如何禁用单击事件处理程序中的除按钮之外的所有按钮？

Question

我写下面的代码。请别人告诉我，在switch语句中，当我按下其中任何一个按钮时，我怎样才能禁用所有其他按钮。我实际上只希望用户在此应用程序中了解他的运气。

namespace tryAppWFA 
    { 
     public partial class mainWindow : Form 
     { 
    public mainWindow() 
    { 
     InitializeComponent(); 
    } 

    private void button_click(object sender, EventArgs e) 
    { 
     Button button=(Button)sender; 
     switch (button.Name) { 
      case "button1": 
       textBox.Text = "Hey ! you may get a car after one year"; 

       break; 
      case "button2": 
    textBox.Text = "Hey ! you may get a big super duper House after a year"; 
       break; 
      case "button3": 
       textBox.Text = "something"; 
       break; 
      case "button4": 
       textBox.Text = "something"; 
       break; 
      case "button5": 
       textBox.Text = "somehting" 
       break; 
      case "exit": 
       Environment.Exit(0); 
       break; 
      default: 
      break; 

     } 

     } 
     } 
     } 

Answer 1

您可以执行以下操作来实现这一点：
先设置你的按钮Tag属性的按钮名称，格式为您加载事件：

private void MainForm_Load(object sender, EventArgs e) 
{ 
    button1.Tag = button1.Name; 
    button2.Tag = button2.Name; 
    btnExit.Tag = btnExit.Name; 
    //and so on... 

} 

那么你想要做什么是遍历你的控件，并禁用那些不是单击的：
请注意，在这里它认为按钮不在groupbox中，如果这是在这种情况下，您将不得不遍历您的容器，这将是组合框。

private void button5_Click(object sender, EventArgs e) 
{ 
    foreach (Button item in this.Controls.OfType<Control>().Where(c => c.GetType() == typeof(Button))) 
    { 
     if (item.Name == btnExit.Name) 
      continue; 
     item.Enabled = false; 
    } 
    Button button = (Button)sender; 
    switch (button.Name) 
    { 
     case "button1": 
      textBox.Text = "Hey ! you may get a car after one year"; 
      break; 
     case "button2": 
      textBox.Text = "Hey ! you may get a big super duper House after a year"; 
      break; 
     case "button3": 
      textBox.Text = "something"; 
      break; 
     case "button4": 
      textBox.Text = "something"; 
      break; 
     case "button5": 
      textBox.Text = "somehting"; 
      break; 
     default: 
      break; 
    } 
} 

编辑：我也删除从switch语句中的退出按钮。
