C#根据组合框选择启用/禁用多个文本框

我只是一个普通人，正在学习如何编码。我不喜欢代码看起来邋遢而且可以合并。说到这里，我需要整合一些代码，但是我没有找到关于如何整合的信息

我正在尝试启用/禁用基于组合框选择的多个文本框

下面是我试图整合的冗长而难看的代码

private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)

您需要一个容器控件类来包含所有文本框。最简单的是类。只需将所有文本框添加到

面板。控件

，您就可以在循环中访问它们。您还必须手动设置一个选项卡，以便只启用其中的一部分。

好的，我要说的是非常感谢。我从大量的垃圾代码变成了不到10行的代码

下面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++;
        }
    }

private void组合框2\u SelectedIndexChanged（对象发送方，事件参数e）
{
//设置计数器以跟踪文本框编号并与组合框选择进行比较
int countTB=0；
//抓取组合框选择并作为整数放置
int Combobox\u Process\u Selected\u Index=comboBox2.SelectedIndex；
//这将查看我的面板（名为panel1）中的每个子控件
foreach（面板1.控件中的控件子项）
{
//这将单独查看每个文本框，并启用它们，直到到达组合选择，并禁用其余文本框
TextBox TextBox=作为TextBox的子项；
if（countTB<组合框\u进程\u选定\u索引）
{
textBox.Enabled=true；
}
其他的
textBox.Enabled=false；
countTB++；
}
}
