随机数:0或1

Question

我是否看得太远,看不到选择一个简单的数字:0还是1？

        Random rand = new Random();

        if (rand.NextDouble() == 0)
        {
            lnkEvents.CssClass = "selected";
        }
        else
        {
            lnkNews.CssClass = "selected";
        }

Answer 1

Random rand = new Random();

if (rand.Next(0, 2) == 0)
    lnkEvents.CssClass = "selected";
else
    lnkNews.CssClass = "selected";

Random.Next选择下限(包括)和上限(不包括)之间的随机整数.

Answer 2

如果你想要50/50的概率,我建议:

Random rand = new Random();

if (rand.NextDouble() >= 0.5)
    lnkEvents.CssClass = "selected";
else
    lnkNews.CssClass = "selected";
