从名称数组中随机选取的样本名称生成器

Question

是否有一个linq随机选择器从名称数组中随机选择？

var randomname = {"Jess", "Jay", "Jen", "Jack", "Jan"}.select(a => a.random()); 

Answer 1

简单，只需使用一个随机数生成器，并通过它进行排序：

Random rnd = new Random(); 
var randomname = {"Jess", "Jay", "Jen", "Jack", "Jan"}.OrderBy(a => rnd.NextDouble()).First(); 

Answer 2

无需LINQ这里。只要使用Random.Next有上限和下限：

string[] items = { "Jess", "Jay", "Jen", "Jack", "Jan" }; 
Random r = new Random(); 

int index = r.Next(0, items.Length); 
string randomItem = items[index];

Answer 3

您可以使用.skip

Random rand = new Random(); 
int toSkip = rand.Next(0, randomname.Count ); 
randomname.Skip(toSkip).Take(1).First(); //Or without linq a randomname[toSkipe];
