在C#中,ComboBox是一种常用的控件,用于显示一个下拉列表供用户选择。在示例代码中,使用了ComboBox控件,并展示了一些常见的用法。首先,在MainForm加载时,通过调用comboBox.Items.Add()方法来添加选项,并使用comboBox.SelectedIndex = 0设置默认选中项。当选中项发生改变时,会触发comboBox_SelectedIndexChanged事件,并通过comboBox.SelectedItem.ToString()获取选中的选项值。通过btnGetSelected_Click事件可以获取当前选中项的值。通过btnAddOption_Click事件可以添加新的选项。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
