如何在c#中捕获int[5]数组中的五个连续数字?

这是可能的，但是你的5个整型数组将被初始化为5个零，所以当扫描唯一性时，你的检查失败了，特别是因为这段代码:

if (fiveNumbers[j] == 0)
{
  return false;
}

因此，不需要循环遍历整个数组，而应该保留一个计数器来跟踪数组中已经有多少项。然后，在执行检查时，只检查到该索引，而不包括检查中的其他项，因为它们包含0，但您应该将它们视为未初始化。

您也可以使用其他数据类型来解决这个问题。例如，您可以创建一个可空整数数组，这样您就可以实际检查一个项是否已经有值了。或者(也许是最好的解决方案)您可以使用List而不是array。

您唯一的错误是int.TryParse()将0视为无效，您可以使用另一个if语句来处理异常，但这看起来不太干净

 private static bool CheckWhetherInteger(string userInput)
{
    if (userInput == "0")
    {
       myInteger = 0;
       return true 
    }
    else
    {
        bool result = Int32.TryParse(userInput, out myInteger);
        if (result == false)
            {
            Console.Clear();
            Console.WriteLine("You did not enter an integer.");
        }
    }
    return result;
}

我只是发布解决方案-使用可空整数-根据Golez Trol的建议。在这里，如果有人感兴趣的话:

class Program
{
    static void Main(string[] args)
    {
    #region Catch5IntegerInArrayOfInt[5]
        // The solution to catching five integers in an array of int[5] 
        // is to use nullable integers.
        // Keeping a counter when entering an integer to the array does not appeal to me.
        // With normal integers I cannot catch 0 as one of the numbers
        // because all ints are initialized with 0
        Console.WriteLine("Please enter five unique numbers consecutively.");
        var fiveNumbers = new int?[5];          // do it using an array just the same (as collections were not part of the lectures so far)
        for (int i = 0; i < fiveNumbers.Length; i++)
        {
            Console.WriteLine("Please enter your {0} number:", (Countables)i);
            CatchUsersNumbers(fiveNumbers, i);
        }
        DisplayResult(fiveNumbers);
        Console.WriteLine("'n");

            if (CheckWhetherInteger(userInput) && CheckUniqueness(fiveNumbers, myInteger))
            {
                fiveNumbers[i] = myInteger;
                break;
            }
            else
            {

            {
               return false;
            }
        }
        return true;
    }

        Array.Sort(fiveNumbers);

        for (int i = 0; i < fiveNumbers.Length; i++)
        {
            if (i != fiveNumbers.Length - 1)
                Console.Write(fiveNumbers[i] + ", ");
            else

        }
