您如何确定是否在 c# 中单击了任何按钮?

问题描述

我正在尝试制作井字游戏程序，想知道我如何确定是否点击了任何按钮以及它是哪个按钮.我目前正在重复每个按钮内的代码:

I am trying to make a tic-tac-toe program, and want to know how I figure out if any of the buttons was clicked and which button it was. I am currently repeating the code inside every button:

private void button1_Click(object sender, EventArgs e)
{
  button1.Visible = false;
  label1.Text = "X";
  Application.DoEvents();

}
private void button2_Click(object sender, EventArgs e)
{
  button2.Visible = false;
  label2.Text = "X";
  Application.DoEvents();
}

private void button3_Click(object sender, EventArgs e)
{
   button3.Visible = false;
   label3.Text = "X"
   Application.DoEvents();
}

有没有更优雅的方法来做到这一点?

Is there a more elegant way to do this?

推荐答案

有两种方法可以完成您的任务(假设使用 WinForms).

There's two ways to accomplish what you're after (assuming WinForms)..

首先，您可以将所有按钮连接起来以指向同一个事件处理程序......并检查其名称:

First, you could wire up all buttons to point to the same event handler.. and check its name:

// In the form designer code:
this.buttonNW.Click += new System.EventHandler(this.button_Click);
this.buttonN.Click += new System.EventHandler(this.button_Click);
this.buttonNE.Click += new System.EventHandler(this.button_Click);


// in the form code:
private void button_Click(object sender, EventArgs e) {
    Button thisButton = (Button)sender;

    switch (thisButton.Name) {
        case "buttonNW":
            MessageBox.Show("North West button clicked");
            break;
        case "buttonN":
            MessageBox.Show("Northern button clicked");
            break;
        case "buttonNE":
            MessageBox.Show("North East button clicked");
            break;
    }
}

其次，您可以将逻辑放入它自己的函数中，并为每个单独的事件处理程序调用该函数:

Secondly, you could just put the logic into it's own function and call that function for each individual event handler:

private void buttonNW_Click(object sender, EventArgs e) {
    handleButtonClick("buttonNW");
}

private void buttonN_Click(object sender, EventArgs e) {
    handleButtonClick("buttonN");
}

private void buttonNE_Click(object sender, EventArgs e) {
    handleButtonClick("buttonNE");
}

private void handleButtonClick(string buttonName) {
    switch (buttonName) {
        case "buttonNW":
            MessageBox.Show("North West button clicked");
            break;
        case "buttonN":
            MessageBox.Show("Northern button clicked");
            break;
        case "buttonNE":
            MessageBox.Show("North East button clicked");
            break;
    }
}

我个人会选择选项 2，以便一切都清楚.

I would personally go with option 2 so that everything is clear.

不过，这是一个微不足道的练习，因为在井字游戏中您最多只能有 9 个按钮.

It's a trivial exercise though, considering you'll only ever have a maximum of 9 buttons in a tic-tac-toe game.
