如何创建一个 if 语句来检查按钮文本是否已更改为特定值 c#

Question

我目前正在为一个学校项目开发一个小程序，但似乎根本找不到解决方案。

我一直在处理带有显示文本标签的 Windows 窗体。然后是两个按钮。如果您单击了这些按钮中的任何一个，则另一个将被隐藏，并且已单击按钮的文本会发生变化。

现在我想检查这些按钮的文本是否已更改，然后再次单击现在更改的按钮关闭应用程序。以下是我目前所拥有的。

    private void Form1_Load(object sender, EventArgs e)
    {
        label1.Text = "You wake up.\n\n"+
                      "What would you like to do?";

        button1.Text = "I'd like to eat some cerials!";
        button2.Text = "I need to go to the bathroom!";
    }

    private void button1_Click(object sender, EventArgs e)
    {
        label1.Text = "You stand up, go to the kitchen and eat some cerials. Nice!";
        button1.Text = "Hurray, you ate some cerials";
        button2.Hide();

        // if (button1.TextChanged +=)
        // {
        //     
        // }
    }

    private void button2_Click(object sender, EventArgs e)
    {
        label1.Text = "You don't finde the Bathroom in this house and have to use the garden.";
        button2.Text = "You get arested afterwars!";
        button1.Hide();
    }

    public void EndGame()
    {
        Close();
    }

有没有办法真正做到这一点，还是我需要一些解决方法？

编辑：

• 创建新的网络表单应用程序
• 在 Form1 button1,label1,textbox1 上创建
• 双击表单添加LoadEvent

• 双击按钮添加点击事件

  public Form1()
  {
      InitializeComponent();
  }
  
  //copy from here
  public class AppState
  {
      public string labelText { get; set; }
      public bool endGame { get; set; }
      public bool success { get; set; }
      public List<AppState> answers { get; set; }
  }
  
  AppState level = new AppState()
  {
      labelText = "You are ... you can go 1.left 2.right 3.further ",
      answers = new List<AppState>{
         new AppState() {
          labelText = "You are dead",
          endGame = true,
         },
         new AppState() {
          labelText = "You are winner",
          endGame = true,
          success = true
         },
         new AppState() {
          labelText = "You are bla bla.. 1. left 2. right",
          answers = new List<AppState>{
             new AppState() {
              labelText = "You are dead",
              endGame = true,
             },
             new AppState() {
              labelText = "You are winner",
              endGame = true,
              success = true
             }
          }
         }
        }
  };
  
  public void Render()
  {
      label1.Text = level.labelText;
      if (level.endGame)
      {
          button1.Enabled = false;
          if (level.success)
          {
              MessageBox.Show("winner");
          }
          else
          {
              MessageBox.Show("looser");
          }
      }
  }
  
  public void Answer()
  {
      int ans = int.Parse(textBox1.Text);
      level = level.answers[ans - 1];
      Render();
  }
  // copy to here        
  
  //this you need to do manualy with form editor
  private void Form1_Load(object sender, EventArgs e)
  {
      Render();
  }
  
  //this you need to do manualy with form editor
  private void button1_Click(object sender, EventArgs e)
  {
      Answer();    
  }
  

Answer 2

有几种方法可以轻松做到这一点。一种方法是在单击按钮时设置一个全局布尔值。如果您的布尔值命名为 boolean endProgram = false，那么您的 if 语句将如下所示：

if(endProgram)
{
    EndGame()
}

万一你不知道，if(endProgram) 和if(endProgram == true) 是一样的。这仅适用于布尔值。

只需将相同的内容放入另一个按钮单击事件中，就可以了。
