c# - このループで何が間違っていますか?

Question

このコードは、実行時に完全にループする必要があり、ループなしで完全に正常に実行されますが、ループを追加すると最初の部分は正常に動作しますが、別の数値を入力すると、以前とまったく同じ結果が表示され、変更されることはありません、また、それが想定されているときに終了しません。ばかげたことのように思えるかもしれませんが、私はこれが初めてです。間違った種類のループを使用していませんか?

Answer 1

public static void Main()
{
Console.WriteLine("Please enter a number ");
string inputString;
inputString = Console.ReadLine();
int input;
input = int.Parse(inputString);    
while(input !=0)
{
FizzBuzz fizzbuzz = new FizzBuzz();
Console.WriteLine("IsFizz {0}", fizzbuzz.IsFizz(input)); 
Console.WriteLine("IsBuzz {0}", fizzbuzz.IsBuzz(input)); 
Console.WriteLine("IsFizzBuzz {0}", fizzbuzz.IsFizzBuzz(input));
Console.WriteLine("IsPrime {0}", fizzbuzz.IsPrime(input)); 
Console.WriteLine("Fizz Count total is {0}", fizzbuzz.TotalFizz());
Console.WriteLine("Buzz Count total is {0}", fizzbuzz.TotalBuzz());
Console.WriteLine("FizzBuzz Count total is {0}", fizzbuzz.TotalFizzBuzz()); 
Console.WriteLine("Prime Count total is {0}", fizzbuzz.TotalPrime());
Console.WriteLine("Please enter another number or press 0 to exit");
inputString = Console.ReadLine();
input = int.Parse(inputString);  
}
}

Answer 2

inputStringint に変換してinput変数に設定します。

while(input !=0) 
{
    FizzBuzz fizzbuzz = new FizzBuzz();

    Console.WriteLine("IsFizz " + fizzbuzz.IsFizz(input)); //Shows if IsFizz is true or false
    Console.WriteLine("IsBuzz " + fizzbuzz.IsBuzz(input)); //Shows if IsBuzz is true or false
    Console.WriteLine("IsFizzBuzz " + fizzbuzz.IsFizzBuzz(input)); //Shows if IsFizzBuzz is true or false
    Console.WriteLine("IsPrime " + fizzbuzz.IsPrime(input)); //Shows if IsPrime is true or false
    Console.WriteLine("Fizz Count total is " + fizzbuzz.TotalFizz()); //Shows the total amount of Fizz counters 
    Console.WriteLine("Buzz Count total is " + fizzbuzz.TotalBuzz()); //Shows the total amount of Buzz counters 
    Console.WriteLine("FizzBuzz Count total is " + fizzbuzz.TotalFizzBuzz()); //Shows the total amount of FizzBuzz counters 
    Console.WriteLine("Prime Count total is " + fizzbuzz.TotalPrime());
    Console.WriteLine("Please enter another number or press 0 to exit");//Shows the total amount of Prime counters 
    inputString = Console.ReadLine();

    // try to convert, if is not succedde, keep the original value (0).
    int.TryParse(inputString, out input);
}

この行

input = int.Parse(inputString);

ループ内にある必要があります。
