关于listview的上点击listView1_SelectedIndexChanged_1事件

Question

各位高手，我做的是一个类qq的洗衣店管理系统的导航界面，用listview来动态生成选择项，但点击其中的listView1.SelectedItems[0].SubItems[]中的图标时//我图标是一行的，文字跟下面的case里的一样，老是报错跪求解释   谁的建议有用送40分弹出错误    未处理的“System.ArgumentOutOfRangeException”类型的异常出现在 System.Windows.Forms.dll 中。其他信息: InvalidArgument=“1”的值对于“index”无效。private void listView1_SelectedIndexChanged_1(object sender, EventArgs e)
        {
            switch (listView1.SelectedItems[0].SubItems[0].Text.ToString())
            {
                case "洗衣":
                    
                    break;
                case "未洗":                    break;
                case "已洗":                    break;
                case "过期":                    break;
                case "单价":
                    danjia d1 = new danjia();
                    d1.ShowDialog();
                    break;
                case "VIP":
                    addvip a1 = new addvip();
                    a1.ShowDialog();
                    break;                default:
                    break;
                
            
            }
这是报错行        switch (listView1.SelectedItems[0].SubItems[1].Text.ToString())
            {
                case "洗衣":                    break;
                case "未洗":                    break;
                case "已洗":                    break;
                case "过期":                    break;
                case "单价":
                    danjia d1 = new danjia();
                    d1.ShowDialog();
                    break;
                case "VIP":
                    addvip a1 = new addvip();
                    a1.ShowDialog();
                    break;
                default:
                    break;            }
            switch (listView1.SelectedItems[0].SubItems[2].Text.ToString())
            {
                case "洗衣":                    break;
                case "未洗":                    break;
                case "已洗":                    break;
                case "过期":                    break;
                case "单价":
                    danjia d1 = new danjia();
                    d1.ShowDialog();
                    break;
                case "VIP":
                    addvip a1 = new addvip();
                    a1.ShowDialog();
                    break;
                default:
                    break;            }
        }弹出错误    未处理的“System.ArgumentOutOfRangeException”类型的异常出现在 System.Windows.Forms.dll 中。其他信息: InvalidArgument=“1”的值对于“index”无效。
