在c中的随机数猜谜游戏的麻烦＃

Question

因此，我正在为一个在1-100之间随机生成的数字在猜谜游戏中的学校项目工作。目前我唯一遇到的问题是，每当用户输入一个新号码时，生成的号码也会改变。我试着将代码放在表单加载器中生成数字，但后来在程序中无法访问它。这是迄今为止我所拥有的。

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 
    { 
     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

当前标准的，将Random数字每天都在guessButton_Click功能运行时间覆盖。

您声明Random的guessButton_Click函数内部，即每次guess按钮被点击时间称为（这也是内存泄漏！）。 要解决，声明它作为一个全局变量，在命名空间：

编辑：下面的代码编译正确，和完美的作品。

    { 
     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(); 
     } 
    } 
}

你得到一个新的随机数的每个按钮单击尝试以下操作：

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(); 
    } 


}
