指定概率根据随机数执行操作 和苹果机游戏差不多的

public class demo
{
private string _name;

public string Name
{
get { return _name; }
set { _name = value; }
}

private int _rate;

public int Rate
{
get { return _rate; }
set { _rate = value; }
}

public demo(string name, int rate) { _name = name; _rate = rate; }

}
class Program
{
static void Main(string[] args)
{
Random rd = new Random();
demo[] arraylist = new demo[3] { new demo("苹果", 20), new demo("橘子", 80), new demo("香蕉", 10) };
for (var i = 0; i < arraylist.Length; i++)
{
if (rd.Next(0, 101) <= arraylist[i].Rate)
{
//执行
}
else { i++; }
}
}
}
