我在Windows窗体中为一个学校项目编写此代码。它基本上是一个智力游戏，你必须记住数字在正方形中的位置。问题是，我被困在点击显示数字的按钮的一部分。下面是我的代码（更新后的版本仍然没有点击按钮的结果）：

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;

我试着用代码添加按钮，但效果不好，我希望程序允许我点击按钮并实际工作。

对于基本按钮或其他控件，可以通过Visual Studio设计器中的控件属性窗格将控件连接到事件处理程序。但是你想让所有这些按钮使用相同的方法，这有点奇怪。在这种情况下，您可以在代码中连接事件处理程序：

private void InitializeButtons()
{
    buttons = new Button[] { button2, button3, button4, button5, button6, button7, button8, button9, button10, button11, button12, button13, button14, button15, button16, button17, button18, button19, button20, button21, button22, button23, button24, button25, button26 };

    foreach(var button in buttons)
    {
        button.Click += this.Button_Click;
    }
}
  • 请确保此InitializeButtons()方法只被调用一次！*

这也让我很难过：

buttons.OrderBy(b => Guid.NewGuid())

大多数情况下，它只会比O（n）差一点，但有可能进入罕见的病理情况，这需要很长时间才能完成。相反，查找如何进行Fisher-Yates shuffle，这保证为O（n）。
这也让我很难过：

Random random = new Random();

线本身是好的，但它在错误的地方。如果PRNG是长期存在的，而不是局限于一个方法，您的情况会好得多。而是将其范围限定到类（窗体）或应用程序。

要处理按钮上的单击事件，可以双击Form1.cs[Design]文件中的按钮。它将在中添加eventHandler：InitializeComponent();
像这样：this.button1.Click += new System.EventHandler(this.button1_Click);
最好不要修改InitializeComponent文件，但您仍然可以使用以下内容更改行：this.button1.Click += new System.EventHandler(this.Button_Click);当button1被按下时，这将调用你的函数Button_Click（），然后你可以将它应用到你所有的按钮上。
或者（也是最佳实践），您可以将函数InitializeButtons()修改为：

private void InitializeButtons()
        {
            buttons = new Button[] { button2, button3, button4, button5, button6, button7, button8, button9, button10, button11, button12, button13, button14, button15, button16, button17, button18, button19, button20, button21, button22, button23, button24, button25, button26 };
            foreach(var button in buttons)
            {
                button.Click += new System.EventHandler(this.Button_Click);
            }
            startButton.Click += new System.EventHandler(this.startButton_Click);
        }

它将为按钮中的每个按钮创建EventHandler，当您单击按钮时，它将调用函数Button_Click();
