推荐答案

使用Random类，您可以整天生成随机数.

The Random class lets you generate random numbers all day long.

创建一系列您想要的东西随机分配并一次取出一个东西.

在代码中-创建一个List<yourthing>并用您希望分发的所有内容填充它.使用Random类选择一个介于0和列表中的事物数之间的数字(-1).获取值并删除该项目，然后重复执行直到列表为空.

Create a bucket of the things you want to distribute randomly and pull things out one at a time.

In code - create a List<yourthing> and populate it with everything you wish to distribute. Use the Random class to pick a number between 0 and the number of things in the list (-1). Get the value and remove the item then repeat until the list is empty.

如果您需要提取不重复的随机数(可能是名称数组的索引)，那么请看一下在我的提示中从卡片组中随机抽取5张卡片" [ ^ ](我知道这是C++代码，但无论如何，只是算法很重要).

If you need to extract random numbers (might be the indices of your array of names) without repetitions then have a look at my tip "Random extraction of 5 cards from a deck"[^] (it is C++ code, I know, but, anyway, just the algo matters).
