我有以下列表，我想将model输出到列表中，但要随机进行.我已经看到了一些示例，但是它们似乎真的很混乱.我只是想要一个简单的方法来做到这一点?

Hi I have the following list and I want to output the model into a list but do so randomly. I have seen a few examples but they seem to be really convuluted. I just want a simple way to do this?

List<Car> garage ----randomise------> List<string> models


List<Car> garage = new List<Car>();

garage.Add(new Car("Citroen", "AX"));
garage.Add(new Car("Peugeot", "205"));
garage.Add(new Car("Volkswagen", "Golf"));
garage.Add(new Car("BMW", "320"));
garage.Add(new Car("Mercedes", "CLK"));
garage.Add(new Car("Audi", "A4"));
garage.Add(new Car("Ford", "Fiesta"));
garage.Add(new Car("Mini", "Cooper"));

推荐答案

我想您想要的就是这个，这是一种简单的方法；

I think all you want is this, it's a simple way to do it;

Random rand = new Random();
var models = garage.OrderBy(c => rand.Next()).Select(c => c.Model).ToList();

//Model假设这是您的属性的名称

//Model is assuming that's the name of your property

注意:具有讽刺意味的是，Random()实际上并不是很随机，但是对于快速简单的解决方案来说是很好的.有更好的算法可以做到这一点，下面是其中一个；

Note : Random(), ironically, isn't actually very random but fine for a quick simple solution. There are better algorithms out there to do this, here's one to look at;
