 
 其他 如果（难度==  2 ）
 {
 randomNumber = GenerateRandomNumber（ 1 ， 6 < /跨度>）; 
} 
 其他 如果（难度==  3 ）
 {
 randomNumber = GenerateRandomNumber（ 1 ， 11 < /跨度>）; 
} 
 
  return  randomNumber; 
 
} 
  //  此方法生成数字数组的随机数。 
  public   static   int  [] GenerateRandomNumber（ int  min， int  max）
 {
 
 
  //  这声明了一个包含5个元素的整数数组 
  //  并将所有这些值初始化为默认值 
  //  为零 
  int  [] test2 =  new   int  [ 5 ]; 
 
随机randNum = 新 Random（）; 
  for （ int  i =  0 ; i <  test2.Length; i ++）
 {
 test2 [i] = randNum.Next（min，max）; 
} 
  return  test2; 
} 
 

解决方案

错误是否来自此行

< pre lang =c＃> int [] randomNumber = 0 ;

< br $>
应该 randomNumber 是单个变量而不是数组吗？

int [] randomNumber = new int [ ] {};

I am trying to make a mastermind game where I having the user guess a number sequence between 4-10 instead of colours but for some reason my GetRandomNumberCount, CountHits get the error Cannot implicitly convert type to int[]


Any guidance would be appreciated

// This method compares the random numbers to the ones the user has guessed
       public static int CountHits(int userGuess, int[] randomNumbers)
       {
           int correctGuess = 0;


           if(userGuess == randomNumbers)
           {
               Console.WriteLine("Hit");
               Console.ReadLine();
               correctGuess++;
           }
           else
           {
               Console.WriteLine("Miss");
               Console.ReadLine();
           }
           return correctGuess;
       }

// This method gets the quantity of random numbers to use in the game.
       public static int GetRandomNumberCount(int difficulty)
       {
           int[] randomNumber = 0;


           if(difficulty == 1)
           {
             randomNumber= GenerateRandomNumber(0, 4);
           }
           else if(difficulty == 2)
           {
                randomNumber = GenerateRandomNumber(1, 6);
           }
           else if (difficulty == 3)
           {
               randomNumber = GenerateRandomNumber(1, 11);
           }

           return randomNumber;

           }
       // This method generates the random numbers for the array of numbers.
       public static int[] GenerateRandomNumber(int min, int max)
       {


           // this declares an integer array with 5 elements
           // and initializes all of them to their default value
           // which is zero
           int[] test2 = new int[5];

           Random randNum = new Random();
           for (int i = 0; i < test2.Length; i++)
           {
               test2[i] = randNum.Next(min, max);
           }
           return test2;
       }

解决方案

Is the error coming perhaps from this row

int[] randomNumber = 0;

Should randomNumber be a single variable instead of an array ?

int[] randomNumber = new int[] { };
