怎么做到同时按蓝色1，2标记的按钮，使白色标记的7号蓝线消失，3号黑线变蓝，然后1号、2和3和4号，5、6，8依次变白
可以给Form1添加keydown和keyup事件，keydown判断按了ctrl来实现同时选择功能。用计时器依次描白线段，代码如下

同时按键，这个可以使用checkbox，它可以设置成类似button的外观，达到切换按键的目的
- 这有个类似的问题, 你可以参考下: https://ask.csdn.net/questions/7540636
- 这篇博客你也可以参考下：C#窗体实验之设计一个表决器，表决器中有6个候选城市（如北京、上海、深圳、广州、武汉、南京），选择数量有4个选项（1、2、3、4），当选择3时，只能选择三个候选城市
- 除此之外, 这篇博客: C#中的数组，C#中的冒泡排序，（数组中随机出现1-20之间的8位数，且不重复），（数组中随机出现各重复三次的1,2,3，三位数字）中的 冒泡排序 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
口诀：
N 个数字来排队，两两相比小靠前。
外层循环 N-1，内层循环 N-1-i。
int[] array = {12,45,34,44,32,18 }; for (int i = 0; i < array.Length-1; i++) { for (int j = 0; j < array.Length-1-i; j++) { if (array[j]>array[j+1]) { int temp = array[j]; array[j] = array[j + 1]; array[j + 1] = temp; } } } for (int i = 0; i < array.Length; i++) { Console.Write(array[i]+"<"); } Console.ReadLine();
