C#根据组合框选择启用/禁用多个文本框

Question

我只是一个正在学习如何编码的普通人。我不喜欢代码看起来很草率并且可以合并的时候。话虽如此，我需要整合一些代码，但我未能找到有关如何执行此操作的信息。

我正在尝试根据组合框选择启用/禁用多个文本框。

这是我试图整合的又长又丑的代码

private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
    {
        int Combobox_Process_Selected_Index = comboBox2.SelectedIndex;
        if (Combobox_Process_Selected_Index == 0)
        {

好的，我只想说非常感谢h8red。我从大量的垃圾代码变成了不到 10 行代码。

这是通过将文本框放置在面板中然后根据组合框用户输入启用/禁用它们而得到的代码合并。

        private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
    {
        //set a counter to track textbox number and compare with combobox selection
        int countTB = 0;

        //grab combobox selection and place as an integer
        int Combobox_Process_Selected_Index = comboBox2.SelectedIndex;

        //this looks at each child control in my panel (named panel1)
        foreach (Control child in panel1.Controls)  
        {
            //this looks at each textbox individually and enables them until combo selection is reached and disables the rest
            TextBox textBox = child as TextBox;              
            if (countTB < Combobox_Process_Selected_Index)
            {
                textBox.Enabled = true;
            }
            else
                textBox.Enabled = false;
            countTB++;
        }
    }

你需要一个容器控件类来包含所有的文本框。最简单的是Panel 类。只需将所有 texboxes 添加到panel.Controls，您就可以循环访问它们。您还必须手动设置一个选项卡才能仅启用其中一些选项。
