c＃collection initializer foreach

Question

是否有可能在c＃中执行类似以下的操作？

var tigerlist = new List<Tigers>(){ Tail = 10, Teeth = 20 };

var tigers_to_cats_approximation = new List<Cat>()
{    
     foreach (var tiger in tigerlist)
     {                 
           new Cat()
           {
               Tail = tiger.Tail / 2,
               Teeth = tiger.Teeth / 3,
               HousePet = true,
               Owner = new Owner(){ name="Tim" }
           }
     }
}

我正在做一些XML apis，进入的请求对象类似于需要出去的响应对象。 如果可能，上述将是非常方便的; 比auto-mapper要多得多。

您可以将Select子句与ToList()一起使用：

var tigers_to_cats_approximation = 
      tigerlist.Select(tiger => new Cat() { 
                     Tail = tiger.Tail / 2, 
                     Teeth = tiger.Teeth / 3, 
                     HousePet = true, 
                     Owner = new Owner(){name="Tim"} })
               .ToList();
