ｐａｎｅｌ－－－面板－－－强调显示－－－２

ＣｈｅｃｋＢｏｘ－－－复选框－－－多选－－－３－－－和ＧｒｏｕｐＢｏｘ当中的ＲａｄｉｏＢｏｘ一样，也是通过Ｃｈｅｃｋｅｄ属性检查是否选中。

ＬｉｓｔＢｏｘ－－－Ｉｔｅｍ属性

按下去得到　字符串集合编辑器－－－每换行得一个选项

－如果想要自定义添加到列表当中选项，可以点击添加，添加进去选项

        private void button1_Click(object sender, EventArgs e)
        {
            if (textBox2.Text != String.Empty)
            {
                listBox1.Items.Add(textBox2.Text);
            }
        }

 

ＬｉｓｔＢｏｘ存在一个ＳｅｌｅｃｔｅｄＩｎｄｅｘＣｈａｎｇｅｄ（）选择改变事件

时刻进行检测　异常，Ｌｉｓｔｂｏｘ．ＳｅｌｅｃｔｅｄＩｎｄｅｘ是否合理
