在同一列表C#中的項(xiàng)目之間進(jìn)行交互（win表單）

Question 1

我試圖創(chuàng)建一個(gè)按鈕列表和一個(gè)文本框列表，我需要在這些元素之間進(jìn)行交互。我的意思是，每當(dāng)我點(diǎn)擊按鈕時(shí)，我需要對(duì)同一行中的文本框執(zhí)行一些操作。我嘗試在點(diǎn)擊事件上使用委托，但我真的找不到指向我想要指向的文本框的方法。

    private void button1_Click(object sender, EventArgs e)
    {
        OpenFileDialog openFileDialog = new OpenFileDialog();
        openFileDialog.Multiselect = true;
        openFileDialog.ShowDialog();

        string[] files = openFileDialog.FileNames.ToArray();

        int index = 0;

        List<Button> EditButtons = new List<Button>();
        List<TextBox> TextBoxes = new List<TextBox>();

        foreach (var file in files)
        {
            EditButtons.Add(new Button() { Text = "Edit", Top = index +50, Left = 150 });
            TextBoxes.Add(new TextBox() { Text = file, Top = index +50, Left = 5 });
            index = index + 25;
        }

        foreach (Button button in EditButtons)
        {
            Controls.Add(button);
        }

        foreach (TextBox textBox in TextBoxes)
        {
            Controls.Add(textBox);
        }
    }

Question 2

標(biāo)簽方法的工作原理如前一個(gè)答案所述，這段代碼應(yīng)該可以工作，只需根據(jù)您的需要更改pnlTextBox和PNLButton即可：

private void button1_Click(object sender, EventArgs e)
    {
        OpenFileDialog openFileDialog = new OpenFileDialog();
        openFileDialog.Multiselect = true;
        openFileDialog.ShowDialog();
        string[] files = openFileDialog.FileNames.ToArray();

        int index = 0;

        
        foreach (var file in files)
        {
            var button = new Button()  { Text = "Edit", Top = index +50, Left = 150 };
            var textBox = new TextBox() { Text = file, Top = index +50, Left = 5 };

                button.Tag = textBox;
                button.Click += Button_Click;

            pnlTextBox.Controls.Add(textBox);//Add the textbox to the container i used a panel here
            pnlButtons.Controls.Add(button);//Add the button to the container i used a panel here


            index = index + 25;
        }
       
    }

private void Button_Click(object sender, EventArgs e)
   {
    var button=((Button)sender);
    var textBox = ((TextBox)(button.Tag));
    textBox.Text = button.Text;//example to access the proper textbox
   }
