Please be more detail in describing your problem i.e. with sample data etc.

谢谢你的关注。问题是这样，想用LV做一个考试模块，从一定数量的题库中随机读取一定的不同数量的考题。谢谢支持！

Hi,

I hope that I understand your question/ problem well... that you want to randomly pick a set of questions from a fixed set of questions... ? (even I got stuck in putting the sentence up :p)

You may make use of the Random Number (0-1), multiplies it with 10 and rounds it down to obtain a random number of 0~9.

It is then used to index a set of C.S.V (comma-separated-values) representing the indexes of the questions in a fixed set of questions (array). 

The set of questions are then extracted with a for-loop.

PS: please refer to attached for reference...

hi,

看来是我没把问题说清楚，比如说从1～100个整数中随机生成20个不同的数据。谢谢你的答复。

上面的文章说明如何创建0-100不重复随机数问题。

对随机数组任意取出20个， 利用LV的随机数发生器×80，随机确定开始索引，取出20个即可。
