Question

所以我正在为学校做一个项目，在猜测游戏中为1-100之间随机生成的数字。我目前遇到的唯一麻烦是，每次用户输入新号码时，生成的号码也会发生变化。我尝试将代码放在表单加载器中生成数字，但后来我无法在程序中访问它。这是我到目前为止所拥有的。

using System.Windows.Forms;

namespace WindowsFormsApplication5
{

    public partial class Form1 : Form
    {
        public Form1()
        {

            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void guessButton_Click(object sender, EventArgs e)
        {

            int userGuess;
            userGuess = int.Parse(guessText.Text);
            Random rand = new Random();
            int number = rand.Next(1, 100);

                label2.Text = "" + number;


                    if (userGuess > number)
                    {
                        resultLabel.Text = "Your guess is too high";
                    }

                    else if (userGuess < number)
                    {
                        resultLabel.Text = "Your guess is too low.";
                    }

            else if (userGuess == number)
            {
                resultLabel.Text = "That is correct!";
            }

                guessText.Clear();



        }

        private void exitButton_Click(object sender, EventArgs e)
        {
            this.Close();
        }
    }
}

Answer 1

目前的情况是，每次Random功能运行时，guessButton_Click号都会被覆盖。

您在Random函数中声明guessButton_Click，每次点击guess按钮时都会调用（这也是内存泄漏！）。要修复，请在命名空间中将其声明为全局变量：

编辑：以下代码编译正确，效果很好。

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace WindowsFormsApplication5 { public partial class Form1 : Form { int number = new Random().Next(1, 100); public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { } private void guessButton_Click(object sender, EventArgs e) { int userGuess; userGuess = int.Parse(guessText.Text); label2.Text = "" + number; if (userGuess > number) { resultLabel.Text = "Your guess is too high"; } else if (userGuess < number) { resultLabel.Text = "Your guess is too low."; } else if (userGuess == number) { resultLabel.Text = "That is correct!"; } guessText.Clear(); } private void exitButton_Click(object sender, EventArgs e) { this.Close(); } } }

每按一次按钮，您将获得一个新的随机数，请尝试以下操作：

    public partial class Form1 : Form
{

    Random rand;
    int number;

    public Form1()
    {
        InitializeComponent();

    }

    private void Form1_Load(object sender, EventArgs e)
    {
        rand = new Random();
        number = rand.Next(1, 100);
    }

    private void guessButton_Click(object sender, EventArgs e)
    {
        int userGuess;
        userGuess = int.Parse(guessText.Text);

        label2.Text = "" + number;


        if (userGuess > number)
        {
            resultLabel.Text = "Your guess is too high";
        }

        else if (userGuess < number)
        {
            resultLabel.Text = "Your guess is too low.";
        }

        else if (userGuess == number)
        {
            resultLabel.Text = "That is correct!";
        }

        guessText.Clear();
    }


}
