基本上我的球员名单，我想配对起来，使每个玩家将扮演人人一次。什么是找到这个数据的最快方法是什么？

Basically I have list of players, and I want to pair them up so that each player will play everyone once. What's the quickest way to find this data?

推荐答案

假设选手不出现在列表两次，双为循环是非常快：

assuming that players do not appear in the list twice, a double for loop is very quick:

for (int i=0, i <= playerList.Count - 2, i++)
    for (int j=i+1, j <= playerList.Count - 1, j++)
        //add a new pairing of player i and j
