Question

我无法显示我在控制台中键入的所有数字。我需要创建一个列表，以显示我猜到的所有数字。

for (int i = 0; i < 100000; i++)
{
    z++; 
    Console.Write("\nGuess the number I imagined: ");

    int c = Convert.ToInt32(Console.ReadLine()); // all of numbers that I type should appear.

    if (b == c)
    {

        Console.WriteLine("\n Congratulations you guessed in {0} attempts. :)",z); // this is just showing how many attempts I had.

        List<int> Attemptsnums= new List<int>();

        Attemptsnums.Add(c); // here I've put c but It only shows last number I entered, I need all of them in line.

        foreach (var element in Attemptsnums)
        {
            Console.WriteLine("Numbers: {0}", element);
        }

        break;
    }
}

Answer 1

您当前正在做的事情有1个主要问题。在“ for循环”中，您始终将“ Attemptsnums”创建为新列表，这意味着在添加“ c”之前，它将始终为空。在“ for循环”之前声明列表，每次都会在列表中添加“ c”。

我还假设出于某种原因，您正在运行多达100,000个for循环。但是，有趣的是，您从未使用过变量“ i”，而是每次都将“ z”加1。 “ z”的开头是什么？如果它从0开始，则可以仅在for循环中删除“ z”，而在显示“ z”的位置可以仅显示“ i”。

移动：

List<int> Attemptsnums= new List<int>();循环外

Attemptsnums.Add(c);如果

之前

Answer 3

尝试

List<int> Attemptsnums= new List<int>();   

for (int i = 0; i < 100000; i++)
{
z++; 
Console.Write("\nGuess the number I imagined: ");

int c = Convert.ToInt32(Console.ReadLine()); // all of numbers that I type should appear.

if (b == c)
{

    Console.WriteLine("\n Congratulations you guessed in {0} attempts. :)",z); // this is just showing how many attempts I had.



    Attemptsnums.Add(c); // here I've put c but It only shows last number I entered, I need all of them in line.

    foreach (var element in Attemptsnums)
    {
        Console.WriteLine("Numbers: {0}", element);
    }

    break;
 }
}
