如何在您创建的私有 void 方法中隐藏所有项目？

Question

所以我创建了自己的可以创建按钮的私有 void

        private void addButtonsToForm()
        {

           for (int i = 0; i < 26; i++)
         {
               Button currentNewButton = new Button();
               currentNewButton.Size = new Size(20, 30);
               currentNewButton.Location = new Point(20 + 25 * i, 420);
               currentNewButton.Text = ((char)(65 + i)).ToString();
               currentNewButton.Click += LetterClicked;
               letters[i] = currentNewButton;
               this.Controls.Add(letters[i]);
          }

        }

按钮是字母，当用户想要选择一个字母时将被访问...但问题是我试图弄清楚当用户单击或选择一个按钮时如何返回..

最初我想做的是我可以隐藏所有创建的按钮并只使前一个按钮可见但由于某种原因它只隐藏唯一被点击的按钮

     //this is under private void LetterClicked(object sender, EventArgs e)
      Button selectedLetter = (Button)sender;
      selectedLetter.Enabled = false;

我想到了像这样的愚蠢代码 addbuttonstoform().visible = false; 但当然那行不通..但你可能会知道我想去哪里......解释起来有点混乱......我是 c# 的新手而且我是创建一个猜字游戏，这样帮助会很大..

这是针对您的问题的有效解决方案。见下文：

using System;
using System.Drawing;
using System.Windows.Forms;

namespace Alphabets
{
    public partial class Form1 : Form
    {
        private Button[] _letters;

        public Form1()
        {
            InitializeComponent();
            AddButtonsToForm();
        }

        private void AddButtonsToForm()
        {
            _letters = new Button[26];
            for (int i = 0; i < 26; i++)
            {
                Button currentNewButton = new Button
                {
                    Name = "BtnLetter"+ ((char)(65 + i)),
                    Size = new Size(20, 30),
                    Location = new Point(20 + 25 * i, 420),
                    Text = ((char) (65 + i)).ToString()
                };
                currentNewButton.Click += LetterClicked;
                _letters[i] = currentNewButton;
                this.Controls.Add(_letters[i]);
            }
        }

        private void LetterClicked(object sender, EventArgs e)
        {
            var selectedLetter = (Button) sender;
            //hide all other buttons
            foreach (var letter in _letters)
            {
                if (letter.Text != selectedLetter.Text)
                {
                    var buttons = this.Controls.Find("BtnLetter" + letter.Text, true);
                    buttons[0].Enabled = false;
                }
            }
        }
    }
}
