捕獲1-100之間的整數

Question

我試圖在C＃中捕獲1到100之間的數字，我想循環用戶，直到他們輸入正確的結果。 我有以下內容，但它沒有像我期望的那樣進行評估，我的知識差距在哪里？

var input=0;

Console.Write("Enter a number between 1 and 100: ");

while (!int.TryParse(Console.ReadLine(), out input) && input>0 && input <=100)
{
    Console.Write("The value must be a number greater than 0, but less than 100 please try again: ");
}

Answer 1

似乎您缺少一對括號，並且對!int.TryParse(Console.ReadLine(), out input)進行了評估，如果用戶輸入了任何內容，則為false。

嘗試：

var input=0;

Console.Write("Enter a number between 1 and 100: ");

while (!(int.TryParse(Console.ReadLine(), out input) && input>0 && input <=100))
{
    Console.Write("The value must be a number greater than 0, but less than 100 please try again: ");
}

Answer 2

 static void Main(string[] args)
    {
        var input = 0;
        Console.Write("Enter a number between 1 and 100: ");
        while (true)
        {
          if (int.TryParse(Console.ReadLine(), out input) && (input < 0 || input > 100))
            {
                Console.Write("The value must be a number greater than 0, but less than 100 please try again: ");
            }
            else
            {
                Console.WriteLine("Thank you for the correct input");
                break;
            }
        }
        Console.ReadKey();        

    }
