在控制台中为用户编号输入设置最大和最小值

Question

Console.WriteLine("     **************************************");
Console.WriteLine("     ****** Reviewer Awarding Points ******");
Console.WriteLine("     **************************************");
Console.WriteLine();
string[]properties= { "Clarity", "Orginality", "Difficulty" };
        
int[] a = new int[3];
int[] b = new int[3];
        
for(int i = 0; i < 3; i++)
{ 
    Console.WriteLine("     ***" + properties[i]+"***");
    Console.Write(" Alice:   ");
            
    a[i] = Convert.ToInt16(Console.ReadLine());
    if(a[i]>100 || a[i] < 1)
        Console.Write("   Bob:   ");
    b[i] = Convert.ToInt16(Console.ReadLine());
    Console.WriteLine();
}
Console.Read();
}

我希望用户输入1到100之间的值（包括1和100）。那么我要做什么？

Answer 1

您的问题不清楚
尝试

   int value;
   do{
   Console.Write("Enter a value");
   value=int.parse(Console.ReadLine());
   }while(value<1 || value>100);

Answer 2

制作一种检查范围内结果的方法：

public int AskInt(string question, int min, int max){

  while(true){
    Console.WriteLine(question);
    string input = Console.ReadLine();

    if(int.Tryparse(input, out int value) && value >= min && value <= max) 
        return value;
  }
}

逃脱循环的唯一方法是输入范围内的有效数字，否则问题只能重复，

然后您可以在代码中多次使用它：

int age = AskInt("Enter an age between 10 and 100: ", 10, 100);
int weight = AskInt("Enter a weight between 100 and 350: " 100, 350);

Answer 3

Try this:

if(a[i]>=100 || a[i] <= 1)
