var rnd = new Random();
var data = datas[rnd.Next(datas.Count)];  //execute immediately

on Database

var rnd = new Random();

var count = data.Count();  //execute

var data = datas.ElementAt(rnd.Next(count)) //no execution

var result = data.ToList(); //execute query

Or
//no execution
var data = datas.OrderBy(p=> Guid.NewGuid()).Skip(rnd.Next(count))
