如何使用C# WinForms处理单个SelectedIndexChanged事件到多个ComboBox？

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    // 处理事件的代码
}

private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
    // 处理事件的代码
}

// 其他ComboBox的SelectedIndexChanged事件处理程序

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    ComboBox comboBox = (ComboBox)sender;
    string selectedValue = comboBox.SelectedItem.ToString();

    // 根据选中的值执行相应的逻辑
    if (selectedValue == "选项1")
    {
        // 执行逻辑1
    }
    else if (selectedValue == "选项2")
    {
        // 执行逻辑2
    }
    // 其他选项的逻辑处理
}

private string sharedData;

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    ComboBox comboBox = (ComboBox)sender;
    string selectedValue = comboBox.SelectedItem.ToString();

    // 更新共享数据
    sharedData = selectedValue;

    // 执行其他逻辑
}

private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
    // 使用共享数据
    string data = sharedData;

    // 执行其他逻辑
}
