我只是一个学习如何编码的普通人。当代码看起来很草率并且可以合并时，我不喜欢。话虽如此，我需要整合一些代码，但我没有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。
这是我想要巩固的漫长而丑陋的代码
private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)

好的，我只需要非常感谢你h8red。我从大量的垃圾代码到少于10行代码。
通过将文本框放在面板中，然后根据组合框用户输入启用/禁用它们，可以得到代码的合并。
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++;
}
}

您需要一个容器控件类来包含其中的所有文本框。最简单的是Panel类。只需将所有texbox添加到panel.Controls，您就可以循环访问它们。您还必须手动设置选项卡，以便只能启用其中一些选项卡。
